1630480-3 – TYCO ELECTRONICS

The 1630480-3, manufactured by TE Connectivity (formerly TYCO), is a ceramic positive temperature coefficient (PTC) thermistor resettable fuse. The core component, identified as CB10LV103M, indicates a 10mm diameter chip size, LV series (likely indicating low voltage operation), and a nominal resistance of 10 kΩ (103 = 10 x 10^3). This device is designed to protect circuits from overcurrent conditions by exhibiting a sharp increase in resistance when its trip current is exceeded, effectively limiting the current flow. Upon removal of the fault condition and subsequent cooling, the thermistor automatically resets to its low-resistance state. The “14+” designation likely refers to a specific production lot or date code. RoHS compliance confirms adherence to Restriction of Hazardous Substances directives, limiting the use of specified hazardous materials in its construction. This component is suitable for applications requiring self-resetting overcurrent protection in low-voltage DC circuits.
