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.

■ NOTICE
(1) Capacitive load
If the load is capacitive, an inrush current to charge the load with poses a problem. In this case, a current-limiting
resistor or surge suppressor coil is connected in series to the contacts to suppress the peak current.
(2) Clinching terminals
To secure the relay temporarily to a printed circuit board for soldering, particular terminals are allowed to be clinched
within a particular angle. other terminals, never clinched.
The terminal numbers and the angle for clinching of each series are as follows.
1) No.4 and no.5 terminals to 45° maximum for H bridge type of EN2 and EP2
2) No.5 and no.9 terminals to 45° maximum for separate type of EN2 and EP2
3) No.4 and no.5 terminals to 45° maximum for EP1
4) No.1, 4 and no.5 terminals to 45° maximum for MR301
(3) Drive circuit
Since the coil of a relay has an inductive impedance, a counter electromotive force is generated when the circuit
is opened. This voltage may damage the relay driver IC. Therefore, a diode is connected in parallel with the coil,
as shown in figure 1.
