TTE Filters says that its Instec Filters brand ML61 EMI/RFI filters are now qualified to the US Department of Defense DLA Land and Maritime’s MIL-PRF-28861 military standard.

This series will be featured at the 2021 International Microwave Symposium in Atlanta on June 8-9.

This series can now be used in military electronic systems to suppress and reduce broadband radio frequency interference which would otherwise compromise system performance.

These high performance systems are utilised in military communication devices, oscillators, attenuators and low noise amplifiers.

The electrical characteristic ranges of these lowpass, feed-through, C-circuit, solder-in ML61 filters include Rated Voltage from 50Vdc to 200Vdc, Capacitance from 10pF to 15,000pF and Minimum Insertion Loss from 3dB to 60dB.

Operating Temperature is -55°C to +125°C.

The parts in this ML61 series are hermetically glass sealed at one end and epoxied at the other end, with the location of the glass seal dependent on the particular configuration. In conformance with the MilSpec, the company can provide these filters in Configuration A (ML610) or Configuration B (ML611).

The main body of each part in this series measures 0.128in. (3.25mm) in diameter while the main body height is 0.110in. (2.79mm) and the overall tip-to-tip length is 0.625in. (15.88mm).
