New Yorker Released Two Electrocube High Temperature Film Capacitors

Electrocube 433D & 463D Series Manufactured with Teflon® for use in Extremely High Temperature Applications


NORTHVALE, New Jersey, USA – New Yorker Electronics has announced the release of 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 specially 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. They are manufactured with proprietary processes that allow for successful use in high temperature environments. Made in the U.S., it offers high frequency operation, high current and stability in miniature package able to handle high 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-percent of DC rated voltage (for a period not exceeding one minute at temperature of 25°C) and possess a current limited to 5mA. They will withstand 140-percent 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 through New Yorker Electronics, including units with a higher IR or lower DF. Additionally, dimensional variations for all manufactured values that are available with the same volume.
