Recommended LED forward current or recommended
input voltage
Design in accordance with the recommended operating conditions
for each product.
Since these conditions are affected by the operating environment,
ensure conformance with all relevant specifications.

Ripple in the input power supply
If ripple is present in the input power supply, observe the following:
1) For LED forward current at E
mentioned at "■Recommended LED forward current."
2) Please make sure the LED forward current for E
than 50 mA.
3) Please maintain the input voltage at least 4V for E
and Power voltage-sensitive type).
4) Please make sure the input voltage for E
(GU and RF voltage-sensitive type).
5) Please make sure the input voltage for E
(Power voltage-sensitive type).
Emin.
6) Please maintain the input voltage at least 3V for E
(for CC Type)
7) Please make sure the input voltage for E

Output spike voltages
1) If an inductive load generates spike voltages which exceed the
absolute maximum rating, the spike voltage shall be limited.

2) When Clamp diode or CR Snubber is used in the circuit, the spike
voltages from the load are limited. But the longer wire may
become the inductance and cause the spike voltage. Keep the
wire as short as possible.
