Recommended Soldering Profile: Reflow soldering is recommended. Use rosin-based flux (halide content < 0.2wt%) and lead-free solder (96.5Sn/3.0Ag/0.5Cu). Temperature difference between solder and ferrite surface during pre-heating should not exceed 150. Cooling difference into solvent after soldering should not exceed 100. Soldering should be performed within the allowable range indicated by the profile curve.
Manual Soldering: Iron temperature: 350 (Max), Power: 30W (Max), Soldering Time: < 5S. Avoid touching coils or encapsulation layer.
Cleaning Conditions: Cleaning temperature: 60 (Max), Cleaning time: 5 minutes (Max), Ultrasonic power: 200W (Max).
Storage Requirements:
- Storage Period: Use within 6 months from the inspection date. If exceeding 6 months, check solderability before use.
- Storage Conditions: Temperature: -10 ~ +40, Relative Humidity: 30 ~ 70%. Store away from corrosive substances. Keep on shelves, protected from moisture, dust, heat shock, vibration, and direct sunlight. Store in airtight packaging.
Usage Of ODS (Ozone Depleting Substances): CCl4, HCFC, etc. are not used in the production process.
