Now available through New Yorker Electronics, the new Exxelia Dearborn 880P
Series of metalized Polyphenylene Sulfide (PPS) film capacitors is designed
to keep cool when things get hot. With an operating temperature range of
-55C to +150C, they experience no derating for DC operations and none in AC
operations up to +125C. This enables them to function at full capacity in
extreme heat applications. The ability to operate at such high temperatures
can eliminate the need for a cooling system within the design, thus reducing
overall design time, weight and space.
PPS is a high-temperature, low-loss dielectric film used in the 880P Series
of wrap-and-fill capacitors. This allows them to feature superior electrical
characteristics over an extremely wide temperature range and maintain
excellent capacitance stability in one rugged, lightweight package. It
performs consistently well in commercial applications such as in power
supplies and in more demanding applications, such as in avionics, on a
congested control or instrumentation panel.
The series features a capacitance range of 0.0047µF to 10.0µF and voltage
ratings from 50 to 400VDC with precision tolerances as low as ±¼% through
±10% yielding greater accuracy of capacitance.
The parts are highly durable and capable of withstanding a five-pound pull
force on lead axis. They are non-polar and demonstrate low loss factor, good
voltage breakdown strength and high insulation resistance (low leak current)
-- and are completely stable over normal temperatures, voltages and
frequency ranges. These characteristics allow the 880P Series capacitors to
deliver high performance in a variety of applications such as DC timing
circuits, low- to high-frequency AC applications, and pulse or energy
discharge uses.
Additionally, the package has axial leads with moisture-resistant,
flame-retardant epoxy end seals and an outer tape covering for maximum
performance, says the company.
