SR60-050 PTCサーミスタ - 0.5A リセット可能ヒューズ

My bench supply kept tripping on a 12V lamp circuit until I swapped in this 0.5A PTC, and the 60V rating gives me plenty of headroom for other projects. It resets fast enough that I don’t even have to unplug anything, which saves a lot of fiddling.

Fitted these into a small motor circuit that kept blowing regular fuses, and the 0.5A hold rating handles the inrush without a hiccup. The 60V rating gives me peace of mind for higher-voltage setups. They reset fast, so no more stocking spare fuses.

Had a small transformer that kept tripping my regular fuse, so I swapped in this 0.5A PTC thermistor and it’s been running clean for weeks now without a single hiccup. The 60V rating gave me confidence it could handle the load, and the resettable feature saves me from buying replacements.
