Description

Available until stock is exhausted

These high performance metal core PCBs except for LEDs, also have footprints for external power MOSFET  and NTC temperature sensor on single board, and they are compatible with LD-B4 driver. MOSFET on such MCPCB has best possible thermal contact with flashlight body, so it can dissipate a lot of power without overheating, which is very important when driving modern low Vf LEDs like Luxeon V, SST-40, Nichia 219C, CREE XP-G3, XP-L2 at currents up to 5A. MOSLED PCBs are made from aluminum with high performance insulation layer, and tests show they perform significantly better than copper NON-DTP boards, and they are close to DTP copper MCPCBs performance. At 3A per LED, difference in brightness compared to DTP copper PCB is only 2,3% (copper NON-DTP gives 3,8% lower output).

MOSLED MCPCBs are over 3 times lighter compared to copper DTP and NON-DTP boards, which makes them especially suitable for headlamps and EDC lights.

Note 1: Due to high thermal conductivity on whole board area, soldering wires is more challenging; one simple solution is to preheat PCB with hot air or with soldering iron (by holding iron tip on + or – pad) and then solder wires. During soldering, PCB must be thermally insulated(piece of thick paper is good enough) from any thermally conductive objects.

Note 2: White dot marks close to LED footprint represent LED anode!

Note 3: MOSLED boards can be also used as normal MCPCBs without MOSFET, in that case MOSFET footprint should be shorted with metal/0 Ohm jumper.
