GENERAL PURPOSE PTC THERMISTORS OVERCURRENT PROTECTORS
GENERAL PURPOSE
PTC CURRENT LIMITERS
Designed as resettable current
limiters, PTC thermistors offer an
alternative to conventional over-
current protection devices such as
fuses or circuit breakers.
A wide variety of sizes and current
ranges are available for many
electronic, industrial and automotive
applications. Both standard parts and
custom designs are offered.

APPLICATION CONSIDERATIONS:
PTC current limiters are intended for service on
telecom systems, automobiles, or the secondary of
control transformers or in similar applications where
energy available is limited by source impedance. They are
not intended for application on AC line voltages where
source energy may be high and source impedance low.
Fuses and circuit breakers result in total circuit
isolation after tripping. PTC thermistors provide a
current limiting function by switching to a high
resistance mode. Safety consideration must be given
to the potential shock hazard caused by the steady
state leakage current and voltage potential remaining in
the circuit.
Wire leaded PTC current limiting thermistors are intended
for applications which expect a limited number of tripping
operations. Actual life is a function of operating parameters.
For high duty cycle applications, ceramic PTC pellets
mounted in spring contact mechanical housings are
preferred.
Wire size, wire type and coating material can be used to
precisely tailor required operating characteristics.
Options Include: Tape & Reel; Wire Forms; Lead
Spacings.
