10-pack of Thomson MT-series .022µF 400V axial metallized polyester film capacitors for vintage electronics repair, tube radio service, audio restoration, amplifier work, ham radio restoration, CB radio repair, crossover work, and general bench replacement where 0.022µF 400V non-polarized capacitors are required.

These yellow axial Thomson MT capacitors are quality vintage film capacitors suitable for coupling, bypass, tone, signal-path, and restoration applications. A random sample from this lot tested at 18.54nF against the 22nF nominal value, which is within the ±20% tolerance range indicated by the M marking.

Historical Note:
Thomson was a known electronics manufacturer whose components appeared in service, industrial, audio, and communications applications. Axial metallized polyester capacitors like these were common quality bench-era replacement parts before many modern radial styles became standard. Their axial lead format makes them useful for vintage point-to-point wiring, older circuit boards, tube gear, radios, and restoration work where original-style installation matters.
