This document is a product information of high voltage ceramic disc capacitors (low loss type). It provides product models, rated voltage, rated capacitance, rated temperature, product characteristics, application scenarios and other information.
This handbook covers Panasonic's high‑voltage ceramic disc capacitor families – series KGE (1 kVDC to 6 kVDC), KBP (1 kVDC to 3 kVDC) and KRP (1 kVDC to 3 kVDC). It provides part‑number explanations, electrical ratings, mechanical dimensions, and recommended applications for each series.
Key features include a wide operating temperature range, low loss characteristics, flame‑retardant coating, and various lead styles. Detailed tables list capacitance values, tolerances, voltage ratings, insulation resistance, and dissipation factors, along with typical uses such as snubber circuits, inverter lighting, and LCD backlight ballast circuits.
| Operating Temperature Range | -25 °C to 105 °C (or -25 °C to 125 °C) |
|---|---|
| Rated Voltage (KGE series) | 1 kVDC to 6 kVDC |
| Rated Voltage (KBP/KRP series) | 1 kVDC to 3 kVDC |
| Capacitance Tolerance | +20 % at 1 MHz |
| Insulation Resistance | ≥10 000 MΩ |
| Dissipation Factor (≥30 pF) | Q > 1000 at 1 kHz + 20 % |
The KGE series can operate from –25 °C up to 105 °C (or up to 125 °C for some grades).
Typical applications include snubber circuits for switching power supplies, horizontal resonance circuitry for TVs and CRT displays, inverter‑type lighting apparatus, and ballast circuits for LCD backlighting inverters.
The KBP series is rated for 1 kVDC to 3 kVDC.
The minimum insulation resistance is 10 000 MΩ.
