I am rebuilding a Tektronix TDS3BAT NiCd battery pack. This component was in series with the string of ten D cell NiCd batteries. I believe it is a PTC resealable fuse. It measure 0.08 Ohms with Kelvin test clips. Is it a PTC? What brand is it? Where can I find a spec sheet? Thank You, Chris |

The date code on the chips on the circuit board in the TDS3Bat are from 2001. |

Yes, most likely. This is quite similar: https://www.digikey.com/en/products/detail/littelfuse-inc/RGEF700-2/5029786 Possibly the G700 series is discontinued? May be able to find a datasheet on an archive site. Brand is née Raychem. 7A is a reasonable rating for D cells, and ten in series needs at least a 12V rating. FYI, your images don't show in Chrome, at least on my current configuration. https://blog.chromium.org/2019/10/no-more-mixed-messages-about-https.html Suggest enabling HTTPS or migrating to a server which supports it.
