X7R formulations are called “temperature stable” ceramics and fall into EIA Class II materials, and COG (NPO) is the most popular “temperature-compensating” EIA Class I ceramic materials

• Multilayer Ceramic Capacitors whose temperature variation is within ±15% from -55°C to +125°C
• The capacitance change is non-linear
• AVX high voltage chips have advantages of high value, low leakage and small size, thus applications include as snubbers in high frequency power converters, resonators in SMPS and high voltage coupling/DC blocking
• These high voltage chip designs exhibit low ESRs at high frequencies
• Reduced noise X5R versions available
• Low profile versions available

Ceramic Capacitors exhibit low parasitics and excellent EMI filtering capabilities. In a multilayer configuration, they display high capacitance values and various voltage ratings over a wide temperature range. Multiple styles are available such as MLCC chips, leaded capacitors, stacked capacitors and capacitors that utilise unique geometries.

C0G (NP0) formulations show no aging characteristics

C0G (NP0) is the most popular formulation of the "temperature-compensating," EIA Class I ceramic materials. Modern C0G (NP0) formulations contain neodymium, samarium and other rare earth oxides. C0G (NP0) ceramics offer one of the most stable capacitor dielectrics available. Capacitance change with temperature is 0 ±30ppm/°C which is less than ±0.3% C from -55°C to +125°C. Capacitance drift or hysteresis for C0G (NP0) ceramics is negligible at less than ±0.05% versus up to ±2% for films. Typical capacitance change with life is less than ±0.1% for C0G (NP0), one-fifth that shown by most other dielectrics.
