MIL-PRF-49470 ELECTRICAL AND PERFORMANCE CHARACTERISTICS
(ALL CHARACTERISTICS AND TEST METHODS IAW MIL-PRF-49470)
ELECTRICAL CHARACTERISTICS
Rated Voltage: 50/100/200/500 volts.
Temperature Coefficient:
Capacitance: Measured at 1.0 volt (open circuit) and 1KHz.
See tables on pages 2 through 5.
Capacitance Tolerance: J = ±5%, K = ±10%, M = ±20%.
Dissipation Factor: When tested at 1.0 volt (open circuit)
and 1KHz, BP characteristic shall be .15% maximum and
BX/BR/BQ characteristic shall be 2.5% maximum.
Dielectric Withstanding Voltage: Dielectric withstanding
voltage will be tested at 250% of rated voltage except for
500V rated parts which will be tested at 150% of rated voltage.
Insulation Resistance:
At +25°C, rated voltage: 1011Ωor 1000 MΩ–µF,
whichever is less.
At +125°C, rated voltage: 1010Ωor 100 MΩ–µF,
whichever is less.
PERFORMANCE CHARACTERISTICS AND
TEST METHODS (M49470 PART NUMBERS)
Operating Temperature Range: The operating temperature
range is -55˚C to +125˚C.
Thermal Shock: All parts are cycled between -55˚C and
+125˚C, 5 times.
Voltage Conditioning: All parts are tested for 96 hours at
125˚C and 200% of rated voltage except 500V rated parts
are tested at 120% of rated voltage. The overall percent
defective allowed (PDA) is 10%.
Solderability: Meets Mil-STD-202 and J-STD-001 requirements.
Resistance to Soldering Heat: Parts withstand 260˚C for 10
seconds with no degradation in electrical performance or
lead attachment.
Terminal Strength: Leads will withstand 5 pounds (4 pounds
for case code 5) of applied force without rupturing.
Moisture Resistance: Every 3 months, parts are tested for
20 cycles at 90% RH and between -10˚C to +65˚C. Bias is
applied during the first 10 cycles.
Life: Parts are tested for 1000 hours at +125˚C and 200% of
rated voltage except 500V rated parts shall be tested at
120% of rated voltage.
Barometric Pressure: Parts will operate at rated voltage
(80% of rated voltage for 500 volt parts) at reduced pressure
up to 100,000 feet.
Shock, Specified Pulse: Parts remain operational during
and after impacts of 100 G’s.
Vibration: Parts remain operational during and after operating
in high vibration environments of up to 20 G’s.
Marking: Marking shall be in accordance with Mil-STD-1285
and Mil-PRF-49470. Minimum marking will be “JB”,
manufacturer’s code (PCI), capacitance and tolerance, and
date code. Full marking will be included on the package.
Cage Code 60212:
Presidio Components, Inc.
ADDITIONAL REQUIREMENTS
(T49470 PART NUMBERS)
Ultrasonic Imaging: All parts are imaged during in-process
testing to remove voids and delaminations IAW EIA 469.
Destructive Physical Analysis: A sample of chips is
examined prior to assembly for defects in the microstructure.
As part of Group A, an additional sample is examined for
cracks or assembly defects.
Thermal Shock: Prior to voltage conditioning, all parts are
cycled between -55˚C and +125˚C, 20 times. Prior to life
test sample pieces receive 100 cycles under conditions out-
lined above.
Voltage Conditioning: All parts are tested for 168 - 264
hours at 125˚C and 200% of rated voltage except 500V rated
parts are tested at 120% of rated voltage. The overall percent
defective allowed (PDA) is 5% for case codes 4 and 5 and 8%
for all other case codes. The PDA in the last 48 hours of volt-
age conditioning is .5% for case codes 4 and 5, and 1% for all
other case codes, or 1 piece whichever is greater.
Life: For qualification, parts are tested for 4000 hours at
+125˚C and 200% of rated voltage except 500V rated parts
shall be tested at 120% of rated voltage. For each lot, 12
pieces are tested for a 1000 hours under conditions out-
lined above.
Humidity, Steady State, Low Voltage: Six pieces are tested
from each lot at 1.3 volts, 85% RH and 85˚C, to ensure the
absence of low voltage failure mechanisms. These
mechanisms include microcracking.
Marking: Parts will be marked as M49470 parts except “JB” is
replaced with “JT”.
Dielectric Type Bias = 0 Volt Bias = Rated Voltage
BP All Voltages ±30PPM ±30PPM
BX 50/100V ±15% +15, -25%
BR 200V ±15% +15, -40%
BQ 500V ±15% +15, -50%
