Axial Lead & Cartridge Fuses
PICO® > Very Fast Acting > 265/266/267 Series
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.
