Capacitor polypropylene X2 1µF 22.5mm — safety interference suppression

Polypropylene X2 1µF 22.5mm — safety interference suppression capacitor intended for across-the-line connection in AC mains circuits where X2 safety class is required. The capacitor uses a polypropylene dielectric to provide stable capacitance and low dielectric losses, improving suppression of EMI/RFI noise. Its 1µF capacitance and 22.5 mm lead/body dimension suit installations in consumer appliances, power supplies and industrial equipment that require mains interference suppression and compliance with safety standards for class X2 capacitors.

Advantages

This polypropylene X2 capacitor delivers stable electrical characteristics across a range of temperatures and frequencies, with low dissipation factor for reduced self-heating. The X2 safety classification ensures the component can be connected across the mains without causing hazardous failures. The 22.5 mm dimension facilitates mounting in standard PCB or chassis layouts while maintaining required clearances for safety. Overall, the design emphasizes reliable noise attenuation, long-term stability and compatibility with common mains suppression circuits.

Suitable for

• EMI/RFI suppression across the AC mains in consumer appliances
• Across-the-line interference filtering in power supplies and chargers
• Main suppression networks in industrial control equipment
• Retrofit or replacement in circuits requiring X2 safety class capacitors

Key specifications

• Dielectric material: polypropylene
• Capacitance: 1 µF
• Safety class: X2 (across-the-line mains suppression)
• Dimension (lead/body): 22.5 mm
• Intended application: EMI/RFI mains interference suppression
• Electrical behavior: low dissipation factor, stable capacitance over frequency

How to use

Install the capacitor across the live and neutral conductors in the mains input stage where across-the-line suppression is required, observing correct polarity is not applicable for polypropylene film capacitors. Ensure the component is mounted with the specified 22.5 mm spacing and secured to maintain required creepage and clearance distances for safety. Verify that the surrounding circuit and housing meet regulatory requirements for X2 class components and that the capacitor is not exposed to environments outside its rated temperature and humidity ranges.

Usage recommendations

Select the capacitor only for applications explicitly requiring X2 safety class across-the-line suppression; avoid using it in circuits where Y classifications or safety-rated connections to earth are mandated. During assembly, follow manufacturer and safety standard guidelines for soldering temperatures and mechanical stress to preserve the dielectric integrity and safety characteristics.
