Film capacitors supply ultra-stable performance
New Yorker Electronics has released Exxelia’s new 253P Series of Wrap-and-Fill High Temperature PTFE Film capacitors.
The PTFE capacitor is the most stable 200°C Film capacitor on the market with stability of less than 2.5% with capacitance from 0.22μF to 1μF under 250VDC to 800VDC.
It offers the lowest loss characteristic of all film technologies less than 0.1% at extreme temperatures (200°C) with excellent life performance in operations.
The series offers great resistance to vibrations, shocks and to over voltage making it ideal for Oil & Gas applications as well as Defence and Civil Aviation.
Made in the USA, it boasts rugged, lightweight construction.
These non-inductive wound PTFE metallised polymer film capacitors are available in voltage ranges from 250VDC to 800VDC and in capacitance ranges from 0.22μF to 1μF.
They come in standard tolerances of ±10% and ±5% and operate at temperatures between -55°C and 200°C.
These wrap-and-fill capacitors are constructed with non-Inductive wound PTFE metallised Polymer film in a flame retardant tape wrap and high-temperature resin end fill.
Lead material for PTFE less than 600V PTFE uses insulated silver stranded copper wire and uses MIL-W-16878/4 (Type E) wire for those greater than 600V.
It is capable of withstanding a five-pound pull force on lead axis.
PTFE is the only film able to preserve its properties beginning from cryogenic temperature up to 200°C, making it suitable for high-temperature sampler-blocker and stopping sampler applications.
Polystyrene (PS) capacitors are perfect as precision capacitors for time constant and filter applications in aeronautics, defence, rail, telecom and medical fields.
