Tech Notes

Military Specifications Primer

Filters and Capacitors, Radio Frequency Interference, General Specification

All TSE products are designed and manufactured to the general requirements of 15733. All products are tested to Group A as applicable. Other testing is available on request.

Test Methods for Electronic and Electrical Component Parts

15733 specifies MS202 for most test methods. To successfully test a part, a test requirement, usually contained in the top document and a test method are required.

Method of Insertion Loss Measurement

15733 specifies MS220. MS220 specifies full load measurements between 100KHz and 20MHz. For AC rated parts, MS220 specifies using the DC equivalent of the peak AC current.

Requirements for the Control of Electromagnetic Interference, Emissions, and Susceptibility of Subsystems and Equipment.

461 is requirement levels for systems and equipment (not filters). See TSE Tech Note 1106PZ.

Filters and capacitors, RFI / EMI, General Specification

This specification is like 15733 except 28861 is for parts using ceramic capacitors and has established reliability levels.

Inspection System Requirements

This specification is used as TSE Quality Specification along with TSE Quality Assurance Procedures QA7000.

Tin Plating, Electro Deposited or Hot Dipped

TSE uses Type I, Electro deposited with 3% minimum lead. As part of the process, TSE parts are hot oil fused after plating. The minimum lead content prevents tin 'whiskers'.
