Description
ONE Lot 25 DUAL YELLOW 7-segment LED displays. Made by HP (AVAGO), part number HDSP-5721 / QDSJ-K003.Unused, New Old Stock parts, from the original tubes.
0.56" Character Height.
These are Common Anode and have RH decimal points on both displays
These are End Stackable (abuttable) in both directions (see pics)
From the spec sheet:
20ma max DC current per segment (60ma peak pulsed - 1ms @ 1kHz).
Vf = 2.1V typ / 2.5V max @ If = 20ma
Luminous Intensity = 1800ucd typ @ If = 10ma
Peak Wavelength = 583nm
Dominant Wavelength = 581.5nm min / 586nm typ / 592.5nm max
AlGaAs LED material
+/- 50-degree viewing angle
Operating Temperature = -40 degrees-C to +100 degrees-C
Outer Dimensions: 0.990" (25.146mm) x 0.673" (17.02mm) x 0.315" (8.00mm) - excluding leads
Lead Length ~0.155" (3.95mm)
Display Dimensions (each): 0.560" (14.22mm) x 0.307" (7.80mm) - [approx. 0.85" length for both digits End-to-End]
Package has 18-pins with 0.1" lead spacing and 0.6" across the package.
Note: Each digit is pinned out ~separately~ (i.e., non-multiplexed) so there are 9-pins per each digit (7-segments
plus one decimal point plus the common anode) for a total of 18. Of course, you can wire it up to operate as a
multiplexed display if you wished.
These are not super bright and have more of a yellow-orange color than pure yellow. But not bad displays at all.
The pic i made in the dark seems to appear a bit more yellow than it actually appears for some reason. The pic was made
using only ONE 330-ohm resistor powering ALL 8-LEDs at 5V so not the typical way the display is normally used and it will
normally be brighter. Of course, i was also only powering it with about 1/4 of the max 20ma/segment current too.
Will ship in a USPS 1st class priority mail Flat Rate padded Envelope or Small/Medium/Large Flat Rate box, depending on the quantity.
Note: I will transfer the parts from the tubes to plastic baggies to save on shipping. The parts will not be harmed at all.
