Overview
The Coilcraft 0805USBF-901MRC is a surface-mount common mode choke designed for high-speed signal lines. It features two channels with an inductance of 60 nH and an impedance of 300 ohms. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of unspecified low value within the series specifications. It operates within a temperature range of -40°C to +125°C and utilizes a ferrite core in an unshielded configuration.
Feature Summary
- Designed for noise suppression in ultra-high-speed signal lines
- Features high differential mode cutoff characteristics
- Complies with AEC-Q200 automotive qualification standards
Applications
- Noise suppression in USB interfaces
- High-speed data line protection
- Automotive electronic signal filtering
Procurement Notes
Verify availability through authorized distributors as supply status may vary. Confirm RoHS compliance and AEC-Q200 certification requirements against specific project needs. Ensure PCB footprint matches the 0805 package dimensions during layout design. Check for any specific handling instructions regarding the unshielded ferrite construction.
Selection Notes
Select this component when low inductance is required for high-frequency signal integrity. The 60 nH value suits applications where minimal phase shift is critical. Compare impedance at target frequencies against other series variants like 0805USB or 0805USBN. Ensure the 500 mA current rating exceeds the operational signal line current.
Part Context
This part belongs to the 0805USBF series, which focuses on low-profile solutions for space-constrained designs. It complements other Coilcraft chokes by offering specific impedance profiles for differential signaling. The series provides options for varying inductance values while maintaining consistent package dimensions for board flexibility.
Replacement Considerations
Consider the 0805USBF-902MRB for higher inductance requirements. Evaluate the 0805USB-901MLC if different thermal or current characteristics are needed. Verify pin compatibility and impedance curves before substituting with generic common mode chokes.
