EMI filter approved for space programme

The bolt style, resin sealed, C-circuit filter from the company’s 640 Series will now be used for a US government space programme where it will help suppress electromagnetic interference, which would otherwise interfere with the performance of electronic circuitry.

The specific part number is Instec 640-102CN. Performance includes Capacitance of 1,000 pF minimum, DC voltage rating of 100V and current rating of 5A DC. Typical insertion loss is 8dB at 10MHz, 25dB at 100MHz and 40dB at both 1GHz and 10GHz. The Operating Temperature Range is -55°C to 125°C. This part is thread type 8-32 and consists of a silver plated brass case and silver plated copper nail head lead.

The mil-spec qualification of this part required rigorous testing of electrical, thermal and mechanical properties. Testing was performed at Gowanda’s in-house environmental lab. This lab is Defense Logistics Agency Land and Maritime approved (in support of internal product qualifications).

Instec is open to enquiries regarding the upscreening of additional filters for applications in defence, military and space communities. The company also supports custom designs with extensive experience, proprietary manufacturing equipment, prototyping capabilities and testing facilities.
