Datatronics Romoland is a world leader in transformers and inductors for equipment supporting a wide range of aerospace, avionics, military, medical, telecommunications and portable device applications. The company designs and manufactures standard and custom magnetic components: power inductors, RF magnetics, switching transformers, telecom transformers, high-voltage transformers, LAN modules/filters, and fine-wire magnetics as small as 56 AWG.

Gowanda Electronics offers the industry’s first off-the-shelf Shielded RF Surface Mount (SMT) Inductors with established reliability (ER) ratings. This Gowanda ER5025S series compliments MIL-PRF-39010 QPL axial-leaded (thru-hole) products, and enables their conversion to SMT circuitry. These wirewound, molded, shielded inductors are designed for RF applications in military, aerospace and space markets, communication, guidance, security, radar, test and evaluation, and special mission applications.

This Ka-Band active waveguide limiter allows the system direct control over when the limiting function is applied. Built In Test Equipment (BITE) indicates a short circuit RF diode when blanking.
The D124C Series surface mount fixed inductor is a low profile, shielded inductor for use as a DC choke coil
