Signal Transformer Announces High Current Toroidal Choke (HCTC) Design Kit Now Available

Features 15 of the Most Popular HCTC Part Numbers

Lynbrook, NY
[November 12, 2020] Signal Transformer, a Bel group company (NASDAQ: BELFA and BELFB) and global manufacturer of custom and standard transformers, chassis and PCB mount, high-frequency chokes and inductors, SMD inductors and wireless charging coils, announces their High Current Toroidal Choke (HCTC) Design Kit, featuring 15 of their most popular HCTC part numbers in a single, compact package, enabling engineers flexibility during their design selection process, with multiple options to choose from.

The HCTC Series of toroidal chokes feature a solid carrier base for stable vertical PCB mounting and fixed pin spacing for easy PCB insertion, high current capacity and excellent EMI suppression. Utilization of the largest possible conductor size for reduced heat rise and selection of low loss core material ensures high efficiency in a small package, while maintaining a competitive cost for the industrial, electronic, telecommunications, power and electric vehicle (EV) industries.

The HCTC Series Design Kit features a wide range of inductances and currents, with part numbers ranging from 1 mH, 4.8 A up to 50 mH, 2.3 A and 14 different DC rated currents. To learn more, visit the product page here or download the HCTC Series datasheet here.

The HCTC Design Kit will be available through our distribution network via Digi-Key and Mouser. Custom versions are also available upon request. For technical inquiries, call Signal at 866-239-5777, visit or email
