The SR-02-H2060 has been specifically designed to accommodate the Polymer and Khatod 7 Cell Cluster series of optics, including:
The LEDs can be powered singly or in series with the addition of 0 ohm resistors or solder dots. A Vishay NTC 10K Thermistor (NTHS0805N02N1002J) is mounted to the board to monitor temperature and can be used for foldback temperature control. For more information about using the thermistor, please review our SR-02 Thermal Measurement Guidelines document.
Want to power this LED assembly from a voltage as low as 10VDC? Then check out the FlexBlock LED driver. A single driver can power all 7 of these LEDs connected in series with any voltage from 10V to 18V*.
Need a mixture of different color LEDs pre-mounted to this board? A custom version of this assembly is also available.
* The maximum input voltage to the driver must be less than the total forward voltage of all series connected LEDs.

- Values based on 350mA and a Thermal Pad temperature of 25°C.
- Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
- This is the maximum operating current that we recommend for this LED. Higher drive currents may be possible, but will require careful design of a suitable cooling system.
- At 350mA.
- Typical thermal resistance from the LED Junction to the bottom of the FR4 board.
- This is the value we recommend you use for determining driver input voltage.
* Results will vary depending on the quality of the dielectric material used in the MCPCB base.

SR-02-H2060 LED assemblies must be operated to ensure that the junction temperature of the LEDs are kept well below the maximum ratings as specified in the LXM2-PH01-0060 datasheet. A heat sink must always be used when operating this assembly. The size of the heat sink will depend on the ambient temperature and the current that is used to power the LEDs. Bench testing that we have conducted with a SR-02-WN300 assembly powered at 700mA in an open air environment and an ambient temperature of 25°C has indicated that a heat sink with a thermal rating of 3.5 C°/W or lower should be adequate. However, you will need to perform your own testing and analysis to determine if this size of heat sink will be suitable for your application.
The SR-02-H2060 must be fastened to the heat sink using a thermal interface material such as our pre-cut Bond-Ply 100 pressure sensitive, double sided thermal tape or Arctic Silver thermal adhesive. If you are using thermal tape, we recommend that the assembly also be fastened to the heat sink using three 4-40 screws. Before fastening the assembly to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximize heat transfer to the the sink. Be careful not to warp or distort the PC Board by over tightening the screws.
