KEMET Paper Capacitor X2 330nF 275V AC 275V DC Through Hole PME271

The KEMET PME271M633KR30 is a paper film capacitor engineered for X2 suppression applications, designed to be connected directly across a mains supply. Featuring a 330nF capacitance, this capacitor offers exceptional safety and reliability owing to its metallised paper construction, which provides both active and passive flammability resistance.

This component is rated for operation at up to 275V AC or 275V DC, making it highly suitable for filtering and suppression applications in power electronics, industrial automation, and consumer devices. The PME271M633KR30 is compliant with international standards including IEC, CSA, EN, CAN, and UL, ensuring its suitability for use in global electrical systems. Its maximum operating temperature of 110°C allows use in challenging thermal environments.

The capacitor employs a through hole mounting configuration and provides a lead pitch of 25.4mm, enabling straightforward integration onto printed circuit boards. With compact dimensions (30.5mm × 19mm × 12.1mm) and a pin count of two, it fits well in densely populated electronic assemblies. The encapsulation meets UL94-0, offering additional safety through high flammability resistance.

Notable for its high dV/dt capability and excellent self-healing properties, the PME271M633KR30 ensures a long lifespan even under frequent over-voltage conditions. This makes it a dependable choice for power supplies, industrial controllers, and EMI/RFI suppression scenarios. Its X2 suppression class designation confirms its use in installations where voltage transients may occur but must not exceed 250V RMS continuously.

Common applications include industrial automation panels, consumer mains-powered devices, power management circuits, and switching-mode power supplies. The device’s metallised paper dielectric offers a unique combination of high safety margins and resilience against electrical stress, highly valued in critical circuitry where safety and compliance are paramount.

The product is manufactured in Finland, further underscoring its adherence to stringent quality and safety standards. The PME271M633KR30 is part of the PME271 series, renowned for consistent performance in demanding applications.
