Product Overview
EVERLIGHT 17-21_R6C-AP1Q1B_3T is a blue SMD LED built with an InGaN chip and water-clear resin. The device is supplied in the 17-21 SMD-B package, with package dimensions defined in millimeters and drawing tolerances of ±0.1 mm unless otherwise specified.
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, 464.5 to 476.5 nm dominant wavelength, and 25 nm typical spectrum radiation bandwidth. Forward voltage is listed as 2.7 V minimum, 3.3 V typical, and 3.7 V maximum under the same current and temperature condition.
Assembly data includes 8 mm tape on a 7 inch reel with 3000 pieces per reel. Reflow soldering is rated at 260°C for 10 seconds, with no more than two reflow cycles. After opening, storage is specified at 30°C or less and 60%RH or less for 168 hours / 7 days.

Procurement Notes
When requesting a quote for 17-21_R6C-AP1Q1B_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.
FAQ
What color does 17-21_R6C-AP1Q1B_3T emit?
17-21_R6C-AP1Q1B_3T is specified as a blue SMD LED. The datasheet lists blue emitted color, InGaN chip material, water-clear resin, 468 nm typical peak wavelength, and 464.5 to 476.5 nm dominant wavelength at IF=20 mA.
What current and voltage ratings apply to this LED?
The absolute maximum forward current is 20 mA at Ta=25°C, with 40 mA peak forward current at duty 1/10 and 1 kHz. Forward voltage at IF=20 mA is specified as 2.7 V minimum, 3.3 V typical, and 3.7 V maximum.
Can this device be used in reverse operation?
No. The datasheet states that the device is not designed for reverse operation. The 5 V reverse-voltage condition applies to the reverse-current test only, where reverse current is specified as 50 µA maximum at VR=5 V.
What assembly storage conditions are specified after opening?
After opening the package, storage is specified at 30°C or less and 60%RH or less. The floor life is 168 hours, or 7 days. If silica gel has faded or storage time is exceeded, baking is specified at 60±5°C for 24 hours.
