29F0428-0T0-10

Overview

The 29F0428-0T0-10 is a four-line ferrite bead component manufactured by Laird-Signal Integrity Products. It features an 8-terminal through-hole (THD) package designed for power line applications. The device provides an impedance of 342 Ohms at 100 MHz and supports a maximum current rating of 10 Amperes. Its DC resistance (DCR) is specified as a maximum of 10 milliohms. This component is engineered to suppress electromagnetic interference in multi-line power distribution systems.

Feature Summary

• Four independent filtering channels integrated into a single component
• Through-hole mounting configuration for robust mechanical attachment
• High current handling capability suitable for power line protection

Applications

• Multi-phase power supply input filtering
• Electromagnetic interference suppression in industrial equipment
• Signal integrity management in high-current DC circuits

Procurement Notes

Verify the specific terminal count and package style against your PCB footprint requirements, as datasheets may vary between 4-line and 5-line descriptions. Confirm the exact impedance value at 100 MHz matches your EMI filter design specifications. Ensure the through-hole pin layout aligns with your assembly process capabilities before finalizing procurement decisions.

Selection Notes

Select this component when multi-line power filtering is required in a compact through-hole form factor. The low DC resistance minimizes voltage drop across the filter under high load conditions. Consider the thermal performance and current derating curves if operating near the 10A limit in enclosed environments or elevated ambient temperatures.

Part Context

This part belongs to Laird-Signal Integrity Products' ferrite bead and chip series, specifically designed for power line applications. The 29F series typically offers multi-channel solutions for complex power distribution networks. These components are distinct from surface-mount beads, offering higher current capacity and mechanical stability for through-hole implementations.

Replacement Considerations

Direct substitutes include the 29F0528-0T0-10, which shares similar electrical characteristics but may differ in line count or physical dimensions. Verify that any replacement maintains the same 342 Ohm impedance at 100 MHz and 10A current rating to ensure circuit compatibility.
