Box PF 275V0.22uF (White-NP) (27*15*6) (X2 Class PF Capacitor) Code: 36912981

A 275V 0.22µF capacitor is a standard X2-class metallized polypropylene film safety capacitor designed to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) across AC mains. It is widely used in power supplies, appliances, and industrial controllers for noise filtering and transient voltage absorption.

Key Specifications

• Capacitance:22 μF (or 220 nF, often coded as 224 or 224K)
• Voltage Rating:275V AC (suitable for standard 120V to 240V AC mains)
• Safety Class:Class X2 (designed for applications where failure would not lead to electric shock, handling voltage spikes up to 2.5kV)
• Dielectric Material:Metallized Polypropylene (MKP)
• Tolerance:Typically ± 10% (marked with a ‘K’ at the end of the code, e.g., 224K)
• Operating Temperature:Typically -40°C to +100°C or +110°C
• Physical Dimensions:Usually radial box type, with a lead spacing (pitch) commonly between 15 mm to 22.5 mm

Important Notes

• Safety First:X2 capacitors are “self-healing,” meaning they vaporize minor internal faults to prevent short circuits. However, if you are replacing a faulty one, always ensure the replacement matches the X2 safety rating. Standard non-safety film capacitors will fail as a fire hazard under AC mains conditions.
• Non-polarized:These capacitors do not have a positive or negative terminal, allowing them to be installed in either direction.
