The CREE XLamp MC-E is the possibly most innovative high power multichip emitter on the market. The 8pin layout allows to drive each of the 4 chips separatly with up to 700mA/chip. It also contains the advantages of the currently lowest thermal resistance of only 3¢XC/W and the highst lumen density per mm2.

Cree is one of the pioneers in the development and manufacture of extremely bright and reliable LEDs. The XLamps are up to 50% brighter than other products available in the market. The XLamp product family has integrated Cree High-Power LEDs with innovative SMD (Surface Mounted Device) packaging technology. The resulting product offers optimal conditions for light solutions on LED technology basis at an unrivalled competitive price.

What makes the XLamps MC-E special?

- Driveable up tp 700mA
- SMD technology
- Reflow solderable
- Finest selections
- Low operating voltages
- Integrated lense
- Small Dimensions
- ESD > 2000V

Successful usage of high power LEDs:

Heat management

Applications with high power LEDs need enduring, adequate and plane heat conduction from the first moment of use. It is very important and neccessary to get the heat off the devices to ensure the maximum light output, lifetime and efficiancy.

Drive management

LEDs should be run with a constant current in addition to the manufacturers recommendations. To ensure this we recommend to take constant current power supplies because resistors are always a risk factor in high power LED applications.

EMC protection

LEDs are sensitive against heat and electric charge. Please avoid any kind of short circuits or electric discharge to the illuminant. The chip can be damaged or even destroyed.

Storage / JEDEC level

The storage temperature should be from -30íu up to + 80íu in dry ambience. After opening a sealed bag the content should be mounted rapidly. Once absorbed humidity can be removed by tempering the LEDs in some cases. More information can be found in the manufacturers datasheets or on the manufacturer homepages.

Soldering conditions

Each LED has its own soldering conditions that the user should pay attention to. After the launched lead free processing specifications many standarts have changed. Information about recommended soldering can be found in the manufacturers datasheets or on the manufacturer homepages.
