Bi-Colour LED, 5 mm
Cautions
1. Over-current-proof
Customer must apply resistors for protection, otherwise slight voltage shift will cause big current change (Burn out will
happen).
2. Storage
2.1 The LEDs should be stored at 30°C or less and 70%RH or less after being shipped from RND and the
storage life limits are 3 months. If the LEDs are stored for 3 months or more, they can be stored for a year in a sealed
container with a nitrogen atmosphere and moisture absorbent material.
2.2 Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where
condensation can occur.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LEDs if necessary.
4. Lead Forming & Assembly
During lead forming, the leads should be bent at a point at least 1.6mm from the base of LED lens. Do not use the base of
the lead frame 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.
5. Soldering
When soldering, for Lamp without stopper type and must be leave a minimum of 3mm clearance from the base of the lens
to the soldering point. Do not apply any external stress to the lead frame during soldering while the LED is at high
temperature.
Recommended soldering conditions:
Note: Excessive soldering temperature and / or time might result in deformation of the LED lens or catastrophic failure of the LED.
6. 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.
