The previous tutorial in this series highlighted the performance, flexibility, and speed benefits of using power modules to design power systems then provided an overview of the modular design process. A modular design strategy is powerful, but it requires support circuitry in the power delivery network (PDN) to form a complete power system. This second […]

Miniature common mode filters combine wide differential bandpass with ESD protection
Nexperia, the expert in essential semiconductors, has announced its new PCMFxHDMI2BA-C, a combined, highly efficient, common mode filter and ESD protection device with the widest 10 GHz differential bandwidth. It is suitable for the latest HDMI 2.1 standard up to 12G FRL, where eye-diagram tests were passed even with “worst cable model”. This highly integrated PCMFxHDMI2BA-C device provides excellent common […]
Current-compensated dual choke filter inductors handle high currents
Bourns, Inc.introduced the Model DR334A Line Filter Series. These current-compensated dual choke filter inductors feature higher current capability than typical standard signal line common mode chokes, as well as high stray inductance and differential mode noise rejection. These capabilities make the Model DR334A series ideal line filter solutions for consumer, industrial and other market power […]

High-current noise suppression filters optimized for smart-speaker apps
TDK Corporation expanded the MAF series of noise suppression filters with two new MAF1608GAD-L types that are designed for audio lines. The new multilayer filters have a compact footprint of just 1.6 x 0.8 mm and an insertion height of just 0.6 mm and are able to suppress noise at cellular frequencies from 1 GHz […]
Common-mode choke coil for Automotive Ethernet handles 150 C temperatures
Murata Manufacturing Co., Ltd. announced that the DLW32MH201YK2, a common mode choke coil (CMCC) for Automotive Ethernet (100BASE-T1). Withstanding extreme temperatures ranging from -55 to +150ºC, makes this product a world first for its type. Mass production of this product will start in December 2019. In recent years, as cars have been equipped with more […]
EMC filters excel at high frequencies for SiC, GaN applications
SMP has developed “All Mode” EMC filters with high-frequency stability. The High-Frequency Composite Materials (HFCM) developed and manufactured by SMP are effective for frequencies up to the gigaHertz range and satisfy all of the requirements to which modern SiC and GaN applications are subject. The All Mode design damps both differential mode and common mode […]
Powerline EMI filters simplify compliance to MIL-STD-461G, MIL-STD-1275D and RTCA/DO-160G
The TDK-Lambda FQA series of EMC filters has a rating of ±40 Vdc at 20 A. The FQA has a rugged encapsulated quarter-brick package with a choice of flanged or non-flanged baseplates. These modules are suitable for use in a wide variety of harsh and demanding environments, including MIL-COTS vehicle and airborne applications. The FQA […]
