Threaded panel mount EMI filters

Syfer threaded EMI filters range from M2.5 to M6, with UNC and UNF 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 Syfer 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 2.2µF are offered, with working voltages up to 3kVdc.

Special types include X2Y panel mount filters and varistor filters, and we are always pleased to consider custom types.
