73F683AF-RC

Fixed Inductors Overview

The Bourns Inc. 73F683AF-RC is a fixed axial leaded inductor designed for general-purpose applications. It features an inductance of 6.8 mH with a tolerance of ±5%. The component has a maximum DC current rating of 80 mA and a DC resistance of 29 Ω. It exhibits a quality factor of 95 at 250 kHz and a self-resonant frequency of 900 kHz. The device is RoHS3 compliant and supports a temperature range from -55°C to +105°C.

Fixed Inductors Feature Summary

• Axial through-hole construction for reliable mounting
• High self-resonant frequency for stable operation
• RoHS3 compliant manufacturing process

Fixed Inductors Applications

• General signal processing circuits
• Filtering applications in consumer electronics
• Power supply filtering stages

Fixed Inductors Procurement Notes

Verify the specific suffix 'RC' against the manufacturer's official datasheet to confirm compliance status and packaging details. Ensure the axial lead configuration matches the target PCB footprint requirements. Cross-reference the 6.8 mH value and 80 mA current rating with circuit design specifications to prevent saturation issues during operation.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required in a compact axial package. The 29 Ω DC resistance indicates suitability for low-current signal paths rather than high-power energy storage. Consider the 900 kHz self-resonant frequency limit when designing for higher frequency switching environments to avoid parasitic resonance effects.

Fixed Inductors Part Context

This part belongs to the Bourns 73F series of fixed inductors, which are characterized by their axial leaded form factor. The series is engineered for cost-effective solutions in standard electronic assemblies. The 73F683AF-RC specifically targets applications requiring precise inductance values with moderate current handling capabilities.

Fixed Inductors Replacement Considerations

Consult official Bourns documentation for direct cross-references. Verify that substitute parts match the 6.8 mH inductance, 80 mA current rating, and 29 Ω resistance within acceptable tolerances.
