The Pros and Cons of MLCC Downsizing Written By: Frank Hodgkinson | Maureen Strawhorne Abstract: As integrated circuits (ICs) continue to pack more functionality into smaller packages, the need for bulk off-chip capacitance remains. In resonant circuits, such as phase-lock-loops (PLLs) and switching regulators, precision class one ceramic capacitor may be required. Such capacitors must maintain a tight capacitance range over process, voltage, and temperature variation (PVT) for the host IC to meet its performance specifications. In contrast, class two ceramic capacitors are required for nearly every IC in the form of decoupling and bypass capacitance. They may also be found in amplifier circuits, simple filters, and linear regulators where their function is less dependent on tightly specified impedance requirements.

The Application of Capacitors in Power Supply Regulator Circuits Written By: Rick Liu Abstract: Advancements in electronic technology over the last decade have led to smarter consumer electronics. As devices become smarter, the components used to power them are shrinking, resulting in small, but incredibly powerful devices — ones small enough to fit inside a pocket or around a wrist. With these smaller, denser designs, it can be impossible to separate analog and digital domains in the layout, as best practices used to dictate years ago. Today, design engineers are compelled to use many capacitors in the power network to attenuate high-frequency digital noise. Circuits are designed to expect pure, clean power without noise that will impact analog circuits.
Tantalum Capacitors: Characteristics and Component Selection Written By: Raul Wang Abstract: Capacitors are one of the fundamental building blocks of electrical circuits. Whether they are being used for energy storage, noise filtering, or timing/frequency design, capacitors are important in many common electrical devices. Today, various capacitor technologies are available, each with their own unique benefits and drawbacks, making each type ideal for different applications. Tantalum capacitors offer many interesting characteristics that combine to offer a unique solution to many design problems.

Connector Solutions for Automotive & Transportation Applications Written By: Matthew Lawrence Abstract: Wiring interconnect in the transportation sector continues to evolve at an extremely fast pace. Automotive technologies, largely driven by electric vehicles and self-driving systems, are placing particularly stringent demands on wiring connectors. On one hand, high-speed busses like automotive ethernet are reducing total wire weight and complexity. On the other hand, reliability requirements are becoming more demanding with 200,000-mile lifetime expectations and routine reliance on highly advanced sensor technologies such as radar and video.

Powering IoT Modules Using Solar Panels, SuperCapacitors, and an Automatic Buck/Boost Controller IC Written By: Ron Demcko | Ashley Stanziola | Daniel West Abstract: The use of IoT modules is exhibiting a high rate of growth because of their low cost, ease of implementation, and easily documented impact upon end-user efficiency, reliability, and cost. Manufacturers, installers, and end-users of IoT modules are seeking ways to power these devices and essentially create a set-and-forget module. Set-and-forget means a significant ongoing effort to eliminate batteries or extend the life of batteries powering IoT modules. Manufacturers of IoT modules are working to reduce their designs’ power consumption and also working with IC suppliers by requesting novel chipsets to provide quality power from harvested
Capacitor Reliability Virtual Seminar | TJ Green Associates, LLC December 1st & 2nd, 2020 | 12 – 2 PM EDT The course is intended for component engineers, designers, process engineers, QEs, and managers responsible for designing and building hardware and procuring capacitors for use in microelectronic assemblies. Ron Demcko, AVX Fellow, will cover a wide range of technologies ranging from ceramic to film, stacked modules and SuperCapacitors. Students will gain an understanding of each capacitor technology ranging from construction, electrical performance and reliability. Performance characteristics are discussed relative to time, temperature, voltage and frequency. Distinctions are made between thin film capacitors and power film capacitors. Stacked capacitor modules – traditionally MLCC based are presented. SuperCapacitor technology is reviewed and
