4) Vibration and shock
This module is resin-molded construction with wire fixed by resin. This structure is relatively sound against
vibration or shock. In actual equipment, there are some cases where vibration, shock, and stress is applied
to soldered parts or connected parts, resulting in line cut. Attention must be paid to the design of the
mechanism for applications which are subject to large amounts of vibration.
5) Fixing fiber optical transceiving module
Solder the fixed pin of fiber optic transmitting module APTX179XX to the printed circuit board to fix the
module to the board.
6) Solvent
When using solvent for flux removal, do not use a high acid or high alkali solvent. Be-careful not to pour
solvent in the optical connector ports. If solvent is inadvertently poured there, clean with cotton tips.
7) Protective cap
When the fiber optic transmitting module APTX179XX is not in use, use the protective cap.
8) Supply voltage
Use the supply voltage within the Typ. Operating condition (Vcc = 5
±
0.25V). Make sure that supply voltage
does not exceed the maximum rating value of 7V, even instantaneously.
9) Input voltage
If a voltage exceeding the maximum rating value (Vcc+0.5V) is applied to the transmitter Input, the internal
IC may degrade causing some damage. If excessive voltage due to surge may be added to the input, insert
a protective circuit.
10) Soldering condition
Solder at 240
o
C within ten seconds.
11) Precaution on waste
When discarding devices and packing materials, follow procedures stipulated by local regulations in order to
protect the environment against contamination.
Compound semiconductors such as GaAs are used as LED materials for this module. When discarding
waste or at final processing, attention must be paid to workers and the environment.
12) Precaution on use
Ampson is continually working to improve the quality and the reliability of its products.
Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical
sensitivity and vulnerability to physical stress. It is the responsibility of the buyer, when utilizing Ampson
products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a
Ampson product could cause loss of human life, bodily injury or damage to property.
In developing your designs, please ensure that Ampson products are used within specified operating ranges
as set forth in the most recent product specifications.
