Trimmer Variable Capacitor Pak 5pF to 120pF 14 Pcs 7 Values

Yes, they are designed for RF and high-frequency circuits where precise capacitance control is needed.

No, variable capacitors are non-polarized, meaning they can be connected in any direction.

You can use a capacitance meter or LCR meter to measure its adjustable range.

A JML06 is adjustable, while a fixed capacitor has a constant capacitance value.

Use low-temperature soldering and avoid excessive heat to prevent damage.

Use a high-value resistor (e.g., 1MΩ) to slowly discharge it, avoiding short circuits that may damage the component.

It may break down or fail permanently, potentially short-circuiting the circuit.

Common failure modes include capacitance drift, internal short circuits, or dielectric breakdown.

This product is sold as a complete pack, but individual types may be available separately upon bulk request.
