New Yorker Electronics releases new Electrocube high temperature film capacitors

09 September 2021

New Yorker Electronics has released two new Electrocube high temperature film capacitors for use in very high temperature applications. Both the Electrocube 433D and 463D foil capacitor series are manufactured using polytetrafluoroethylene (PTFE or Teflon) for maximum protection against extreme heat. The 433D series is Teflon and foil while the 463D series is metallized Teflon.

The Electrocube 433D and 463 are designed and optimized for high temperature applications subject to AC and pulsing signals. They are rugged, non-inductively wound film and foil capacitors with high temperature outer wrap and an epoxy endfill, which meets or exceeds flammability requirements of UL94V0. The capacitors offer high frequency operation, high current and stability in miniature package able to handle Source: New Yorker ElectronicsSource: New Yorker Electronicshigh surge currents without degrading. The 433D series is coveted for its high-grade materials, design and manufacturing for use in any extremely high temperature applications such as avionics, wind generation, high power applications, underground exploration and turbines.

These two new series are designed with an extended electrode construction and standard tin-coated, oxygen-free solid copper leads and most units are available in both RoHS and non-RoHS. The 433D is built with tolerances of ±5%, ±10% and ±15%; the 463D series is available in tolerances of ±5%, ±10% and ±20%.

They may be used for frequencies up to 100 kHz and have a temperature range of -55° C to 150° C without derating. These Electrocube film capacitors are proven to withstand 150% of DC rated voltage (for a period not exceeding one minute at temperatures of 25° C) and possess a current limited to 5 mA. They will withstand 140% of the DC-rated voltage at 150° C for 250 hours with not more than one failure in 12 permitted. The dissipation factor will not exceed .1% at 25° C and the dielectric absorption will not exceed 0.02% at 25° C per MIL-C-19978.

Protective clear wrap are offered on all wrap and fill units. Customizable insulating sleeves, mountings, special terminals, non-standard leads, circuit connections and other hardware are also available. Assorted styles, ratings and customization for unusual requirements are offered, including units with a higher current resistance or lower dissipation factor.
