Precautions
Please be careful of the followings.
1. Soldering temperature : 260°C max
Soldering time : 5 s max
(soldering portion of lead: at above 1.5 mm from the body of the device)
2. When forming the leads, bend each lead under the 2mm from the body of the device.
Soldering shall be performed after lead forming.
3. Do not apply stress to the leads for at least 30 s after soldering them.
4. The TLRA270 for a camera AF use only. Please do not use this device except for a camera.
