Description
The 1N66xxUB Series of switching/signal diodes
feature ceramic bodied construction for military
grade products per MIL-PRF-19500/578/609. These
small, low capacitance diodes, with very fast
switching speeds, are featured in a surface mount
UB package with various polarities available.
These devices are ideally suited for high frequency
data lines, RS-232 & RS-422 interface networks,
and Ethernet 10 Base T, LAN & computers.
