(5mm) Modified Ultra Bright
AlGaAs Red LED Lamps
LTL-353URKR
LTL-353CKR
Features
Ultra brightness.
New sturdy leads.
Versatile mounting on P.C. board or panel.
I.C. compatible/low current requirements.
Reliable and rugged.
Package Dimensions
Description
The source color devices are made with Aluminum
Gallium Arsenide light emitting diode.
LTL-353URKR is made with high performance AlGaAs
dice.
LTL-353CKR is made with DH AlGaAs dice.
The devices are made with water clear epoxy package,
and with 12 degrees of viewing angle.
These Ultra bright lamps out perform convential LED
lamps.
By utilizing new higher intensity material, we achieve
superior product performance.
Notes:
1. All dimensions are in millimeters (inches).
2. Tolerance is
0.25mm (.010") unless otherwise noted.
3. Protruded resin under flange is 1.0mm (.04") max.
4. Lead spacing is measured where the leads emerge from
the package.
5. Specifications are subject to change without notice.

Notes:1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE eye-response curve.
2. Luminous intensity rank classified products support two ranks.
3.

6. The dominant wavelength, d is derived from the CIE chromaticity diagram and represents the single wavelength which
defines the color of the device.
