MCPCB-XR-MR11TR-RD

MCPCB-XR-MR11TR-RD: This 32 mm Round MCPCB is an exclusive design and is manufactured by Cutter Electronics. This printed circuit board with Aluminium base has been developed for Cree XRE and allows you to quickly create your prototypes of LED modules based on Cree XRE LED. With it’s high thermal conductivity of 2 W/mK , this printed circuit board is able to drain the heat of the LED components through the Aluminium base, which is ideal for LED lighting. This Metal Core PCB is manufactured with UL certified Aluminium substrates.

The MCPCB-XR-MR11TR-RD is designed to take 3 Cree XRE Leds

The design of the board was intended for connectivity through the centre base and is manufactured with Isolated via’s to avoid bare wire grounds on the board

Thermal Path :  Has a dielectric under the thermal pad of LED

The module requires careful attention to mounting and cooling to ensure that the junction temperature of the LED is kept well below the maximum rating as specified in the LED documentation published by Led Manufacturers

For optimal cooling, we recommend that the module be mounted to a suitable finned heat sink (aluminium or copper) that is exposed to open air. The module can be mounted to a heat sink in various ways

• 32mm pressure sensitive, thermally conductive tape (Recommended)
• Arctic Alumina thermally conductive adhesive
• Thermal Compound: Requires the use of mechanical fasteners

Before fastening the module to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximise heat transfer to the the sink.

The bottom of the LED MCPCB is electrically neutral, so it is not necessary to electrically isolate the base from the cooling surface.

Please note the use of Thermal Adhesives makes the PCB unlikely to be removed for servicing. Please consider this if removal of the board is desired as another TIM may be a better choice. 

Optics Support: The board is drilled to take The Ledil Cute series of narrow, medium and wide optics in the 35mm Quad format*

Termination: The board has two centre pads in Cathode and anode and uses isolated vias to avoid wire grounding

* some holders may require modifications to allow wire access to the PCB, Cutter assumes no responsibility for holder modifications
