A1 & A4 PTFE Trimmers

Voltronics / Knowles A1 and A4 Polytetrafluoroethylene (PTFE) Trimmers are capacitors featuring a high-reliability solid dielectric, positive tuning stops, and up to 5 (A4) or 13 (A1) full turns of linear tuning. Voltronics / Knowles A1 PTFE Trimmers are an ideal replacement for conventional miniature-air and sapphire dielectric trimmers. A1 assures no intermittent noiseless performance. A4 PTFE Trimmers offer the shortest length of any similar trimmer capacitor.
