Red SMD LED 0603 - Inolux IN-S63BTR

Inolux Corporation IN-S63BTR: 0603 SMD Red LED, 2.2 V drop, 25 mA max. An Adom Basic Part: Adom keeps it on reels for its pick-and-place line, so boards built with it draw on Adom stock.

Notes for designers

IN-S63BTR is the red member of Inolux's IN-S63BT series: a low-profile 0603 top-view indicator LED in a clear, PCB-type moulded package. (p.1) Electrically it is an unremarkable AlInGaP red emitter (p.8), dominant wavelength 622 nm (p.3), which is the point: it is the part you reach for when a board needs a power or status light and nothing about the light itself should be interesting.

Budget 2.2 V across it at the 20 mA test point and it returns 140 mcd. (p.3) Drive it through a current-limiting resistor rather than straight off a rail, the datasheet says so explicitly (p.13), and keep continuous current at or below 25 mA. (p.2) At 3.3 V that is a (3.3 − 2.2) / 0.02 = 55 Ω resistor for the full 20 mA, and most indicators are happier an order of magnitude dimmer than that.

Two limits are tighter than instinct suggests. Peak pulse current is only 70 mA (1/10 duty, 0.1 ms) for the AlInGaP colours, the InGaN members of the same series get 100 mA (p.2), so check this row, not the series headline, before multiplexing. And reverse voltage is rated to only 5 V, (p.2) well under a 12 V rail, so it must never be left reverse-biased across one. The 120° viewing angle (p.3) makes it a wide-angle panel indicator, not a directional source.

Footprint

Redrawn from the datasheet land pattern (the previous pads were off by up to 0.5 mm).

Source: Land pattern from Inolux IN-S63BT series datasheet V1.2, p.1 (Recommended Solder Pattern).

mm	Datasheet	KiCad standard (LED_0603_1608Metric)	Previous	This page
Pad length (along the part)	0.6	0.875	0.9	0.6
Pad width	0.9	0.95	1	0.9
Gap between pads	0.8	0.7	0.7	0.8
Centre to centre	1.4	1.575	1.6	1.4
Overall	2	2.45	2.5	2
Corner radius	not specified	0.2188 (ratio 0.25)	0.225 (ratio 0.25)	square (as drawn)
Corners: square, as the datasheet draws them. The datasheet does not call for rounded corners, so the footprint does not add any.

Polarity: pad 1 = K (cathode, -X), pad 2 = A, matching the symbol (K = pin 1, A = pin 2) and the datasheet's cathode mark; the silkscreen bracket marks the cathode end.

Chip outline

The part's 3D outline in the standard pose (pad 1 toward the viewer), drawn from the STEP by Adom's OpenCascade service; the part number sits where the laser-etched mark is on the 3D model and reads the same way.

Symbol options

The default symbol, IN-S63BTR.kicad_sym (the one in the Symbol & Footprint panel), is the plain standard symbol. IN-S63BTR-outline.kicad_sym is the same symbol with the part's 3D chip outline drawn beside it, its part number placed and reading as on the 3D model.

Footprint: Land pattern from Inolux IN-S63BT series datasheet V1.2, p.1 (Recommended Solder Pattern). Pads redrawn on 2026-10-03.
3D model and symbol: unchanged by the footprint pass; the etched STEP adds a flat virtual part-number mark (an identification aid, not the maker's marking).
