DESCRIPTION

These T-100 LEDs are used as general purpose indi-

cators. They come in either a wide angle (70°) dif-

fused lens or a moderate angle (32°) clear lens. The

red and green lamps are made with GaP LEDs on a GaP sub-

strate. The HER and yellow lamps are made with GaAsP LEDs on

a GaP substrate. All have an epoxy encapsulation lens.

FEATURES

• Popular T-100 package

• Choice of viewing angles

• Choice of tinted or tinted diffused lens

NOTES:

1. Dimensions for all drawings are in inches (mm).

2. Lead spacing is measured where the leads emerge from the

package.

3. Protruded resin under the flange is 1.5 mm (0.059") max.

4. Tolerance is +/-0.12” (0.3mm) unless otherwise noted.
