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.
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.

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
The new online tool and global design support service will help customers quickly and confidently select crystal timing devices optimized for their ICs. FOUNTAIN INN, S.C. (February 13, 2023) – KYOCERA AVX, a leading global manufacturer of advanced electronic components engineered to accelerate technological innovation and build a better future, has introduced a new circuit matching service designed to help customers quickly and confidently select suitable crystal timing devices. When oscillator circuits aren’t optimized for customers’ ICs or timing devices, it can result in abnormal oscillation or even prevent oscillation, which could lead to device failure. The new online circuit matching service identifies KYOCERA AVX crystal timing devices recommended by leading global IC manufacturers to ensure that customers choose compatible
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.
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.
