2.3 inch White Alphanumeric Displays
Ultrabright white 17-segment LED displays.
No longer stocked. Please see this replacement.
This particular model is no longer stocked.
A drop-in replacement-- that features an extra decimal point LED --is available here. Big, ultrabright and beautiful 17-segment alphanumeric displays with white segments and 2.3" character height!
The segments light up in ultrabright white. Note that the white segments look yellowish when not lit. (Darn bright, real white, when lit.) Also available in ultrabright orange -- for that old school neon/nixie/panaplex look -- or ultrabright red. These are seriously bright when driven at full current, and can be placed behind a darkened window for even higher contrast viewing. A total of 53 LED elements are inside the matrix to drive the segments and decimal point. Note also that there is a black sticker on the black face of the display (which covers an unpopulated "upper decimal place" that you don't see). The internal wiring configuration is common anode. The decimal point contains a single LED element. The six "short" segments each contain two LED elements in series. The ten "long" segments each contain two LED elements in series, twice in parallel. To drive the display, we recommend using two constant-current LED driver ICs, one of which is configured for roughly 25 mA (for the six short segments and decimal), and one of which is configured for roughly 50 mA (for the long segments).
Specifications
Lead Free
These 17-segment alphanumeric displays are RoHS compliant (lead free). Working with these parts, you'll find that everything works well with either regular or lead-free solder-- whichever you care to use.
