8. Cautions

parallel in an application, it is recommended that a current limiting resistor be incorporated in the drive circuit, in

series with each LED as shown in Circuit below.

LED

(A) Recommended circuit.

(B) The brightness of each LED might appear different due to the differences in the I-V characteristics of those

LEDs.

products. Stress or pressure may cause damage to the wires of the LED array.

and reliability are well enough if you use it under any of the following conditions

・Do not use sulfur-containing materials in commercial products including the materials such as seals and

adhesives that may contain sulfur.

・Do not put this product in a place with a lot of moisture (over 85% relative humidity), dew condensation, briny air,

and corrosive gas (Cl, H2S, NH3, SO2, NOX, etc.), exposure to a corrosive environment may affect silver plating.

ESD (Electrostatic Discharge)

Static Electricity or power surge will damage the LED. Suggestions to prevent ESD damage:

Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs.

All devices, equipment, and machinery must be properly grounded.

Work tables, storage racks, etc. should be properly grounded.

Use ion blower to neutralize the static charge which might have

built up on surface of the LED’s plastic lens

as a result of friction between LEDs during storage and handling.

ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward voltage,

or “no light up” at low currents.

To verify for ESD damage, check for “light up” and VF of the suspect LEDs at low currents.
