DM3312X101R-10

Chip Ferrite Bead Overview

The DM3312X101R-10 is a surface-mount ferrite bead from Laird-Signal Integrity Products, designed for EMI suppression in power and signal lines. It features a single-line configuration housed in a 3312 (8531 metric) package with dimensions of 0.134 inches by 0.126 inches (3.40mm x 3.20mm). The component provides an impedance of 100 Ohms at 100 MHz and supports a maximum rated current of 10A. Its DC resistance is specified at a maximum of 4 milliohms, ensuring minimal insertion loss while maintaining effective high-frequency noise attenuation.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference filtering for sensitive circuitry
• Supports high-current applications with low DC resistance characteristics
• Utilizes a compact surface-mount footprint for automated assembly

Chip Ferrite Bead Applications

• Power supply line filtering
• Signal line noise suppression
• High-current circuit protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix R-10 against official datasheets to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference manufacturer part numbers directly to avoid confusion with similar series components.

Chip Ferrite Bead Selection Notes

Select this component when high current handling capacity is required alongside moderate impedance values. The 10A rating distinguishes it from lower-current alternatives in the same impedance range. Evaluate thermal performance under continuous load conditions to ensure reliability within the operating temperature range.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Laird's HI/DM series of chip beads, engineered for robust performance in demanding environments. The 3312 package size offers a balance between current handling capability and board space efficiency compared to smaller footprints.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include the HI3312X101R-10, which shares identical electrical parameters and physical dimensions. Verify compatibility with existing PCB layouts before substitution.
