*Note—Short lead length not available in tape-and-reel packaging.
Note—Hi-Rel solderability applications should specify solder-dipped leads by
adding -SD suffix to part number.
The radial lead package of the PC-Tron
®
is ideal for auto inser-
tion using standard industry equipment. The 0.2” lead spacing
aids ease of design. Standard wave soldering techniques will
not affect the electrical performance of this unique fuse. Due
to its molded construction, the device is unaffected by the
board washing process. These features greatly reduce the
product installation cost while increasing reliability.
The PC-Tron
®
is available in a wide variety of options offering
flexibility to the design engineer. Available in standard pack
(5-in), bulk (100-in), and tape and reel. In addition, the
PC-Tron
®
may be ordered with short (approximately 0.10”)
or long (0.75”) lead length. The tape and reel comes standard
at 0.75”.
The short lead length may be used with the optional socket.
The auto insertable socket allows field replacement of the
PC-Tron
®
subminiature fuse.
CE logo denotes compliance with European Union Low Voltage Directive

Short-Circuit Performance
The PC-Tron
®
subminiature fuse offers short-circuit perfor-
mance which until now could only be found in much larger
size glass tube fuses. At 250 VAC, the 1/2 to 3 amp PC-Tron
can safely interrupt 50 amperes; at 125 VAC the 1/2 to 5 amp
versions can interrupt 10,000 amperes. This high interrupting
capacity makes the PC-Tron subminiature fuse ideal for line-
side protection of power supplies.

The PC-Tron
®
subminiature fuse is UL recognized for DC sup-
plementary overcurrent protection to provide individual protec-
tion for components or internal circuits in equipment.
The test method detailed below was chosen to emulate DC
Bus application. Suitability for a specific application is depen-
dent on time constants and capacitance values. It is the
responsibility of the customer to evaluate the information pro-
vided for applicability to their particular application.
