Recommended Soldering Conditions

  • Reflow Soldering: Products can be applied to reflow soldering. Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited to 150 max. Cooling into solvent after soldering should be limited to 100 max.
  • Iron Soldering: Soldering Iron Temperature: 350 (Max); Power: 30W (Max); Soldering Time: < 5S (Take care not to apply the tip of the soldering iron to the terminal electrodes).

Cleaning Conditions

  • Cleaning Temperature: 60 max
  • Cleaning Time: 1 minute min.
  • Ultrasonic output power: 200W max

Storage Requirements

  • Storage Period: Within 1 year from the inspection date at the inductor company. If the period is exceeded, solder ability should be checked before use.
  • Storage Conditions: Temperature: -10 to +40, Relative Humidity: 30% to 70%. Avoid storage in corrosive gases. Store on a palette to prevent influence from humidity and dust. Avoid heat shock, vibration, and direct sunlight. Products should be stored under airtight packaged condition.

Usage Of ODS (Ozone Depleting Substances)

The company does not use ODS such as CCl4 (carbon tetrachloride) and HCFC in the production process.
