Product Overview
The FN761X series are AC feedthrough filters designed for high EMI suppression across a broad frequency range, offering a higher level of performance than feedthrough capacitors of the same current rating. They are ideal for applications with low source impedance, providing through-bulkhead mounting with anti-twist protection. Available in various current ratings and performance levels, these filters are approved for up to 300 VAC 50/60 Hz operation.
