Knowles Capacitors AH Series High Q Porcelain Capacitors are designed for high-frequency applications requiring stability and reliability. These capacitors use a P90 dielectric material with a positive temperature coefficient and provides consistent performance across a wide temperature range. The low ESR and high Q characteristics make these devices ideal for high-power RF circuits. These porcelain capacitors offer a capacitance range from 0.1pF to 5100pF, with an operating temperature range from -55°C to +125°C. The AH Series capacitors have a dielectric withstanding voltage of 250% of their rated voltage and maintain insulation resistance of 10⁶MΩ at +25°C. These high voltage components are suitable for applications such as impedance matching, power handling, DC blocking, bypass, coupling, and RF power amplification.
