■ Lot number
ᆞThe first five digits number shows lot number.
ᆞThe lot number is composed of the following characters;
Day ( 01,02,…,29,30,31 )
Month ( 1,2,3….9,A,B,C )
Year ( 03,04,…10 )
ㆍWhen washing is required, isopropyl alcohol should be used.
ㆍThe influence of ultrasonic cleaning on the optical detectors differs depending on factors such
as oscillator output and how the optical detectors are mounted. Before cleaning by ultrasonic
wave, testing should be performed to ensure this will not cause damage to the optical detectors.
ᆞThe optical detectors should be stored at 30℃ or less and 70%R.H or less after being shipped
from ODTech and the storage life limits are 3 months. If the optical detectors are stored for 3
months or more, they can be stored for a year in a sealed container with a nitrogen atmosphere
and moisture absorbent material.
ᆞODTech optical detectors leads are comprised of a gold plated iron alloy. The gold surface may
be affected by environments which contain corrosive gases and so on. Please avoid conditions
which may cause the device to corrode, tarnish or discolor. This corrosion or discoloration may
cause difficulty during soldering operations. It is recommended that the optical devices be used
as soon as possible.
ᆞPlease avoid rapid transitions in ambient temperature, especially, in high humidity environments
where condensation can occur.
