SMS : Polypropylene Capacitor: 700Vdc - 1800Vdc

Product description

The SMS range of capacitors has been designed to offer electronic circuit designers of dc filtering applications an alternative to electrolytic capacitors. Manufactured from a special metallised polypropylene film, the component offers a very high volumetric efficiency and current handling capability.

The design has particularly good self healing capabilities and is able to with stand high overvoltage stresses without becoming short circuit.

The design also affords extremely low self inductance. The capacitors are housed in a UL 94-V0 rated plastic case.

Expected life

Quality and useful life

The specification of quality data - which always refers to a fairly large number of components - does not constitute a guarantee of characteristics or properties in the legal sense. However, agreement on the specifications does not mean that the customer may not claim for replacement of individual defective components within the terms of delivery. We cannot, however, assume any further liability beyond the replacement of defective components. This applies in particular to any further consequences of component failure.

Furthermore, it must be taken into consideration that the figures stated for useful life and failure rate refer to the average production status and are therefore to be understood as mean values (statistical expectations) for a large number of delivery lots of identical capacitors. These figures are based on application experience and data obtained from preceding tests under normal conditions, or - for purposes of accelerated aging - more severe conditions.
