NEW X2 INTERFERENCE SUPPRESSION FILM CAPACITORS FEATURE CAPACITANCE VALUES
07 December 2003 - Vishay Electronic

Vishay Intertechnology, Inc. today announced the release of a new series of compact, lead (Pb)-free electromagnetic interference suppression film capacitors that combine a wide range of capacitance values with pitch sizes down to 7.5 mm. Ideal for filters, power supplies, and mains applications, capacitors in the Vishay BCcomponents 339 X2 series have IEC 60384-14 (2nd edition) and EN 132400 approvals for X2 suppression.

The new 339 X2 series offers capacitance values ranging from 0.001 µF to 4.7 µF with tolerances rated at either ±10% or ±20%. Case sizes at many capacitance values are smaller than those of previously available devices, while the height of 339 X2 series capacitors with values greater than 100 nF is lowered by between 1 mm and 2 mm. As a result, the capacitors will be especially useful in applications where board space is limited and mounting height is restricted. Lead pitch for the capacitors ranges from 7.5 mm to 27.5 mm.

Capacitors in the 339 X2 series are constructed using a low inductive wound cell of metallized polypropylene film potted in a flame-retardant case made of material that is qualified in accordance with UL94V-O. Maximum operating temperature for the components is 105 °C.

All of the new devices have a rated voltage of 275 V AC at 50/60 Hz, with maximum permissible dc voltage specified as 630 VDC. The capacitors can be supplied loose in a box or taped in ammopack or reel format.
