Subminiature Microfuses
Subminiature microfuses are used on many Sun Printed Circuit
Boards. Subminiature microfuses are field replaceable.
PICO II Fuses
PICO II fuses are used on Printed Circuit Boards and Peripheral
devices such as Tape and Disk Drives. PICO II fuses are not field
replaceable because they are soldered in place.
PTCs
Positive Temperature Coefficient (PTC) thermistors are resistors
with a high positive temperature coefficient of resistance. The PTC
is used as a self-resetting fuse in overload applications. When an
overload current flows through a PTC, there is a specific time
period before the PTC heats up to its high-resistance state and
starts limiting the current. PTCs are not field replaceable because
