PACKAGE DIMENSIONS

L-57EYW

T-1 3/4 (5mm) Bi-Color Indicator Lamp

Notes:

1. All dimensions are in millimeters (inches).

2. Tolerance is ±0.25(0.01") unless otherwise noted.

3. Lead spacing is measured where the leads emerge from the package.

4. The specifications, characteristics and technical data described in the datasheet are subject to change

without prior notice.

SELECTION GUIDE

Notes:

1. θ1/2 is the angle from optical centerline where the luminous intensity is 1/2 of the optical peak value.

2. Luminous intensity / luminous flux: +/-15%.

* Luminous intensity value is traceable to CIE127-2007 standards.

L-57EYW PACKING & LABEL SPECIFICATIONS t h g i r b PRECAUTIONS Storage conditions 1. Avoid continued exposure to the condensing moisture environment and keep the product away from rapid transitions in ambient temperature. 2. LEDs should be stored with temperature ≤ 30°C and relative humidity < 60%. 3. Product in the original sealed package is recommended to be assembled within 72 hours of opening. Product in opened package for more than a week should be baked for 30 (+10/-0) hours at 85 ~ 100°C.

L-57EYW Lead Forming Procedures 1. Do not bend the leads more than twice. (Fig. 6 ) 2. During soldering, component covers and holders should leave clearance to avoid placing damaging stress on the LED during soldering. (Fig. 7) 3. The tip of the soldering iron should never touch the lens epoxy. 4. Through-hole LEDs are incompatible with reflow soldering. 5.
