450CC1210LR-C Datasheet | Littelfuse

Description The Littelfuse Lo Rho SMD PTC for Charging Cables provides protection from heat generated due to faults within the connector such as USB-C, micro USB, and many others. As connectors get smaller, their pin-to-pin spacings are shrinking which increases the opportunity for debris such as dust, dirt, or water to collect causing a fault. These faults can generate heat which may damage charging cables, the devices they charge, or the people using them.
