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.
