Robust AC Capacitors Last for 30,000 Hours

07 September 2016

TDK Corporation is offering two series of EPCOS alternating current (AC) capacitors. Both the cans and the tops of the components are constructed of aluminum, making them particularly robust. All capacitors in the B33331 and B33335 series are CE-compliant and have both VDE approval in accordance with EN/IEC 60252-1 Class A and UL approval.

The capacitors meet the requirements of safety class S2 as specified by EN/IEC 60252-1. The rated voltage for all the types is 450 VAC (50/60 Hz), and the permissible operating temperature is between –40° C and +85° C. This results in a life expectancy of 30,000 hours. The B33331 series covers a capacity range from 2 µF to 50 µF. Depending on the capacity, the dimensions for the B33331 range from 30 mm x 55 mm to 50 mm x 100 mm (d x h).

The B33335 series features two capacitors installed in one enclosure. With these double capacitors, different combinations of capacitance values are offered. The current standard range covers values between 12 µF + 1.5 µF and 60 µF + 8 µF. The dimensions range from 50 mm x 57 mm to 63.5 mm x 102 mm (d x h). The double capacitors are particularly suitable for use in air-conditioning systems, in which the larger capacitance is used for the compressor motor and the smaller capacitance for the fan motor.

Further capacitance and voltage values are available on request.
