Interference suppression capacitors suited to extreme operating conditions
Würth Elektronik has released the WCAP-FTXH THB X2 series, its new family of safety Capacitors for interference suppression in mains filters. All pieces in this series are ENEC 10, cULus, and CQC certified and belong to the X2 safety class capacitors according to IEC 60384-14. What makes the capacitors, designed for 310V rated voltage, particularly special is the resistance to heat and moisture. They, therefore, pass a 1000-hour test at 85C and 85% relative humidity with the rated voltage applied. Their operating temperature range covers -40C to +110C.
The family of capacitors has self-healing properties thanks to its polypropylene dielectric. If a short circuit arises in the component, it eliminates its cause by vaporising the defect, thus restoring an intact dielectric.
The film capacitors are offered in 21 variants with varying capacitance values (from 33nF to 10µF), voltage ramp-up rates, and insulation resistances. The components are provided in different sizes depending on their values and a pin pitch from 15mm to 37.5mm.
