Integrated LED backlight for visibility in low-light conditions.
While the exact turn ratio depends on the specific circuit design the transformer was built for, the SN102 series is generally found in medium-power applications Kl Sn102 94v-0 Datasheet
The most critical distinction to make is regarding the suffix. This is not a part number. It is a flammability standard rating issued by Underwriters Laboratories (UL). It is a flammability standard rating issued by
| Parameter | Symbol | Value | Unit | | :--- | :--- | :--- | :--- | | Junction-to-Ambient (PCB mounted) | RθJA | 110 | °C/W | | Junction-to-Case (top) | RθJC | 25 | °C/W | | Junction-to-Case (bottom) | RθJB | 45 | °C/W | Operating beyond this range may not immediately fail
Therefore, the "KL SN102" is most commonly identified as a used in switched-mode power supplies (SMPS).

The plastic encapsulation is rated for -55°C to +150°C. Operating beyond this range may not immediately fail the silicon but will degrade the flame-retardant properties.
