POSISTOR r for Circuit Protection
Overcurrent Protection 56/80V Series
D max.
"POSISTOR" is a circuit protector whose resistance
value in normal operation is very low and in abnormal
situations like overcurrent or overheating, will be
increased to restrain overcurrent. "POSISTOR" can be
used for overcurrent protection against current
fuse or temperature fuse, due to its ability to return
to its initial condition when overcurrent is removed.
F±1.5
c Features
1. Best suited to meet the requirements for power
supplies and motor protection. Error-free
operations are assured by rush current.

2. Circuit is protected until current is turned off.
3. Restores the original low resistance value
automatically once the overload is removed.
4. Non-contact design leads to long life and no noise.
c Applications
1. DC cooling fan motors in of?ce equipment, e.g.,
computers, facsimiles, ?oppy disk drives and power
units.
7
Durable and strong against mechanical vibration
and shock because it is a solid element.
2. DC drive motors in VTRs and cassette tape recorders.
