Poke-home Connector MCPCB with thermistor for LZP emitter family LZP-H0xxT1 4x6 configuration Key Features Poke-home connectors already mounted on the MCPCB for easy connections 1-channel configuration allows for easy driver control for LZP emitters Very low Thermal Resistance for MCPCB adds only 0.1C/W Zener Diodes for ESD protection On-board thermistor for common constant current source with thermal feedback option LuxiGen LZP Lens family (15 / 23 / 32) holders align with the MCPCB cutouts Optional center die control for custom emitters Description The LZP-HxxxT1, MCPCB with three 2-pin poke-home connectors provides a convenient method to connect LED Engins LZP emitters. One 2 pin poke-home connector supports 4 parallel strings of 6 die in series a second one is for connecting to the thermistor, and a third one is available for an optional center die for custom emitters. Four recessed features allow the use of M3 or 4-40 screws to mount the MCPCB to a heat sink. There are additional mounting holes for the complementary TIR lenses and Zener diodes for enhanced ESD protection.

Maximum torque should not exceed 1N-m ( 8.9 lbf-in) LED Engin recommends plastic washers to electrically insulate screws from solder pads and electrical traces. LED Engin recommends using thermally conductive interface material when attaching the MCPCB to a heatsink Use solid or stranded wires with gauge size, 18, 20, 22 or 24AWG.
