Product Overview
EVERLIGHT 17-21_R5C-AN1P1B_3T is a Blue SMD LED built with an InGaN chip and water clear resin. It is identified as an SMD B package, with package dimensions defined by the manufacturer drawing in millimeters and general tolerances of ±0.1 mm unless otherwise noted.
At IF=20 mA and Ta=25°C, the LED is specified for 45.0 to 112.0 mcd luminous intensity, 468 nm typical peak wavelength, and 464.5 to 476.5 nm dominant wavelength. The forward voltage range is 2.7 V minimum, 3.3 V typical, and 3.7 V maximum under the same current and temperature condition. The device is not designed for reverse operation; the 5 V reverse condition applies to reverse-current testing only.
Assembly limits include 260°C for 10 seconds reflow soldering and 350°C for 3 seconds hand soldering. Tape and reel packaging uses 8 mm tape on a 7 inch reel with 3000 pieces per reel. Typical use cases include blue status indication, display lighting, compact panel indicators, and PCB-mounted visual signaling.

Procurement Notes
When requesting a quote for 17-21_R5C-AN1P1B_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.
