Kingbright Electronic Co. Ltd., Taiwan has advised that they will make a change to the encapsulation material used in their reflector SMD LEDs, using silicone only in place of the epoxy encapsulation currently utilised. This design improvement applies to the following Kingbright LED series:
In summary, with affect from 01.11.10 all Kingbright SMD series which start with KA or KAA will be produced with a silicone encapsulation.
Silicone encapsulated devises show at least one level of improvement in Moisture Sensitivity Level (MSL). Existing electrical and optical data will not be affected.
At the end of 2007 we advised you that Kingbright’s KA-3528 series had been replaced by the series KA-3528A as a result of a patent issue. The difference between these 2 series was only the shape of the connecting contacts.
We are pleased to advise that Kingbright are permitted to offer the KA-3528 series once again. Therefore we will change all part numbers starting with
KA-3528Axxx back to KA-3528XXX.
The benefit for all our customers is the lower price of KA-3528 series compared with those of the KA-3528A series.
