Post by thread:[OT] Looking for a 7-seg display

I'm looking for a 3-digit 7-seg display with a 0.3" character height or greater, but with a package size no greater than ~1"W x ~0.5"H. Thickness (height above PCB) of display is not important. Through-hole (as SMD displays don't seem to work in this case). Red color, though it would be nice if also available in other colors with the same pinout. CC preferred, though I can work with CA. Currently I'm using 3 single-digit displays (LSHD-A103), but the pin-count is eating up PCB space and threatening me to go to a 4-layer PCB (which I really want to avoid). Any sources? So far I've not found anything suitable thru Digikey, Mouser, or SunLED. Thanks, -Neil.

And I'm still quite convinced that Kingbright is in cohorts with SunLED, as their datasheets, specs, etc are almost identical. Thanks, -Neil.

These ones seem close to what you're asking except slightly over 0.5" high. www.forge-europa.co.uk/pdfs/FN3-036XX00GW.pdf www.forge-europa.co.uk/forge/more-detail/triple-digit-seven-segment- displays-tech.asp Brent. -- Brent Brown, Electronic Design Solutions 16 English Street, St Andrews, Hamilton 3200, New Zealand Ph: +64 7 849 0069 Fax: +64 7 849 0071 Cell: +64 27 433 4069 eMail: .....brent.brownKILLspam@spam@clear.net.nz

But meets the rest of your requirements.

Dimensionally, if the existing displays meet your size requirement and if height above PCB is unconstrained, this gives you an ideal solution. Suboptimal in other respects though. Russel

Suboptimal in other respects though. But may allow more optimal tracking on the main PCB by being able to have connections from piggy back display board come down at suitable places - they don't all have to be in a row on the edge ... -- Scanned by iCritical.

This is actually beautiful! By "height", I meant height above the PCB, which is 5mm here, so it looks like it will work beautifully. Thanks, -Neil.
