Hermetically Sealed Panel Mount EMI Filters

The SL range of ceramic based filters represents an extension to our SF range of filters with the added features of hermetic construction, wound coil inductors and iron powder cores for improved high current performance. Electrical configurations include 'C', 'L-C' and Pi-section, with current ratings up to 100A.  With working voltages up to 450Vdc, the maximum capacitance is 2.8µF.

At the heart of each filter is a multilayer ceramic discoidal capacitor, manufactured using our unique 'Wet Process'. Dielectric materials used include the ultra stable C0G and stable X7R types - Z5U/Y5V is not used. This ensures excellent insertion loss performance is provided up to full rated voltage and to the extremes of rated temperature.

Additionally, the range also includes a selection of filters designed and tested to meet the requirements of WE772 / DEF-STAN.59-45/90/013. These filters are particularly designed to suit the exacting requirements for protection of military and aerospace equipment, such as explosive devices, missiles and flight control systems. They will also be suitable for other rigorous applications and may meet the requirements of other military and aerospace specifications.
