Polypropylene X2 Safety Capacitor 0.68µF 22.5mm diameter

Polypropylene X2 Safety Capacitor 0.68µF 22.5mm diameter is a film-type capacitor intended for across-the-line (X2) interference suppression in mains-connected equipment. It provides a capacitance of 0.68µF with a compact 22.5 mm diameter footprint and uses a polypropylene dielectric that delivers low loss, stable electrical characteristics and good self-healing properties suitable for AC mains environments. The component is designed to meet the functional requirements of X2 safety class applications where suppression of EMI/RFI and transient noise is required while maintaining safety separation from live circuits.

Advantages

This polypropylene X2 capacitor offers low dissipation factor and stable capacitance over a wide temperature range, reducing insertion loss in filter circuits. Its polypropylene dielectric provides low dielectric absorption and predictable behavior under AC stress, improving long-term reliability in power supply and motor-drive EMI suppression. The compact 22.5 mm diameter enables installation in constrained PCB or module layouts while preserving the required safety clearances for across-the-line use.

Suitable for

• EMI/RFI suppression in mains filters
• Across-the-line suppression in power supplies and inverters
• Motor run and control circuitry requiring interference suppression
• Household appliances and consumer electronics with X2 safety class requirements

Key specifications

• Capacitance: 0.68 µF
• Dielectric material: polypropylene film
• Safety class: X2 (across-the-line applications)
• Physical diameter: 22.5 mm
• Suitable for AC mains voltages and interference suppression circuits
• Low dissipation factor and low dielectric absorption

How to use

Install the capacitor across the live and neutral lines of the mains input or across the points where suppression is required according to the circuit design and safety regulations. Ensure correct PCB spacing and mounting to maintain the safety isolation expected of X2 class components. Verify polarity is not applicable for polypropylene film capacitors, and secure lead connections or solder joints to avoid mechanical stress. Confirm that the capacitor is rated for the mains voltage and environmental conditions of the application before commissioning.

Usage recommendations

Use this X2 polypropylene capacitor in filter networks where low loss and stable AC performance are needed. Follow applicable safety standards for mains-connected components, provide adequate creepage and clearance on the PCB, and avoid exposure to temperatures or mechanical stresses beyond the capacitor's rated limits to ensure reliable operation.
