* add suffix "/H4" for 4kVDC isolation and "/H6"
for 6kVDC isolation
add suffix "/A

"B
B" Pinning is NOT available for this series !
add suffix "/M
M" for metal case
e.g. REC3-2412SRW/H4/AM =
4kVDC isol. / Pinout "A
A" / metal case
This series offers high isolation of 4kVDC (= option "H4") or 6kVDC (= option "H6") making it ideal for medi-
cal applications and other sophisticated industrial applications. UL-1950 approval of this series is is applied
for. Packaging can be either DIP-24 non-conductive plastic or 5-side-shielded DIP24 metal case (= option "M")
as well as DIP24-SMD case (= option "SMD"). For all the above variants, 2 industry-standard-pinouts
(= option "A" or "C") are available.
Description
Notes :
1. If the options "/M
M" for metal case and
"/S
SM
MD
D" for SMD pinout are combined the
maximum allowed isolation voltage is 2kVDC
because of the shoter distances between
pins and metal-case, so only available SMD-
option in metal-case is "/H
H2
2".
DIP-24 through-hole case and SMD-plastic
case are not affected and offer the desired
isolation barriers of 4kVDC for "/H4" option
and 6kVDC for "/H6".
