DESCRIPTION

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.
