Overview
The Coilcraft 0805USBF-502MRC is a single-channel common mode filter designed for high-speed signal lines. It features an inductance of 560 nH and a DC resistance of 0.63 ohms. The component operates within a temperature range of -40°C to +125°C and supports a maximum DC current of 350 mA. It utilizes a ferrite core and is housed in an unshielded 0805 surface-mount package.
Feature Summary
- Engineered specifically for filtering common mode noise on high-speed signal lines
- Utilizes a ferrite core material for effective electromagnetic interference suppression
- Constructed with an unshielded design suitable for standard PCB mounting
Applications
- High-speed USB data line protection
- Signal integrity enhancement in digital communication interfaces
- Common mode noise reduction in portable electronic devices
Procurement Notes
Verify the complete part number including the suffix MRC to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any specific handling requirements related to the ferrite core material during assembly processes.
Selection Notes
Select this component when designing circuits requiring common mode filtering for high-speed signals with moderate current demands. Ensure the 0805 footprint aligns with the target PCB layout constraints. Verify that the 350 mA current rating meets the operational requirements of the specific signal line being protected.
Part Context
This component belongs to the 0805USBF series, which focuses on low-profile solutions for signal line applications. It shares the 0805 form factor with other Coilcraft filters but differs in inductance values and current ratings compared to variants like the 0805USB or 0805USBN series.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official Coilcraft documentation for potential cross-references or updated product recommendations.
