Definitions
- Saturation Current (Isat): DC current at which inductance drops 10% from its value without current.
- Temperature Rise Current (Irms): The actual value of DC current when the temperature rise is T 40 (Ta=25).
- Rated DC Current: The lesser value of Isat or Irms.
Usage Reminders
- Storage period is within 12 months under conditions (temperature: 5~40C, humidity: 35~65% RH or less).
- Avoid use and storage in gas corrosive environments (salt, acid, alkali, etc.).
- Do not touch electrodes directly with bare hands.
- Handle products carefully to prevent damage.
- Do not bend terminals excessively.
- Do not rinse coils; contact the manufacturer if cleaning is required.
- Do not expose products to magnets or magnetic fields.
- Preheat components before soldering; temperature difference between solder and chip should not exceed 150C.
- Soldering corrections after mounting should be within specified conditions to avoid overheating.
- Allow sufficient margin for thermal design due to self-heating when power is on.
- For non-magnetic shield types, careful coil layout on the PCB is necessary to prevent malfunctions due to magnetic interference.
