Panel attachment
TOTX177L(F,T) has hole for panel attachment. Please be sure to attach it to panel with self
tapping
screw.
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.
Supply voltage
Use the supply voltage within the recommended operating condition (V
CC
= 5 ± 0.25 V). Make sure
that supply voltage does not exceed the maximum rating value of 7 V, even for an instant.
Input voltage
If a voltage exceeding the maximum rating value (V
CC
+ 0.5 V) is applied to the transmitters' input,
the internal IC may suffer damage. If there is a possibility that excessive voltage due to surges may
be added to the input terminal, insert a protective circuit.
(10) Soldering condition
(7)
(8)
(9)
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.
