HI0805R800R-01

Chip Ferrite Bead Overview

The HI0805R800R-01 is a single-line ferrite bead from the HI series, designed for power and signal line filtering. It features an 0805 (2012 metric) surface-mount package with dimensions of 2.00mm x 1.25mm x 0.90mm max height. The component provides an impedance of 80 Ohms at 100 MHz and supports a maximum current rating of 5A. Its DC resistance (DCR) is maximized at 10 milliohms. It operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides broadband EMI filtering for high-current power and signal lines
• Monolithic construction ensures reliability in surface-mount applications
• Low DC resistance minimizes voltage drop and power loss in the circuit

Chip Ferrite Bead Applications

• Power supply input/output filtering
• Signal line noise suppression
• High-current DC-DC converter stages

Chip Ferrite Bead Procurement Notes

Verify component status as this specific part number is listed as obsolete or end-of-life by major distributors. Confirm availability through authorized channels or check for direct replacements like the HI0805R800R-10 variant which may share identical electrical characteristics but differ in packaging or compliance status. Ensure sourcing partners provide valid traceability documentation.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring high current handling up to 5A with specific attenuation at 100 MHz. The 0805 footprint offers space efficiency compared to larger packages. Consider the low DCR requirement for power integrity. Evaluate thermal management capabilities given the 5A rating and operating temperature range of -40°C to 125°C.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Laird-Signal Integrity Products' HI series, which focuses on high-current chip beads. The series is engineered for broadband EMI/RFI suppression in compact electronic designs. The HI series typically utilizes monolithic technology to handle significant current loads while maintaining stable impedance characteristics across frequency ranges.

Chip Ferrite Bead Replacement Considerations

The HI0805R800R-10 is identified as a direct substitute. Verify that the suffix change does not alter RoHS compliance or other regulatory requirements if critical for your design. Electrical parameters such as impedance and current rating should remain consistent between the two variants.
