Military Glass-K Capacitors MIL-PRF-39014/21 CKR31, 32 APPLICATIONS CKR31BT These miniature multilayer ceramic capacitors, style CKR31 and CKR32, are qualified to Established Reliability specification MIL-PRF-39014/21. High volumetric efficiency and reliable performance result from the special GLASS-K dielectric, which is fused into a compact monolithic structure. These capacitors are available in three different stability characteristics. CKR31 CKR32BT CKR32 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-PRF-39014. At 200% of rated voltage, 125°C, at 4,000 hours, the capacitance change for each stability characteristic is as follows: BT: ±5% BU: ±10% BV: ±20% Insulation Resistance: At 25°C, 100,000 megohms or 1,000 megohm-microfarads. At 125°C, 10,000 megohms or 100 megohm-microfarads. Voltage/Temperature Rating: Rated voltage is 50 Vdc. The operating temperature range is -55°C to +125°C. Moisture Resistance: Meets or exceeds requirements of MIL-PRF-39014 and MIL-STD-202, Method 106. The capacitance change is less than 2% for stability characteristics T and U, and less than 5% for characteristic V. 31.75 (1.250) Min.
