Precautions For Use

EHP-B03LS/UT04-P05/TR

1. Over-current-proof

Though EHP-B03 has conducted ESD protection mechanism, customer must not use the device in

reverse and should apply resistors for extra protection. Otherwise slight voltage shift may cause

enormous current change and burn out failure would happen.

2. Storage

i. Do not open moisture proof bag before the products are ready to use.

ii. Before opening the package, the LEDs should be kept at 30℃ or less and 90%RH or less.

iii. The LEDs should be used within a year.

iv. After opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less.

v. The LEDs should be used within 168 hours (7 days) after opening the package.

vi. If the moisture absorbent material (silicone gel) has faded away or the LEDs have exceeded the

storage time, baking treatment should be performed using the following conditions.

vii. Pre-curing treatment : 60±5℃ for 24 hours.

3. Thermal Management

i. For maintaining the high flux output and achieving reliability, EHP-A08 series LED package should

be mounted on a metal core printed circuit board (MCPCB) with proper thermal connection to

dissipate approximately 1W of thermal energy under 350mA operation.

ii. Special thermal designs are also recommended to take in outer heat sink design, such as FR4

PCB on Aluminum with thermal vias or FPC on Aluminum with thermal conductive adhesive, etc.

iii. Sufficient thermal management must be conducted, or the die junction temperature will be over

the limit under large electronic driving and LED lifetime will decrease critically.
