Description
The R1S/E series is an unregulated DC/DC converter in fully encapsulated open Frame
package style. This series has been designed to offer exceptionally high efficiency at low loads
and an extended operating temperature range. Uses include battery powered supplies, green
energy applications and general isolating/converting DC power where board space and high
efficiency is a premium.

** without marking denotes 5 pins out of 8 fitted (includes /H option) - e.g. R1S-3.305/EH
** with marking “8“ denotes 8 pins out of 8 fitted (/H option not available) - e.g. R1S8-3.305/E
* add Suffix “/H“ for 2kVDC Isolation Voltage - e.g. R1S-3.305/EH
* add Suffix “/P“ for Continuous Short Protection - e.g. R1S-3.305/EHP, R1S8-3.305/EP
* add Suffix “-R“ for tape & reel packing - e.g. R1S-3.305/EHP-R, R1S8-3.305/E-R
