New Yorker Electronics now offers two new Electrocube High-Temperature Film Capacitors for use in very high-temperature applications. The Electrocube 433D and 463D Foil Capacitor series are produced using PTFE or Teflon for maximum protection against extreme heat. The 433D Series is Teflon and Foil, while the 463D Series is Metallized Teflon.
The devices are specifically designed and optimised for high-temperature applications subjected to AC and pulsing signals. They are rugged, non-inductively wound film and foil capacitors with a high-temperature outer wrap and an epoxy endfill that meets or surpasses the flammability specifications of UL94V0. They are manufactured with proprietary processes that provide for successful usage in high-temperature environments. It offers high-frequency operation, high current and stability in a miniature package capable of handling high surge currents without degrading. The 433D series is wanted for its high-grade materials, design and manufacturing for employment in extremely high-temperature applications such as avionics, high power applications, wind generation, underground exploration and turbines.
These two new series are created with an extended electrode construction and standard tin-coated, oxygen-free solid copper leads and most units are offered in RoHS and Non-RoHS. The 433D is constructed with tolerances of ±5%, ±10% and ±15%; the 463D series has tolerances of ±5%, ±10% and ±20%.
They can be employed for frequencies up to 100kHz and have a temperature range of -55C to +150C without derating. These film capacitors are shown to withstand 150% of DC rated voltage (for a period not exceeding one minute at a temperature of 25C) and possess a current limited to 5mA. They will withstand 140% of the DC-rated voltage at 150C for 250 hours with not more than one failure in 12 permitted. The dissipation factor will not exceed 0.1% at 25C, and the dielectric absorption will not exceed 0.02% at 25C per MIL-C-19978.
