SFDP range of threaded panel mount EMI Filters
The SFDP range of feed-through EMI filters provides high current capability and impressive insertion loss over a wide frequency band, thanks to the high capacitance values available. With an M8 thread, they are supplied as standard with nuts and washers.
Available as standard in a Pi configuration version and are also available in 'C' and L-C configurations on request.
Current rating is 20A, voltage ratings from 50V to 1000V and capacitance values from 9.4nF to 940nF.
General threaded EMI filters range from M2.5 to M8, with UNC UNF and UNEF alternatives, in 'C' section, L-C, 'T' and pi-section. Hexagonal and round body styles are available, to suit a wide range of applications including aerospace, communications and microwave modules.

At the heart of every Knowles Syfer Brand resin sealed ceramic filter is a multilayer ceramic element, 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. Capacitance values up to 6.6µF are offered, with working voltages up to 3kVdc.

Special types include X2Y panel mount filters and we are always pleased to consider custom types such as form factor, lead length and varistor.
Resin Sealed Ceramic M8 X 0.75 - 6g thread, Pi section, 10mm hex head.
