Resettable PPTC fuses

20 January 2010 Circuit & System Protection

Bel Fuse has expanded its 0ZCx Series of surface mountable polymeric positive temperature coefficient (PPTC) resettable fuses. The RoHS-compliant, lead-free and halogen-free series features Bel’s unique polymer formulation to ensure long-life performance and over-current protection in a broad range of consumer electronics.

Offered in five EIA/IECQ case sizes ranging from 0805 to 2920, the chip fuses are rated up to 60 V d.c. with current ratings up to 3 A. Chips are specifically engineered to limit the flow of dangerously high current during fault conditions to protect products and systems from over-current surges and over-temperature faults. In the event of a fault, fuses reset themselves once power is removed, the fault is corrected and the voltage is re-applied.

Boasting a fast trip time and provided in an industry-standard 0805, 1206, 1210, 1812 or 2920 footprint, the fuses feature hold current ratings from 50 mA to 3 A, over an operating temperature range of -40°C to +85°C.
