ECK-THC221KB Description

Short technical summary and product information.

The Panasonic ECK-THC221KB is a surface mount ceramic capacitor designed for safety-critical interference suppression and isolation circuits. It features a Y1 safety classification, ensuring reliable operation in line-to-line and line-to-ground applications.

 

With a nominal capacitance of 220pF and a tolerance of ±10%, this capacitor is rated for 250VAC operation. The Y5P dielectric provides a temperature coefficient of +350 to -1000 ppm/°C over -25°C to 85°C. It offers a dielectric withstanding voltage of 1500VAC for 1 minute and a minimum insulation resistance of 10000 MΩ at 500VDC.

 

The component is housed in a resin molded 2-SMD package with gull wing leads, suitable for reflow soldering. Dimensions are 6.80mm × 4.50mm with a maximum thickness of 2.50mm. It is approved by UL, SEMKO, NEMKO, FIMKO, DEMKO, and KTL for safety applications.
