Cautions for using this product
1. When soldering terminals, there is a danger that load placed on the terminals may cause rattle, deformation or
electrical degradation to occur depending on the conditions. Caution is therefore required.
2. Avoid use of water-soluble soldering flux, since it may corrode the product.
3. Check and conform to reflow soldering requirements under actual mass production conditions.
4. PC board warping may alter the characteristics. Please take this into consideration when designing patterns and
layout.
5. The card specifications are provided by the above manufactures. Products by other manufactures may not be
compliant with these specifications and are subject to change without prior notice.
