Definitions
- Saturation Current: DC current at which inductance drops 30% from its value without current.
- Heat Rating Current: The actual value of DC current when the temperature rise is T 40 (Ta=25).
- Rated DC Current: The lesser value between Isat and Irms.
Reminders for Using These Products
- Storage: Within 12 months, under conditions of 5~40C and 35~65% RH. Terminal solderability may deteriorate beyond this period.
- Environment: Avoid use and storage in corrosive gas environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions that can inhibit soldering. Handle products carefully to prevent damage.
- Terminal Bending: Do not excessively bend terminals to avoid wire fracture.
- Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or strong magnetic fields.
- Preheating: Preheat components before soldering. The temperature difference between solder and chip temperature should not exceed 150C.
- Soldering Corrections: Post-mounting soldering corrections must be within specified conditions. Overheating can cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Account for self-heating when power is applied; ensure sufficient thermal design margin.
- Non-Magnetic Shield Type: Careful coil placement is required in PCB design to prevent malfunctions due to magnetic interference.
