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.
