Reliability Testing
Refer to detailed specifications in the original document for specific test items, requirements, and methods including Terminal Strength, Resistance to Flexure, Dropping, Solderability, Vibration, Thermal Shock, Low temperature Storage, High temperature Storage, Damp Heat, Heat endurance of Reflow soldering, Resistance to solvent, Overload, and Voltage resistance tests.
Recommended Reflow Soldering Curve
The recommended reflow conditions should be adjusted and confirmed according to the user's environment and equipment.
Reminders for Using These Products
- Storage: within 12 months, under 5~40C and 35~65% RH.
- Avoid use and storage in corrosive environments.
- Handle with care to avoid damage from dropping.
- Do not bend terminals excessively.
- Do not clean coils; contact manufacturer if necessary.
- Keep away from magnets or magnetic fields.
- Preheat components before soldering; temperature difference should not exceed 150C.
- Consider self-heating during operation for thermal design.
- For non-magnetic shield types, careful coil placement is needed to avoid malfunction due to magnetic interference.
