Notes

Moisture Sensitivity

XLamp MC-E LEDs are shipped in sealed, moisture-barrier bags (MBB) designed for long shelf life. If XLamp MC-E

LEDs are exposed to moist environments after opening the MBB packaging but before soldering, damage to the LED

may occur during the soldering operation. The following derating table denes the maximum exposure time (in days)

for an XLamp MC-E LED in the listed humidity and temperature conditions. LEDs with exposure time longer than the

time specied below must be baked according to the baking conditions listed below.

Temperature

Maximum Percent Relative Humidity

30% 40% 50% 60% 70% 80% 90%

30ºC 9 5 4 3 1 1 1

25ºC 12 7 5 4 2 1 1

20ºC 17 9 7 6 2 2 1

Baking Conditions

It is not necessary to bake all XLamp MC-E LEDs. Only the LEDs that meet all of the following criteria must be baked:

1. LEDs that have been removed from the original MBB packaging

2. LEDs that have been exposed to a humid environment longer than listed in the Moisture Sensitivity section above

3. LEDs that have not been soldered

LEDs should be baked at 80ºC for 24 hours. LEDs may be baked on the original reels. Remove LEDs from MBB pack-

aging before baking. Do not bake parts at temperatures higher than 80ºC. This baking operation resets the exposure

time as dened in the Moisture Sensitivity section above.

Storage Conditions

XLamp MC-E LEDs that have been removed from original MBB packaging but not soldered yet should be stored in a

room or cabinet that will maintain an atmosphere of 25 ± 5ºC and no greater than 10% RH (relative humidity). For

LEDs stored in these conditions, storage time does not add to exposure time as dened in the Moisture Sensitivity

section above.

RoHS Compliance

The levels of environmentally sensitive, persistent biologically toxic (PBT), persistent organic pollutants (POP), or

otherwise restricted materials in this product are below the maximum concentration values (also referred to as the

threshold limits) permitted for such substances, or are used in an exempted application, in accordance with EU Direc-

tive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment

(RoHS), as amended through April 21, 2006.

Vision Advisory Claim

Users should be cautioned not to stare at the light of this LED product. The bright light can damage the eye.
