This Würth Elektronik webinar discuss feedback loop compensation of current-mode flyback converter and optocoupler compensator. The Flyback converter with current-mode control is widely used in isolated applications below 150 W, in which an optocoupler transmits the output voltage feedback signal across the isolation barrier for regulation. The optocoupler is therefore part of the feedback loop […]

Digi-Key celebrates ribbon cutting of its US product distribution center expansion. The 2.2 million square foot facility makes Digi-Key one of the 10 largest warehouses in North America. Digi-Key Electronics, which offers the world’s largest selection of electronic components and automation products in stock for immediate shipment, celebrated the ribbon cutting of its Product Distribution

KYOCERA AVX Celebrates the release of its 1,000th TRAFIM series high-voltage power film capacitor for DC filtering applications. Since launching the series in 1990, KYOCERA AVX has manufactured more than 365,000 of the now-1,000 unique TRAFIM Series part numbers, all of which are widely renowned for their controlled self-healing technology, high energy density, and safe,

TDK Corporation presents the EPCOS E13EMHV series of compact SMD transformers with high dielectric strength for a wide range of DC-DC converter topologies. The isolation distances comply with IEC 60664-1, 61558-2-16 standard, achieving a high working voltage of 1000 V DC. Transient overvoltages of up to 2500 Vpeak are permitted. The high dielectric strength between the

This article written by Jeff Shepard discusses brief background on wire-wound inductors and then digs into the cost and application trade-offs associated with multilayer SMD thin and thick film inductors, flat inductors (including Litz wire with a rectangular cross-section), and foil inductors. Wire wound structures are the most common, but far from only, way to

This technical blog article written by Sudhama Dharmappa, KYOCERA-AVX Components Corporation, discusses ESD surge protection of Advanced Driver Assistance Systems (ADAS) by miniature multilayer varistors (MLV). Understanding ADAS Driver Assistance Systems Advanced Driver Assistance Systems (ADAS) have been used to enhance vehicle safety and performance long before the pursuit of self-driving cars. Since the moment electronic sensors

This article provides an overview of most common resistor technology and its selection guide. Resistance is one of the most basic concepts in electricity and electronics. And resistors are simple-looking devices. Given their apparent simplicity, the range of resistor types and their capabilities can be surprising. This article looks at some common resistor types and

Learn how critical items, such as package style selection, terminal selection, transformer calculation and winding order, are to the success of a transformer. The designer will take you through several iterations of

Researchers from Osaka Metropolitan University introduced new 300°C heat-tolerant, high-capacity lithium supercapacitor created with solid electrolytes borrowed from all-solid-state batteries. Capacitors are energy storage devices, consisting of two electrodes and an electrolyte, that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the electrode-electrolyte interface. Because capacitors’ energy storage
