8. Precautions on Use

(1) Maximum rating

The maximum ratings are the limit values which must not be exceeded during operation of device.

None of these rating value must not be exceeded. If the maximum rating value is exceeded, the

characteristics of devices may never be restored properly. In extreme cases, the device may be

permanently damages.

(2) Soldering

Optical modules are comprised of internal semiconductor devices. However, in principle, optical

modules are optical components. During soldering, ensure that flux does not contact with the emitting

surface or the detecting surface. Also ensure that proper flux removal is conducted after soldering.

Some optical modules come with shutter system. The shutter is closed to avoid malfunction when the

optical module is not in use. Note that it is not dust or waterproof.

As mentioned before, optical modules are optical components. Thus, in principle, soldering where

there may be flux residue and flux removal after soldering is not recommended. Toshiba recommend

that soldering be performed without the optical module mounted on the board. Then, after the board

has been cleaned, the optical module should be soldered on to the board manually.

If the optical module cannot be soldered manually, use non−halogen (chlorine−free) flux and make

sure, without cleaning, there is no residue such as chlorine. This is one of the ways to eliminate the

effects of flux. In such a cases, be sure to check the devices' reliability.

(3) Noise resistance

It is believed that the use of optical transfer devices improve noise resistance. In theory, optical fiber

is not affected by noise at all. However, receiving modules which handle signals whose level is

extremely small, are susceptible to noise.

TOSLINK improve noise resistance to use a conductive case. However, the current signal output by

the optical receiving modules' photodiode is extremely small. Thus, in some environments, shielding

the case may not achieve sufficient noise resistance.

For systems which incorporate TOSLINK, Toshiba recommend testing using the actual device to

check its noise resistance.

Use a simple noise filter on TOSLINK fiber optic transceiving module's power line. If the ripple in the

power supply used is significant, reinforce the filter.

The optical module is to be used in an area which is susceptible to radiated noise, increase the

shielding by covering the optical module and the power line filter with a metallic cover.

(4) Vibration and shock

This module is plastic sealed and has its wire fixed by resin. This structure is relatively resistant to

vibration and shock. In actual equipment, there are sometime cases in which vibration, shock, or

stress is applied to soldered parts or connected parts, resulting in lines cut. A care must be taken in

the design of equipment which will be subject to high levels of vibration.

(5) Support pins

The TORX147L(F,T) has support pins in order to fix itself to the PCB temporary. Please make the

hole for these pins in the PCB under the condition described in board layout hole pattern.

(6) Panel attachment

TORX147L(F,T) has hole for panel attachment. Please be sure to attach it to panel with self−tapping

screw.

(7) Solvent

When using solvent for flux removal, do not use a high acid or high alkali solvent. Be careful not to

pour solvent in to the optical connector ports. If solvent is inadvertently poured in to them, clean it off

using cotton tips.

(8) Supply voltage

Use the supply voltage within the recommended operating condition (VCC = 2.7 to 3.6V). Make sure

that supply voltage does not exceed the maximum rating value of 4.5 V, even for an instant.

(9) Output

If the receiver output is at low and is connected to the power supply, or if the output is high and is

connected to GND, the internal IC may be destroyed.

(10) Soldering condition

Solder at 260°C or less for no more than ten seconds.

(11) The hole for chassis

Please make a hole for inserting optical connector

the slash part in the following figure.

(12) Case(receptacle) material

The case is made of polycarbonate. Polycarbonate is usually stable with acid, alcohol, and

aliphatic hydrocarbons however, with petrochemicals (such as benzene, toluene, and acetone),

alkali, aromatic hydrocarbons, or chloric hydrocarbons, polycarbonate becomes cracked, swollen,

or melted. Please take care when choosing a packaging material by referencing the table below.
