Notes

TOSHIN KOGYO's TCP-Cap family includes PVW, PVWZ, PVG, PUW, PUWZ and PUG. Series names are printed in full even on small cases, making identification easier. In the date code, the left portion represents the year and the right portion the month. Sleeved and sleeveless versions occur within a series. The source reports that these high-polymer solid parts may not have been made in TOSHIN's own factory, instead suggesting OEM/ODM or an affiliated manufacturer.
