Dielectric Laboratories has announced a number of specification extensions to its ultra-low ESR and high-Q MLC capacitors. In both cases, temperature performance has been extended to 175°C to give engineers more scope in their designs.
These new improved TCC (temperature coefficient of capacitance) figures apply to the company’s UL ceramic dielectric capacitors in case size C07 (0711) and AH porcelain dielectric capacitors in case size C17 (1111) – both with SMD compatibility. Applications include impedance matching, power handling, DC blocking, bypass, coupling, tuning and feedback in circuit designs covering oscillators, timing, filters, RF power amplifiers and delay lines.
UL is an EIA Class I Stable TC, NP0, ceramic dielectric, with ultra-low ESR, high Q and low noise. The parts can be operated up to +175°C with TCC of 0 ±60 ppm/°C (limited to +125°C at 0 ±30 ppm/°C). They find use in any application where heat generation or signal loss are concerns. They are considered high-voltage in case size C07 and can be operated at up to 500 V d.c. over the capacitance range of 0,3 pF to 47 pF, extending to 100 pF if derated to 200 V d.c.
The AH EIA Class I Positive TC, P90 porcelain dielectric now achieves the +175°C rating with a TCC of 0 ±20 ppm/°C. Applications are where high Q, coupled with low ESR, is a priority. They have a dielectric constant that increases with temperature (90 ppm/°C) giving established reliability, low noise and high self-resonance. Useful for temperature compensation where other board components may be losing capacitance with temperature, these parts have a capacitance range starting at 0,3 pF and extending to 1000 pF over the voltage range 50 V, to a high working voltage of 1 kV.
