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. STANDARD ELECTRICAL SPECIFICATIONS
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. DIMENSIONS in inches [millimeters] 3.9µH INDUCTANCE VALUE IHSM-3825 MODEL
