High Current, Surface Mount Inductor  
FEATURES  
Flame retardant encapsulant (UL 94V-0).  
Completely encapsulated winding provides superior  
environmental protection and moisture resistance.  
High current unit in surface mount package printed with  
model, inductance value and date code.  
Compatible with infrared or conventional reflow soldering  
methods.  
Pick and place compatible.  
Tape and reel packaging for automatic handling.  
APPLICATIONS  
Excellent power line noise filters, filters for switching  
regulated power supplies, DC/DC converters, SCR and  
Triac controls and RFI suppression.  
ELECTRICAL SPECIFICATIONS  
Inductance: Measured at 1 volt with no DC current.  
Inductance Tolerance: ± 15%.  
Incremental Current: The typical current at which the  
inductance will be decreased by 5% from its initial zero  
DC value.  
Operating Temperature: - 55°C to + 125°C (no load);  
- 55°C to + 85°C (at full rated current).
