Noise Suppression & Safety Capacitors:

2,370 Products Found

element14 offers a comprehensive selection of noise suppression safety capacitors, essential for filtering electromagnetic interference (EMI) and radio-frequency interference (RFI) in electronic devices and power circuits. Designed to meet stringent safety standards, these capacitors are ideal for safeguarding equipment connected to AC power lines.

Our range includes Class-X and Class-Y capacitors, built specifically for noise suppression in critical applications. Class-X capacitors, positioned between line and neutral, help manage overvoltage by directing unwanted surges safely across the line, thereby protecting sensitive circuitry. Class-Y capacitors, used between line and ground, are crafted to fail open, reducing the risk of electrical shock and enhancing safety in case of high transient voltages.

These high-performance capacitors are essential in applications like household appliances, industrial controls, and power tools. With options covering different capacitance values, voltage ratings, dielectric type such as metallized PP/PET/Paper and safety certifications, element14’s noise suppression capacitors deliver robust protection, circuit stability, and enhanced reliability for equipment operating in EMI-prone environments.
