Technical Article: Passive Component Advancements for SPE Connectors and Circuit Protection Devices

Passive Component Advancements for SPE Connectors and Circuit Protection Devices Written By: Daniel West | Julian Wilson Abstract: As Single Pair Ethernet (SPE) begins to roll out there will be a need for easy to implement, yet reliable wire-to-board interconnects. Purchasing finished cable and connector assemblies is not always economical or viable. However, it is also undesirable to work with time consuming and difficult to process connectors. Insulation Displacement Connectors (IDC) and Press-Fit technology (images below) require no crimping or soldering processes, and is easily converted to a streamlined process, while maintaining the versatility of cable lengths and positioning. In addition to reliable retention forces and gas tight seals afforded by the cold weld mechanism of IDC, signal integrity is

Tantalum Capacitors for Electric Vehicles Written By: Jeff Lee Abstract: An electric vehicle is a car powered by electricity unlike internal combustion locomotives that obtain driving energy by burning fossil fuels, they rotate the motor with electricity accumulated in the battery to obtain driving energy. Electric vehicles are largely composed of on-board chargers (OBC), electric power control units (EPCUs), motors, speed reducers, and high voltage battery. The motor of an electric vehicle is a high-efficiency and high-power driving motor and has high output and rotational power. Unlike internal combustion vehicle engines, the electric motor can be made to minimize noise and vibration generation while driving.

Technical Article: DC Bias Characteristics of Ceramic Capacitors

DC Bias Characteristics of Ceramic Capacitors Written By: Simon Cen Abstract: Most electrical engineers are at least familiar with the different ratings of ceramic capacitors, such as C0G and X7R. In many applications, the meaning of these character codes is relatively unimportant as some other factor, like price or size, may be driving component selection. Designers must be wary, however, as choosing the wrong combination of capacitor dielectric and applied voltage can have critical performance implications for the associated circuit. For class two dielectrics, the change in bulk capacitance with DC bias can be substantial. Understanding why this happens and how to choose a proper ceramic capacitor can eliminate this common pitfall.

Technical Article: Low Inductance Capacitors for High-Speed Decoupling

Low Inductance Capacitors for High-Speed Decoupling Written By: Robert Lu Abstract: Modern integrated circuits (IC’s) consume power at rapidly varying rates due to the density of circuits on-board and the extreme speed at which they can operate. Power supplies are required to respond to these changes in load current while maintaining a constant operating voltage. This task is becoming increasingly difficult as the complexity of power distribution networks grows and printed circuit board (PCB) design requires optimization for parasitic inductance and capacitance. Therefore, any power supply performance slack must be absorbed by the all-too-common decoupling capacitor. As shown in Figure 1, a decoupling capacitor is simply an additional parallel capacitance that provides a stable voltage and source of current when

Update on Stacked Ceramic Capacitors for Defense Applications

Update on Stacked Ceramic Capacitors for Defense Applications

MIL-PRF-32535 for discrete MLCCs has led to the discussion of stacked ceramic capacitors based on BME technology. Stacked ceramic capacitors are multiple discrete multi-layer ceramic capacitors (MLCCs) terminated onto a common lead-frame for through-hole or SMT operations. They capture many of the inherent benefits of MLCC technology, like a low-loss material set, low ESR (equivalent series resistance), and higher reliability. Typical applications like switch mode power supplies need larger capacitance values and current capabilities. Stacked MLCCs compete with discrete electrolytic capacitor technology in terms of capacitance range but have an advantage in terms of voltage and temperature capability, which naturally increases their reliability, thereby making this a preferred technology for defense applications despite its higher price point compared to electrolytics.

Technical Article: Polymer Solid Electrolytic Capacitors for Automotive Applications

Polymer Solid Electrolytic Capacitors for Automotive Applications Written By: Jaroslav Tomasko | Slavomir Pala Abstract: Tantalum electrolytic capacitors are constructed using a sintered pellet of powdered tantalum as the anode of the device. A grown oxide layer on the contoured surface of the pellet acts as the dielectric insulator, and a cathode terminal is formed using either a conventional MnO2 electrolyte or a conductive polymer to sufficiently contact the oxide layer. The final capacitor can be packaged in many forms, and the typical J-lead surface mount construction is shown in Figure 2. The capacitive structure is bonded to a molded case and electrically interfaced using carbon as a separation layer and silver for connection with the lead frame.

Technical Article: Analysis of the DC Blocking Capacitor for Stereo High-Fidelity Audio

Analysis of the DC Blocking Capacitor for Stereo High-Fidelity Audio Written By: Rick Liu Abstract: The representation of audio signals in analog and digital electronics can take many forms. Still, they must ultimately be converted back to their mechanical origins as the motion of air molecules propagating as waves. These waves are generated by moving a mass, often the cone of a speaker, back and forth around a neutral position. As such, any fixed offset in the audio signal, represented by a DC bias, is simply a waste of energy and possibly a source of imbalance in the resulting sound wave. Series blocking capacitors are generally used for each audio channel to eliminate the potential of any DC component. While

Technical Article: Variability and Tolerance of Ceramic Capacitors

Variability and Tolerance of Ceramic Capacitors Written By: Robert Lu Abstract: The multi-layer ceramic capacitor (MLCC) is one of the most common capacitor varieties found in electronic design. It offers a wide range of bulk capacitance and voltage tolerance in numerous form factors at relatively low cost. While these devices have become commonplace in the designers’ tool chest, they exhibit some often overlooked peculiarities. Of primary concern is the sensitivity of effective capacitance to several environmental factors, including temperature, applied bias voltage, and age. If these factors are unaccounted for, the risk of product failure becomes very real, especially in manufacturing variability and overall tolerance stack-up.

Aluminum Electrolytic Capacitor Performance and Circuit Impacts

Aluminum Electrolytic Capacitor Performance and Circuit Impacts

A growing number of applications, ranging from solar power converters all the way to miniature power supplies for highly complex processing cores, are starting to capitalize on the benefits of aluminum electrolytic capacitors. Aluminum electrolytics are also increasingly used to satisfy miniaturization demands in complex power tree applications like FPGAs powered by multiple voltages. And while it’s true that aluminum electrolytics also come with disadvantages, several of the more well-known ones are no longer true, and other perceived disadvantages can be reduced or eliminated by selecting newer components engineered to overcome some of the technology’s traditional shortcomings.
