Polypropylene Capacitors
Type 32PL
 
SPECIFICATIONS
DIELECTRIC WITHSTANDING
VOLTAGE
200% of rated voltage applied through a minimum
limiting resistance of 100 Ohms/Volt. Duration of
voltage stress shall be 15 seconds minimum and 1
minute maximum at 25°C.
FEATURES
Wrap and fill construction
Excellent long-term stability
Superior "Q" for tuned circuits
High insulation resistance
Linear temperature coefficient (-55°C to
+85°C)
Quality control procedures per Mil-Q-9858
INSULATION RESISTANCE
At 25°C after 2 minutes of electrification at rated
voltage or 500 VDC, whichever is less, the minimum
product of Insulation Resistance and Capacitance
shall be 250,000 megohms-microfarads, but need
not exceed 250,000 megohms.
Extended foil design
APPLICATIONS
Computers
Data Processing Equipment
DISSIPATION FACTOR
Shall not exceed .05% when measured at 25°C and
1000 Hz, ±20 Hz. See characteristic curves for D.F.

Navigation and Distance Measuring Equipment
Communications Equipment
CAPACITANCE AND TOLERANCE
Shall be measured within the tolerance limits
specified. Measurements will be made at 25°C and
1000 Hz, ±20 Hz.
Timing and Retrace Circuits
Integrating Networks
High "Q" Low Loss Filters
Peripheral Equipment
LIFE TEST
Shall withstand 140% of rated voltage at 105°C for
250 hours. One failure in twelve shall be permitted.
HUMIDITY RESISTANCE
Meets requirements of Mil-C-27287, Para. 3.12
when tested in accordance with Mil-STD.-202,
Method 103 B, Condition B.
TEMPERATURE COEFFICIENT
Capacitance shall change linearly over operating
temperature range range of -55°C to +85°C at rate
of -290, ±75 parts per million/°C.
LEAD PULL AND BEND TEST
Steady pull of 5 pounds applied axially to leads for
one minute. Bend test shall consist of one bend from
the point of egress, first 90° in one direction, back to
the original axial position, and then 90° in the
opposite direction with no evidence of breakage.
CAPACITANCE STABILITY (DRIFT)
Less than .2% when measured in the following
manner: three capacitance readings at 25°C, each
made prior to and after temperature cycling from
room to 105°C, and room to -55°C. The
mathematical difference between the two extremes,
divided by the intermediate value, and then multiplied
by 100, yields the stability expressed in percent.
TEMPERATURE RANGE
-55°C to +105°C with full rated voltage applied.
