Film safety capacitors provide economic noise suppressionMar 30 2005 - Passives [More Passives Articles]
A new range of radial leaded interference suppression film capacitors has
been launched by NIC Components Europe. The NPX series has safety agency
approvals from numerous bodies including UL and CSA. All parts from the
range are lead (Pb) free and fully RoHS compliant.
The devices have a metallized polypropylene moulded box construction and a
specification that includes ´X2´ across-the-line (250VAC / 275VAC) rating. A
capacitance range of 1000pF to 1uF and an operating temperature range
of -40C to +100C helps designers find a suitable part for most applications,
says the company.
With its non-inductive self-healing construction the NPX series offers
improved safety compared to ceramic alternatives. Metallized polypropylene
film capacitors also typically provide a more economical solution to EMI
noise suppression than ceramic devices.
In addition to UL and CSA certification, the range has VDE, SEV, SEMKO,
NEMKO, DEMKO, FIMKO and CE approval.
Typical applications for NPX series capacitors exist in products such as
power supplies, power management circuits, power invertors, voltage doublers
and AC/DC converters. Parts can be supplied on tape for high-speed insertion
to help reduce PCB assembly costs.
