Mike's Electronic Parts has been in the family since 2003. It is time for me to pass the business on to my sister. Mike's Electronic Parts will no longer accept orders after 6/19/2026. It will take us around 4 weeks to get everything moved to the new location and setup for business. The store is being renamed Atomic 29 and will be available at https://www.atomic-29.com when it is ready to go. Thank you for your patience during the move.

Plastic Variable Capacitor Dual Section 266pf

Plastic Variable Capacitor Dual Section 266pf

Price: $6.39 Each

Part Number: VarCap266

Description

These are small plastic variable capacitors with a dual section 0-266pf these can be connected to give a total capacitance of 0-532pf.

Screws and washers for the variable capacitor are available in two lengths: 5/32" (4mm) and 3/16" (5mm). The shaft and two mounting holes are both tapped metric M2.5.

For AM Radio match the dual section 266pf variable capacitor with the 180uh Loopstick Antenna Coil. Use both sections of the 266pf variable capacitor for a total of 532pf. You can optionally include one or more of the trimmers to lower the frequency range slightly if needed.
