Please note:
1. Storage
Storage conditions or environment may adversely a󰀨ect solderability of the exterior terminals. Do not store in
high temperature and humidity. The recommended storage environment is lower than 40°C, has less than 70%
RH humidity and is free from harmful gases such as sulphur and chlorine.
2. Caution in Soldering
- IR and vapor phase reow are recommended.
- Vacuum pick up is recommended for handling.
- If the use of a soldering iron becomes necessary, precautionary measures should be taken to avoid any possi-
ble damage / overheating.
3. Cleaning
Avoid the use of cleaning agents which could attack epoxy resins, which form part of the resistor construction.
4. Recommended Land Pattern
The dimensions of solder land must be determined in conformity with the size of resistors and with the soldering
method. They are also subject to the mounting machine and the material of the substrate.
