SRT Microcéramique Chip Capacitors with Negative TC

The NP0 (C0G) ceramic chip MLCC capacitor series with negative TC from SRT Microcéramique offers a wide range of options to suit any demand, including a selection of negative temperature coefficients (N150±60ppm, N220±60ppm, N330±60ppm, N470±60ppm, N750±120ppm, N1200±120ppm), as well as a capacitance between 0.47pF to 8.2nF across a range of chip sizes from 0603 to 1210, a wide selection of tolerances (±0.1pF, ±0.25pF, ±0.5pF, ±1%, ±2%, ±5%, ±10% and ±20%), voltages (50V or 100V) and a range of terminations. As with all SRT-MC components, the NP0 capacitors are popular in safety-critical industries thanks to their excellent quality and reliability, as well as zero ageing rate up to 10000 hours, zero voltage coefficient of capacitance and change of capacitance with frequency, and very low-temperature coefficient of capacitance. Their operating temperature is between -55°C and +125°C.

While this capacitor series offers a large number of options, customisation is possible on all SRT Microcéramique components – if none of the options are suitable for your application, please contact us to discuss the custom solutions available.

The dielectric strength test for the NP0 capacitors with negative TC is performed per method 103 or EIA 198-2-E with 250% of the rated voltage applied.

Typical applications for the SRT-MC NP0 series of ceramic capacitors with negative TC include:
