## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode electrode, marked by the cathode index on the top of the package (left electrode in Figure 1); the LED is rated for 5V maximum reverse voltage and 20mA forward current. |
| 2 | A | passive | Anode electrode, opposite the cathode index (right electrode in Figure 1); the LED is rated for 20mA forward current (100mA peak at duty 1/10, 1kHz) with VF of 2.2V typ and 2.7V max at IF=20mA. |
