SFSWG & SFSWR EMI Panel Filters

Syfer / Knowles SFSWG and SFSWR Electromagnetic Interference (EMI) Panel Filters are feedthrough capacitors featuring a hermetic glass seal with a flange end. These Syfer / Knowles EMI panel filters offer a 10pF to 33nF wide capacitance range and voltage ratings of 100V, 200V, and 500V. The SFSWG and SFSWR provide high insulation resistance of 10GΩ or 1000ΩF and a wide operating temperature range of -55°C to +125°C. Applications include EMI suppression, medical imaging equipment, military communication devices, and high-reliability power and signal lines.
