Precautions for use：

1. When installing the core, the product structure design should fully consider the impact of the installation stress. A nylon washer should be installed on the lead surface of the core to make the core evenly stressed and avoid zero point instability.

2. Before soldering the leads, please preheat the core body to increase the solderability of the solder joints and prevent the solder joints from being heated for a long time to reduce the adhesion of the bonding pads.

3. Do not scratch the paint film. Scratching the blue film will damage the internal circuit, which may cause unstable performance.

4. For detailed parameters, please refer to the specific product specification acknowledgement.

Remarks: *Our product graphics have applied for patent protection.

*All our products adopt the laser on-line warming process except for special indications.
