Knowles Capacitors J Series Ceramic Chip Trimmer Capacitors

Knowles Capacitors J Series Ceramic Chip Trimmer Capacitors are more efficient and outperform all similar trimmers while providing stability over time with low capacitance drift. These capacitors offer up to 50% higher Qualify Factor (Q) than similar trimmers. The J series capacitors are usable over 1GHz and available in a wide range of capacitance values, from 0.5pF to 120pF. These ceramic chip trimmer capacitors find application in RFID, medical devices, cellular technologies, and tunable filter circuits.
