1.8mm round Subminiature Chip LED

42-21/BHC-AUW/1T

Features

․Package in 12mm tape on 7〞diameter reel.

․Compatible with automatic placement equipment.

․Compatible with infrared and vapor phase reflow

solder process.

․Mono-color type.

․Pb-free.

․The product itself will remain within RoHS

compliant version.

Descriptions

․The 42-21 SMD Taping is much smaller than lead

frame type components, thus enable smaller board

size, higher packing density, reduced storage space

and finally smaller equipment to be obtained.

․Besides, lightweight makes them ideal for

miniature applications. etc.

Precautions For Use

1. Over-current-proof

Customer must apply resistors for protection, otherwise slight voltage shift will cause big

current change ( Burn out will happen ).

2. Storage

2.1 Do not open moisture proof bag before the products are ready to use.

2.2 Before opening the package: The LEDs should be kept at 30℃ or less and 90%RH or less.

2.3 After opening the package: The LED's floor life is 1 year under 30 deg C or less and 60% RH or less.

If unused LEDs remain, it should be stored in moisture proof packages.

2.4 If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the

storage time, baking treatment should be performed using the following conditions.

Baking treatment : 60±5℃ for 24 hours.

3. Soldering Condition

3.1 Pb-free solder temperature profile

3.2 Reflow soldering should not be done more than two times.

3.3 When soldering, do not put stress on the LEDs during heating.

3.4 After soldering, do not warp the circuit board.

4.Soldering Iron

Each terminal is to go to the tip of soldering iron temperature less than 350℃ for 3 seconds within

once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering

of each terminal. Be careful because the damage of the product is often started at the time of the hand

solder.

5.Repairing

Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a

double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether

the characteristics of the LEDs will or will not be damaged by repairing.
