Type 418P capacitors are wound from the most reliable polyester film and alum- inum foil available and are protected by a rugged conformal coating of orange epoxy. They may be operated up to +125C with proper derating. The 418P series finds use in many commercial and industrial applications, from power supplies and audio amplifiers to welding equipment and ultrasonics. Operating Temperature Range: Humidity Testing: The standard operating temperature range for Units subjected to 95% relative humidity for 72 polyester film is -55C to +85C. The 418P hours with no voltage applied at +75C. After 4 may be operated at full voltage within this hours of drying minimum product of insulation temperature range. resistance and capacitance shall be 5,000 M -F The 418P may be operated up to +105C provided the DC working voltage is reduced DC Voltage Life Test: to 70% of the +85C rating (full rating), and 500 hours at +85C at 150% of rated voltage. After up to +125C with a 50% reduction from the +85C rating (full rating). test capacitance shall not have changed by more than 5% of initial value, insulation resistance shall For more specific details regarding operation not have decreased by more than 50% of initial value above +85C please contact our design and dissipation factor shall not have increased to engineering department. more than 1.0%. In addition, there should be no The maximum operating temperature for the open or short circuits, and no sign of visible damage. 418P polyester film capacitor is +125C. Typical Temperature Characteristics: Dielectric Withstanding Voltage: Units rated below 1000 VDC shall withstand a DC potential of 250% of rated voltage applied between terminals for not more than 5 seconds. Units rated at 1000 VDC shall withstand a DC potential of 200% of rated voltage applied between terminals for not more than 5 seconds. Lead Bend Test: After 3 consecutive 180 bends. No damage.
