PRG21BC6R8MM1RA Description

Short technical summary and product information.

This PTC resettable fuse from Murata provides overcurrent protection in compact surface mount designs. It features a hold current of 120mA, a maximum voltage rating of 30V, and an initial resistance of 6.8Ω. The ceramic construction ensures stable performance across the operating temperature range of -20°C to 85°C.

 

Housed in the industry-standard 0805 (2012 Metric) package, the device measures 2.00mm x 1.25mm with a thickness of 1.10mm, making it suitable for space-constrained applications. The surface mount design supports automated assembly processes.

 

Typical applications include overcurrent protection in low-power DC circuits, battery management systems, and consumer electronics. The PTC element automatically resets after the fault condition is removed, eliminating the need for fuse replacement.
