Description

This is an Air Variable Capacitor. The 365pf Variable Capacitors were very common years ago. The manufacturer I use now makes a 384pf variable capacitor. Older versions from this manufacturer were rated 381pf. The extra 20pf of these from a 365 pf capacitors is small so they should work fine to replace any variable capacitor that calls for 365 pf .

The 384pf Variable Capacitor is very popular with Crystal Radio Set ( Xtal Radio Set ) builders and is still popular with Ham Radio enthusiasts using them in all kinds of electrical circuits.

These 384pf Air Variable Capacitor are good quality ball bearing front shaft.

Minimum capacitance: ~15pf

    The venerable 365pf variable air capacitor is getting tough to find. Mike’s has filled a niche with his 384pf cap. Works great – smooth and static free. Note the mounting threads are a 4 40. Highly recommend this capacitor.

Hi, will this 384pf cap work well with .27 mH inductor in a crystal radio ?

Hi John, A .27mH (270 uH) inductor with the 384pf variable capacitor should cover from just below the AM band to a little over the AM band. We have an LC inductance calculator that will allow you to calculate the upper and lower range for a given inductor and capacitor. https://www.mikeselectronicparts.com/lc-inductance-calculator/

How does one mount these capacitors in a box in use?

Hello, there are 2 holes 6-32 on the front and 4 holes 4-40 on the bottom. Either of these can be used to secure the capacitor.
