AMPOHM WOUND PRODUCTS FE-SP-HDR Contact Suppressor 0.1uF 47R

The AMPOHM WOUND PRODUCTS FE-SP-HDR Contact Suppressor is a high-performance, class X2-rated capacitor designed to suppress electrical contact arcing and reduce electromagnetic interference (EMI) in a wide range of industrial and commercial applications. Its combination of a 0.1µF capacitance and a 47-ohm series resistor makes it highly effective for protecting contacts from wear and prolonging the operational life of switches, relays, and contactors.

Housed in a robust, radial box package, this suppressor is built for reliable through-hole mounting on printed circuit boards. It is rated for 250V AC, ensuring safe operation in typical mains-level applications. The component features a broad operating temperature range from -40°C to +85°C, guaranteeing stable performance in challenging environmental conditions, from cold storage facilities to hot industrial control panels.

Key Features & Benefits

• Arcing Suppression: The RC (Resistor-Capacitor) network effectively dampens voltage spikes and reduces contact arcing, minimising electrical noise and preventing premature contact failure.
• EMI Reduction: Helps to limit electromagnetic interference, improving the overall electromagnetic compatibility (EMC) of your electronic systems and preventing interference with nearby sensitive equipment.
• Extended Component Life: By protecting mechanical contacts from excessive wear and pitting caused by arcing, this suppressor significantly extends the service life of relays and switches.
• Robust Construction: The component features a lead spacing of 22.5mm, facilitating easy board insertion and soldering, and is designed for long-term reliability.

An essential component for electrical engineers and maintenance professionals, this contact suppressor is a cost-effective solution for enhancing system reliability, meeting EMC standards, and reducing maintenance costs associated with contactor/​
