265/266/267 Series,
PICO , Very Fast-Acting Fuse (High-Reliability)
®
QPL
Description
The 265/266/267 Series are high–reliability PICO
®
Fuses,
that are very fast-acting, with an insulating sleeve.
These fuses provide supplemental protection in end-
use equipment to provide protection for components
or internal circuits. They are not suitable for branch or
feeder circuit use. The Military version of the 265 Series
(except 1/16 ampere rating) is available in FM08A on
QPL for MIL-PRF-23419/8. To order, change 265 to 267
.
