Two new series of robust EPCOS Aternating Current (AC) capacitors have been introduced by TDK Corporation. 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 4500VAC (50/60Hz) and the permissible operating temperature is between -40 and +85°C. This results in life expectancy of 30,000 hours.
The B33331 series covers a capacity range from 2 to 50µF. Depending on the capacity, the dimensions range from 30x5mm to 50x100mm. 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 + 1.5 and 60 + 8µF. The dimensions range from 50x57mm to 63.5x102mm.
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.
