Frequently asked questions
Which tool should I use to adjust a trimmer capacitor?
Use a non-metallic (plastic or ceramic) screwdriver so your hand and the tool do not change the capacitance while you tune.
Is it suitable for mains or high-voltage circuits?
No. With a 100V rating and 220V withstanding voltage, it is intended for low-voltage RF and tuning circuits. Check the rating before using it in any higher-voltage design.
