Bourns® Multifuse® – Resettable Fuse Protection
Multifuse® Products – What They Are
Bourns® Multifuse® family of Polymer Positive
Temperature Coefficient (PPTC) Resettable
Fuses are used in a wide variety of circuit
protection applications. Under fault conditions
the device resistance will rise exponentially and
remain in a “tripped” state, providing
continuous circuit protection until the fault is
removed. Once the fault is removed, the power
cycled the device will return to its normal low
resistance state.

Bourns® Automotive Multifuse® Products
Multifuse® Products – Automotive
Applications
As the number of electronic safety, comfort
control, and power management systems
has increased, the need for integrated reliable
circuit protection solutions has evolved
into a critical design feature on all new
automotive platforms. Bourns, Inc. has
developed its line of Multifuse® Polymer PTC
Resettable Fuses to help automotive
manufacturers and designers meet this need.
Typical examples of the electronic
circuits where Bourns® Multifuse® products can
be seen are:
• Under the hood applications with new high
temperature polymer PTC resettable fuses
• Steering column control modules
• Alarm modules
• Instrument panel/cluster protection
• Power Bus (e.g. AS System) - node protection
• Climate control units
• DC motor protection
• Window lifts
Multifuse® Products – Features for Automotive
Applications
• Resettable overcurrent protection – offers
greater reliability, longer part life and
Multifuse® Polymer PTC Resettable Fuses can
be located close to the load being protected
instead of traditionally locating fuses in a fuse
box.
• ISO/TS 16949 Certified – September 2005 sees
the Bourns, Inc. production facility for the
Multifuse® Polymer PTC Resettable Fuses
certified to ISO/TS 16949. Together with ISO
9001:2000, ISO/TS 16949 specifies the quality
system requirements for the design,
development, production, installation and
servicing of automotive related products.
• AEC Certification - Bourns® Multifuse®
family of Polymer Positive Temperature
Coefficient (PPTC) Resettable Fuses can be
certified to AEC-Q200-Rev B. This
specification defines the stress test
requirements and reference test conditions
for qualification of passive electrical devices
in automotive applications as defined by a
committee of automotive companies.
• RoHS compliant – All Bourns® Multifuse®
Polymer Positive Temperature Coefficient
(PPTC) Resettable Fuses are RoHS
compliant as standard.
Multifuse® Products – What’s New in this
Edition?
• MF-RHT Series – High temperature radial
through-hole product series
• MF-SMHT Series – High temperature
surface mount product series
• MF-RG Series – 16 V radial through-hole
product series.
