Trimmers Suited For 2-GHz Band

Measuring only 0.240" long x 0.090" in diameter, A2 series of 0.3 to 1.2 pF multi-turn precision trimming capacitors have 250 vdc working voltage and 500 vdc withstand voltage. Temperature coefficient is ±150 ppm/°C from -65°C to 125°C. Q is more than 1000 at 1 GHz, and self-resonant frequency is more than 5 GHz. The proprietary solid dielectric design provides high reliability because plates cannot short. Tuning is over four full turns with positive stops at minimum and maximum capacitance.
