Robust AC capacitors have complete aluminum housing

07-09-2016 | TDK | Passives

TDK Corporation have two new series of robust EPCOS alternating current (AC) capacitors. Both the cans and the tops of the components are constructed of aluminium, making them particularly robust. All capacitors in the B33331 and B33335 series are CE-compliant, have both VDE approval in accordance with EN/IEC 60252-1 Class A and UL approval. Thanks to their robust design and integrated overpressure disconnector, the capacitors meet the requirements of safety class S2 as specified by EN/IEC 60252-1. The rated voltage for all the new types is 450V AC (50/60Hz) and the permissible operating temperature is between -40C and +85C. This results in life expectancy of 30,000 hours. The B33331 series covers a capacity range from 2µF to 50µF. Depending on the capacity, the dimensions range from 30mm x 55mm to 50mm x 100mm (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 12µF + 1.5µF and 60µF + 8µF. The dimensions range from 50mm x 57mm to 63.5mm x 102mm (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.
