Vishay Single Layer Ceramic Capacitor 2.2 nF 400V ac ±20 % Y5U Dielectric Through Hole Radial Lead WYO222MCMBF0KR

Vishay WYO222MCMBF0KR Single Layer Ceramic Capacitor is a through hole radial lead device with a capacitance of 2.2 nF and an AC voltage rating of 400 V. It utilizes the Y5U type dielectric material, allowing for stable capacitance over a temperature range from -40 °C up to a maximum operating temperature of 125 °C. The capacitor is part of the WYO series, known for high reliability and conformity to IEC 60384-14 3rd edition safety standards.

The capacitor is constructed with ceramic discs silver plated on both sides and coated with a flame retardant blue epoxy resin to meet UL 94 V-0 requirements. Its design includes tinned copper leads of 0.6 mm diameter, available with either straight or kinked forms, and lead spacing of 5.0 mm or 7.5 mm, providing installation flexibility on printed circuit boards.

This product is suitable for industrial and commercial electronic applications requiring line-by-pass or safety suppression capacitors, especially as X1 or Y2 class capacitors according to IEC 60384-14. It carries approvals from UL and CSA agencies, ensuring its safety and performance standards are met.

Typical applications include power supply filtering, AC line noise reduction, and protection circuitry in electronic equipment under demanding environmental conditions. This capacitor delivers consistent performance even in high temperature environments up to 125 °C.

Its radial through hole mounting method offers robust mechanical stability for industrial PCB assemblies. The Y5U dielectric provides a cost-effective capacitance solution with ±20 % tolerance for general purpose AC applications.

Compliance with international safety standards supports use in globally distributed electronic products. The flame retardant coating enhances durability and safety in potentially harsh operating conditions.

With Vishay’s reputation and the WYO222MCMBF0KR model precision, this component is a reliable choice for engineers designing AC line filtering and suppression circuitry in industrial, telecommunications, and consumer electronics domains.
