DSERIES METALLIZED POLYESTER CAPACITORS
ENGINEERING DATA SHEET and ENVIRONMENTAL DATA
Series D Metallized Polyester capacitors are superior general purpose capacitors for both AC and DC applications. They are dry-section, non-polar, non-inductive wound capacitors with high volumetric efficiency and a low cost.
Series D Capacitors come in several styles: Oval Wrap & Fill (DW Style), Round Wrap & Fill (DR Style), both in regular and new Flame Retardant Tape; Axial Epoxy Case (DE Style); Radial Epoxy Case (DF Style); Rectangular Hermetically Sealed (DG Style); Round Hermetically Sealed (DL Style); Round Wrapped Feed-Through (DQ Style). They are available in several sizes including Regular (3 Size code) and Miniature (2 Size code) as well as custom sizes to meet specific customer requirements.
Contact our Engineering Department for special sizes, configurations, capacitance values and AC applications with Anti-Corona construction at all frequencies. Custom metal enclosures are available. Custom designed Feed Through capacitors (DQ Style) are also available for filter applications to specific requirements.
OPERATING TEMPERATURE RANGE
Range: -55°C to +125°C, with voltage derating.
Series D capacitors shall be capable of withstanding a test of 1000 hours at +125°C and 100% of the derated DC voltage or a test of 250 hours at +125°C and 140% of the derated DC voltage. The voltage shall be applied to each capacitor through its individual current-limiting resistor as determined from the formula R = 0.025/C, where C is the nominal capacitance in farads and R is in ohms.
The test procedures shall be in accordance with MIL-C-18312, except as noted herein. Not more than one failure in twelve shall be permitted. Any one of the following shall be considered a failure.
Series D capacitors shall be capable of withstanding a vibration test in accordance with MIL-STD-202, Method 201. The following details and exceptions shall apply:
Series D capacitor Styles DG and DL (Hermetically Sealed in metal containers) as well as Metal Can Styles DB and DC shall be capable of withstanding the moisture resistance, humidity, and temperature and immersion cycling or MIL-C-18312. Styles DE and DF (Epoxy Case), Styles DW and DR (Wrap & Fill) and DQ (Feed-Through) capacitors are not intended for exposure to high humidity conditions over extended periods of time.
Series D capacitors utilize tin-plated, copper-clad steel wire terminals which shall be capable of withstanding the following test without mechanical damage to the capacitor or terminals:
