Related Information

Applied for:

The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment,

communication equipment and household applications). Consult Betlux's Sales in advance for information on

applications in which exceptional reliability is required, particularly when the failure or malfunction of the LEDs

may directly jeopardize life or health (such as in aviation, transportation, traffic control equipment, medical

and life support systems and safety devices).

CAUTIONS for Through-Hole LED Lamps

1. Application
The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment, communication equipment and household applications). Consult Betlux's Sales in advance for information on applications in which exceptional reliability is required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation, traffic control equipment, medical and life support systems and safety devices).

2. Storage
The storage ambient for the LEDs should not exceed 30℃ temperature or 70% relative humidity. It is
recommended that LEDs out of their original packaging are used within three months
For extended storage out of their original packaging, it is recommended that the LEDs be stored in a sealed
container with appropriate desiccant or in a desiccator with nitrogen ambient.

3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary

4. Lead Forming & Assembly
During lead forming, the leads should be bent at a point at least 3mm from the base of LED lens. Do not use
the base of the leadframe as a fulcrum during forming.
Lead forming must be done before soldering, at normal temperature.
During assembly on PCB, use minimum clinch force possible to avoid excessive mechanical stress.

Soldering

When soldering, leave a minimum of 2mm clearance from the base of the base of the lens to the soldering point. Dipping the lens into the solder must be avoided.

Do not apply any external stress to the lead frame during soldering while the LED is at high temperature.

Recommended soldering conditions:

Wave Soldering		Soldering Iron
Pre-Heat	100°C Max.	Temperature	300°C Max.
Pre-Heat Time	60sec Max.
SolderWave	260°C Max.	Soldering Time	3sec Max.(one time only)
Soldering Time	5sec Max.

Note: Excessive soldering temperature and/or time might result in deformation of the LED lens or failure of the LED

ESD (Electrostatic Discharge)

Static Electricity or power surge will damage the LED.

Suggestions to prevent ESD damage:

 Use 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 “light off” at low currents. To verify for ESD damage, check for “light on” and Vf

of the suspect LEDs at low currents.

The Vf of “good” LEDs should be>2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP product

Drive Method

An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected in

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 A below.
