Description

The M5003 is CMOS chip design for Electro-luminescence Lamp (EL) to light has independent circuit to control switching and EL driver frequency circuit, The switching frequency is decided by CKX, If OSC connect a resistor to VDD, or connect a capacitor to VSS the switching frequency can be adjusted. Delay function can be implement if ON connect a capacitor to VSS. The time of delay is decided by the value of capacitor.

LT5234 pinout datasheet

Description

This yellow lamp is made with GaAsP/GaP chip and yellow clear epoxy resin.

 

Absolute Maximum Ratings at Ta=25°C

1. Power Dissipation : PD  = 78 mW

2. Reverse Voltage : VR = 5 V

3. D.C. Forward Current : If = 30 mA

4. Reverse (Leakage) Current : Ir = 100 uA

5. Operating Temperature Range : Topr = -25 to +85 ℃

6. Storage Temperature Range : Tstg = -40 to +100 ℃

 

Temperature in use :

Since the light generated inside the LED needs to be emitted to outside efficiently, a resin with
high light transparency is used; therefore, additives to improve the heat resistance or moisture
resistance (silica gel , etc) which are used for semiconductor products such as transistors
cannot be added to the resin.
