The FN751X AC Feedthrough Capacitor offers high insertion loss across a broad frequency range, from tens of kHz up to the GHz region. Its construction provides superior suppression performance compared to conventional two-wire capacitors. Designed for up to 300 VAC 50/60 Hz operation, these capacitors feature very low internal series inductance, a high self-resonant frequency, and a self-healing dielectric, ensuring high quality and reliability. They are suitable for through-bulkhead mounting with anti-twist protection. Custom-specific or dual-versions are available upon request.
