Click on Emitter Link for emitter data sheet. Description The LZ4-4xxx10 Serially Connected MCPCB option provides a convenient method to mount LedEngins 10W emitters. The MCPCB connects all four (4) LED die in series and provides 2 Anode and 3 Cathode contact pads. The six recessed features allow the use of M3 or 4 screws to attach the MCPCB to a heat sink. The MCPCB also contains a Zener diode for enhanced ESD protection.

Slots in MCPCB are for M3 or 4 mounting screws. 3. LedEngin recommends plastic washers to electrically insulate screws from solder pads and electrical traces. 4. Electrical connection pads on MCPCB are labeled + for Anode and - for Cathode. 5. LedEngin recommends using thermally conductive tape or adhesives when attaching MCPCB to a heat sink. 2 LedEngin, Inc. LZ4-4xxx10 (R.0a - 05/12/08)
