10 / 12 page 10 s 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. 100 ms min.
