MOSLED EXTREME ( mosX ) ceramic insulation 6XV (ANNA) 4040 hex MCPCB 34.0mm


Out of stock


These very 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, Samsung 351B/C/D, CREE XP-G3, XP-L2…

mosX PCBs are made from aluminum with chemically grown aluminum oxide ceramic (alumina) as insulation layer, which is excellent thermal conductor compared to even best classical MCPCB insulation layers (epoxy+ ceramic powder).

Advantages over copper DTP are:

  • electrically insulated – it’s possible to use LEDs and other components with electrically non-insulated thermal pad,like OSRAM Oslon (IR,white), while maintaining DTP – like performance
  • very flat surface – this is important for very small LED packages
  • lower mass – may be beneficial in headlamps
  • higher temperature insulator resistance – because there are no laminated epoxy based layers, ceramic insulator cannot be damaged due to excessive heat

6XV (ANNA) mosX MCPCBs are compatible with LEDIL ANNA-6-xx (or ANNA-7-xx) optics series, and they fit into Convoy C8 light (spacer is required).

With mosX MCPCBs and LD-B4 triple or quad LED builds are fast and easy, and more important – reliable because of real constant current driving/limiting.

Note 1: Black dot marks close to LED footprint represent LED cathode!

Note 2: MOSLED boards can be also used as normal MCPCBs without MOSFET, in that case MOSFET footprint should be shorted with metal/0 Ohm jumper.
