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).
MATERIAL SPECIFICATIONS
Core: High resistivity ferrite core.
Encapsulant: Epoxy.
Terminals: 60/40 solder coated copper.
