The Electrocube 744B series is part of a designated line of film capacitors specially designed and optimized for high current applications subject to AC and pulsing signals. This film capacitor series offers high frequency operation and stability in a miniature package able to handle high surge currents without degrading. It’s a rugged, non-inductively wound metallized capacitor with flame-retardant polyester outer wrap and flame- retardant epoxy endfill. Manufactured with design expertise and high-grade materials, engineers prefer the 744B series for any high current applications such as avionics, wind generation and other high power applications.
