Voltronics / Knowles TM & QM Glass Quartz Trimmers

Voltronics / Knowles TM & QM Glass Quartz Trimmers are the panel mount version of the dielectric trimmers. These trimmers are available up to 180pF of maximum capacitance and offer 178pF of tunable range. The TM and QM trimmers feature linear tuning with no reversals and offer high Q’s, low RF losses, low constant inductance, and high self-resonant frequencies. The dielectrics are available in the MIL Std version and feature PC38, PC39, and PC48 designations.
