Features / Benefits
• RoHS 6 compliant
• Low DCR
• Both high and low hold current designs
• High voltage ratings
• Unique polymer formulation for superior functional life performance
Bel’s polymer PTC (positive temperature coefficient) devices offer superior
functional life performance due to a unique polymer formulation. Like our
extensive line of traditional fuse products, our resettable fuses protect against
harmful overcurrent surges and overtemperature faults by limiting the flow
of dangerously high current during fault conditions. However, our new PTC
devices will reset after power to the circuit is removed, the fault is cleared,
and power is reapplied to the circuit. This reset-ability protects electronic
equipment, which remains fully functional, and eliminates the need for service
personnel to physically replace a fuse.
Our PTC devices can be confidently designed into industrial, computer,
battery, consumer electronics, telecom and automotive applications where
they help protect valuable electronic systems and reduce warranty and
services costs. Effective in a wide range of circuit protection applications,
Bel's resettbale fuses are Component Recognized by UL (E305051)
and are RoHS 6 compliant.
