DESCRIPTION
The EN2, EP2, EPI and MR301 series power relays can meet the requirements of high quality and reliability in automotive
eIectronics applications.
The EN2 and EP2 series are the twin relays which have two units in one package and smaller than conventional two relays.
These relays are divided into two types for different usage. One is H bridge type and the other is separate type.
The EN2 series is suitable for heavy load applications (35 A max.). The EP2 series is designed for medium load applications
(25 A max.). The EP1 and MR301 series are the 1C contact form relays.
Many of these relays have been used in automotive electronics applications throughout the world.
