PICO , Very Fast-Acting Fuse (High-Reliability)
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 enduse 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.
