OneWhite Surface Mount PLCC-2 LED Indicator

Data Sheet

CAUTION: LEDs are ESD sensitive. Please observe appropriate precautions during handling and processing.

Description

This family of SMT LEDs is packaged in the industry

standard PLCC-2 package. These SMT LEDs have high

reliability performance and are designed to work under

a wide range of environmental conditions. This high

reliability feature makes them ideally suited to be used as

interior signs application conditions.

To facilitate easy pick & place assembly, the LEDs are

packed in EIA-compliant tape and reel. Every reel will be

shipped in single intensity and color bin.

These LEDs are compatible with reow soldering process.

The wide viewing angle at 120° makes these LEDs ideally

suited for panel, push button, oce equipment, industrial

equipment, and home appliances. The at top emitting

surface makes it easy for these LEDs to mate with light

pipes. With the built-in reector pushing up the intensity

of the light output, these LEDs are also suitable to be used

as LED pixels in interior electronic signs.

PRECAUTIONARY NOTES 1. Handling precautions 2. Handling of moisture sensitive device The encapsulation material of the LED is made of silicone for better product reliability. Compared to epoxy encapsulant that is hard and brittle, silicone is softer and flexible. Special handling precautions need to be observed during assembly of silicone encapsulated LED products. Failure to comply might lead to damage and premature failure of the LED.

3. Application precautions a. Drive current of the LED must not exceed the maximum allowable limit across temperature as stated in the datasheet. Constant current driving is recommended to ensure consistent performance. b. LED is not intended for reverse bias. Do use other appropriate components for such purpose. When driving the LED in matrix form, it is crucial to ensure that the reverse bias voltage is not exceeding the allowable limit of the LED. c.
