Smaller safety capacitors

7 April 2004 Circuit & System Protection Information Security

Murata's revision of safety recognised leaded capacitors reduces the number of different types needed, increases mounting density and introduces what it says is the world's smallest class Y1 capacitors.

Values up to 680 pF remain unchanged, but from 1000 pF to 4700 pF diameters are reduced by up to 22% and weight by an average of 10%. All versions are recognised to the 6th edition of UL1414 in classes X1 and Y1. One version meets the requirements of both reinforced and double insulation protection for AV and office equipment.

Dielectric strength is 4000 V a.c. (rms) and the guaranteed operating temperature range is up to 125°C (UL/CSA 85°C). Temperature characteristics are unchanged, with values up to 680 pF having a maximum change of ±10% over the range -25 to 85°C and values from 1,0 nF having a characteristic of +20-55% over the same range.

The range is safety recognised by leading standards authorities. They can be used in applications requiring either reinforced or double insulation. The flame retardant epoxy resin conforms to UL94V-0.
