# KT-0603Y

**Hubei KENTO Elec** · LED, yellow · 0603 (1608 metric)

Hubei KENTO yellow indicator LED in an 0603 package with a water-clear lens: 584 to 594 nm dominant wavelength, 120 degree viewing angle. Sibling of the KT-0603R, KT-0603G and KT-0603B pages.

## Verification

A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode. Marked (2) with the green corner mark on the datasheet drawing (p.2). |
| 2 | A | passive | Anode. Marked (1) and + on the datasheet drawing (p.2). Use a series resistor. |

**Note:** KiCad numbers the cathode pad 1; the datasheet labels the same terminal (2). The polarity is what matters: the cathode mark sits over KiCad pad 1.

## CAD

| File | What it is |
|---|---|
| `kt-0603y.kicad_sym` | KiCad symbol, with MPN, manufacturer and distributor numbers as properties |
| `kt-0603y.kicad_mod` | KiCad footprint: `LED_SMD:LED_0603_1608Metric`, KiCad official, CC-BY-SA 4.0 |
| `kt-0603y.step` / `kt-0603y.glb` | 3D model, Z-up, seated on z = 0: KiCad packages3D (tag 10.0.6), LED_0603_1608Metric.step |
| `kt-0603y.lbr` | Fusion 360 / EAGLE library: one deviceset, each with its own MPN, manufacturer and LCSC / Mouser / DigiKey attributes |
| `altium/Adom_kt_0603y.SchLib` / `.PcbLib` | Altium library pair (adom-lbr, no Altium needed): symbol and footprint with the 3D body, parameters carry the part numbers; `altium/*.adom-lbr.json` is the canonical hub each was built from |
| `states.json`, `states/` | Off and lit models (STEP and GLB) and a picture of each, for viewers and the probing simulator. Lit = only the lens (the clear top block) turns 589 nm yellow and glows (an emissive material in the GLB); the base and terminals stay as they are. |
