APPLICATIONS
These miniature multilayer ceramic capacitors, style CKR31
and CKR32, are qualified to Established Reliability specification
MIL-C-39014/21. High volumetric efficiency and reliable perform-
ance result from the special GLASS-K dielectric, which is fused into
a compact monolithic structure. These capacitors are available in
three different stability characteristics.
PERFORMANCE CHARACTERISTICS
Tolerance: ±20% and ±10% in characteristics “U” and “V”,
and ±10% and ±5% in characteristic “T”.
Stability Characteristics: Available as follows:
BT-TC: +2, -10%; TVC: +2, -10%
BU-TC: +2, -15%; TVC: +2, -15%
BV-TC: +20, -45%; TVC: +20, -50%
Dissipation Factor:
BT: ≤1.0%
BU: ≤1.5%
BV: ≤3.0%
Life: Meets or exceeds requirements of MIL-C-39014. At
200% of rated voltage, 125°C, at 4,000 hours, the capaci-
tance change for each stability characteristic is as follows:
BT: ±5%
BU: ±10%
BV: ±20%
Insulation Resistances: At 25°C, 100,000 megohms or
1,000 megohm-microfarads. At 125°C, 10,000 megohms or
100 megohm-microfarads.
Voltage/Temperature Ratings0: Rated voltage is 50 Vdc.
The operating temperature range is -55°C to +125°C.
Moisture Resistance: Meets or exceeds requirements of
MIL-C-39014 and MIL-STD-202, Method 106. The capaci-
tance change is less than 2% for stability characteristics T
and U, and less than 5% for characteristic V.
