XFEB100505-121-0.5A

Overview

The XFEB100505-121-0.5A is a single-line ferrite bead component manufactured by XFMRS, designed for high-frequency noise suppression in electronic circuits. It features a compact 0402 (1005 Metric) surface-mount package with physical dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The device provides an impedance of 120 Ohms at a frequency of 100 MHz. It supports a maximum DC current rating of 500 mA and exhibits a low DC resistance of 250 mOhm, ensuring minimal signal attenuation while effectively filtering electromagnetic interference.

Feature Summary

• Provides effective high-frequency noise attenuation through controlled impedance characteristics
• Utilizes a compact surface-mount form factor suitable for space-constrained PCB layouts
• Maintains low DC resistance to minimize power loss and voltage drop in the circuit path

Applications

• Signal line filtering in portable consumer electronics
• Noise suppression on data transmission interfaces
• Power rail decoupling in compact digital devices

Procurement Notes

Verify the specific impedance value and current rating against the project requirements before ordering. Confirm that the 0402 package size aligns with the available footprint on the printed circuit board. Ensure the supplier provides authentic components from the XFMRS manufacturing line to guarantee consistent electrical performance and reliability in final assembly.

Selection Notes

Select this component when a small footprint is required for noise filtering applications operating up to 100 MHz. The 500 mA current rating makes it suitable for low-power signal lines rather than high-current power distribution paths. Consider the 250 mOhm DC resistance impact on overall circuit efficiency during the design phase to ensure compatibility with sensitive signal sources.

Part Context

This ferrite bead belongs to the XFEB100505 series, which utilizes a standardized metric case code indicating its physical dimensions. The suffix '121' denotes the specific impedance characteristic at the reference frequency, while '0.5A' specifies the rated current capacity. This nomenclature allows engineers to quickly identify the electrical properties and physical constraints within the broader family of XFMRS passive components.

Replacement Considerations

Substitute parts must match the 0402 package dimensions, 120 Ohm impedance at 100 MHz, and 500 mA current handling capability. Verify that alternative manufacturers offer comparable DC resistance values to maintain circuit performance integrity.
