29F0429-0T0

Overview

The Laird-Signal Integrity Products 29F0429-0T0 is a four-line ferrite bead array designed for power line EMI filtering. It features an impedance of 245 ohms at 100 MHz and supports a maximum current rating of 8 Amperes per line. The component exhibits a maximum DC resistance of 10 milliohms. It utilizes an 8-THD through-hole package with dimensions of 0.428 inches in length and 0.216 inches in width. The device operates within a temperature range of -40°C to 125°C.

Feature Summary

• Provides differential mode noise suppression across four independent power lines
• Engineered for high-current applications with low DC resistance
• Utilizes through-hole mounting for robust mechanical attachment

Applications

• Power supply input filtering
• DC bus noise attenuation
• Multi-line power distribution protection

Procurement Notes

Verify the specific suffix (e.g., -10) required for bulk packaging when ordering, as the base part number may denote the component without specific tape-and-reel or bulk configuration details. Confirm that the 8-THD package aligns with existing PCB footprints. Ensure the 8A current rating meets the peak load requirements of the target circuit to prevent saturation or excessive heating during operation.

Selection Notes

Select this component when multi-line power filtering is required in a single footprint. The 245-ohm impedance at 100 MHz targets common high-frequency noise spectra. Compare the 10-milliohm DCR against voltage drop constraints in the power path. The through-hole format is suitable for prototyping or high-vibration environments where surface mount options are less desirable.

Part Context

This component belongs to the 29F Series of ferrite differential mode arrays from Laird-Signal Integrity Products. These arrays offer an economical solution for suppressing electromagnetic interference in multi-conductor power cables. The series is characterized by high current handling capabilities and standardized impedance values for various frequency ranges.

Replacement Considerations

Check for direct substitutes within the 29F series offering similar 245-ohm impedance and 8A ratings. Verify pin compatibility for 8-THD packages before substituting with other manufacturers' multi-line ferrite beads.
