The snap-in type capacitors are normally used for higher-end LED applications such as street lighting. EPCOS offers three categories as shown on this slide. In the 85ºC class the B41231 is rated at 10 to 100 VDC and has a useful life of more than 2000 hours. The standard series, B41252, has a voltage range of 10 to 100 VDC and a useful life of more than 2000 hours at the rated temperature of 105ºC. For a much longer life solution, the B41505 has a voltage range of 10 to 100 VDC and a useful life of more than 2000 hours at the rated temperature of 105ºC.
