- LED junction to bottom of module.
- For maximum life, the board temperature must be kept below this value.

CONFIGURATION & PERFORMANCE
Connecting wires can be hand soldered directly to the module or pressed into place using two optional low profile
ERNI 474340 IDC wire to board connectors.
These highly reliable connectors include an integrated, UV resistant cap that precisely holds and guides the wire while it is pressed into the contact creating a gas-tight, cold-welded connection. The connectors are designed for single use. Wires cannot be removed after they are pressed into place.
The connector can accommodate AWG 24/7 or 26/7 stranded wire with a maximum wire insulation diameter of 1.06 mm.
POWERING THE MODULE
UV LEDs are sensitive to drive current that exceeds the LED’s maximum ratings. A suitable LED driver must be used to power this LED module. Current limiting resistors must not be used.
To maximize LED life and minimize wavelength shifting, always use the lowest possible drive current. For example, if you require 4 mW of light output, it is better to use a 3-UP module powered at 10 mA rather than a 1-UP powered at 40 mA.
Even though XBT-1313-UV LEDs are low power, the designer still must ensure that the LED junction temperature is kept well below its maximum rating in order to prevent reduced LED life and peak wavelength shifting. The LED module should always be mounted to a suitable cooling surface. Pages 4 to 7 of the Pages 4 to 7 of the UV-02 datasheet provides mounting instructions and details on how to determine the approximate junction temperature of mounted LEDs.
The LED module can be fastened to a cooling surface in one of two ways:
Mechanical fasteners must not be used.
As many plastic and glass optics block UV-C light, secondary optics cannot be used with this module.
