Insulation Resistance: After a 2 minute charge at rated voltage or 500 V, whichever is less. At + 25°C: 400,000 Megohm for C ≤ .5µF. 200,000 Megohm - Microfarads for C > .5 Microfarads. At + 85°C: 20,000 Megohm for C ≤ .5 Microfarads. 10,000 Megohm - Microfarads for C > .5 Microfarads. At + 105°C: 2000 Megohm for C ≤ .5µF. 1000 Megohm - Microfarads for C > .5 Microfarads. Capacitance, Tolerance and Dissipation Factor: Capacitors shall be measured at a frequency of 1000Hz at + 25°C or else be referred to measurements made at that frequency and temperature. The maximum dissipation factor shall be 0.1%. Dielectric Withstanding Voltage: Capacitors rated below 1000 volts shall withstand a DC potential of 250% of rated voltage applied between terminals for not more than 5 seconds. Capacitors rated 1000 volts and above shall withstand a DC potential of 200% of rated voltage applied between the terminals for not more than 5 seconds. The test voltage must be applied and discharged through a resistor of one ohm per volt. Not more than one failure allowed in 12 units tested. Rated DC Voltage 200 400, 600 800, 1200, 1600 Maximum 60Hz Voltage 155 200 500 Polypropylene plastic film is employed as the dielectric in Type 715P ORANGE DROP® capacitors. Type 715P capacitors are ideal for applications where high AC current flow is found, as in certain solid-state TV vertical circuits, r-f generators and pulse-forming networks where dielectric heating is often a problem. The polypropylene dielectric film is similar to polystyrene in that it can handle high AC currents due to its low loss but with the added advantage of an operating temperature to + 105°C. Capacitance change with temperature is less than 3% over the entire operating temperature range. The temperature coefficient is negative and virtually linear at 180PPM/°C over the temperature range of + 25°C to + 105°C. This characteristic means the Type 715P is suitable for matching with positive TC resistors and inductors to maintain circuit stability. Type 715P ORANGE DROP® capacitors are conformally coated with a flame retardant epoxy. Performance characteristics, as well as curves showing typical variation in electrical characteristics as a function of temperature and frequency, are given. Humidity Test: Condition capacitors with no voltage applied for 72 hours at 95% relative humidity and + 75°C. Remove capacitors from humidity chamber, wipe surface dry of moisture and dry in circulating air for 4 hours. Measure insulation resistance after a two minute charge at + 25°C and rated voltage or 500 VDC, whichever is less. Minimum product of insulation resistance and capacitance shall be 50,000 Megohm-microfarads after test but need not exceed 100,000 Megohm. Not more than one failure in 12 units tested shall be permitted. DC Life Test: Capacitors are capable of withstanding a 500 hour life test at + 85°C at 150% of rated working voltage. After test, capacitance shall not have changed by more than 5% of initial value, insulation resistance shall not have decreased by more than 50% of the initial limit and dissipation factor shall not have increased to more than 0.1%. AC Life Test: Capacitors shall withstand the maximum 60Hz voltage for a period of 500 hours at + 85°C. |
