Product Overview
17-21_GHC-XS1T2M_3T is an EVERLIGHT blue SMD LED built with an InGaN chip and water clear resin. It is identified as a 17-21 SMD B package device, with package dimensions shown in the manufacturer datasheet although numeric package dimensions are not present in the provided extracted text.
Electrical ratings at Ta=25°C include 20 mA forward current, 40 mA peak forward current under duty 1/10 at 1 kHz, 75 mW power dissipation, and 5 V reverse-voltage test conditions. The datasheet notes that the device is not designed for reverse operation; the reverse-voltage condition applies to reverse-current testing only.
Optical characteristics at IF=20 mA and Ta=25°C include 45.0 to 112.0 mcd luminous intensity, 468 nm typical peak wavelength, 464.5 to 476.5 nm dominant wavelength, 25 nm typical spectrum radiation bandwidth, and 140° typical viewing angle. Assembly and handling data include 8 mm tape on a 7 inch reel, 3000 pieces per reel, up to two reflow passes, and defined floor-life and baking conditions after opening.

Procurement Notes
When requesting a quote for 17-21_GHC-XS1T2M_3T, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
