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.
