Multifuse^®Products

Bourns Multifuse family of Polymer Positive

Temperature Coefficient (PPTC) “resettable

fuses” are used in a wide variety of circuit

protection applications.

Applications

• Computer

• Battery

• Automotive

• Telecommunications

• Industrial

Under fault conditions the device resistance

will rise exponentially and remain in a

• Consumer

“tripped” state, providing continuous circuit

protection until the fault is removed. Once the

fault is removed and the power cycled the device

will return to its normal low resistance state.

What’s New in this Edition

• Telecom Rated Products

• MF-R/90

• MF-R/250

• MF-R/600

Features/Benefits
