BCAS100505A221

Overview

The BCAS100505A221 is a multilayer high-frequency ferrite bead from the Max Echo BCAS series, designed for noise suppression in signal lines. It features a 0402 (1005 Metric) package with dimensions of 1.00mm x 0.50mm. The component provides an impedance of 220 Ohms at 100 MHz and has a maximum DC resistance of 700mOhm. It supports a rated current of 200mA and is intended for GHz working frequencies.

Feature Summary

• Designed to address high-frequency noise suppression needs using breakthrough printing technology
• Optimized for small form factor applications in GHz working frequencies

Applications

• High-frequency noise suppression in signal lines
• EMI suppression in compact electronic circuits

Procurement Notes

Verify the specific impedance value and DC resistance against the official Max Echo datasheet for the BCAS100505A221 part number. Confirm that the 0402 package size and 200mA current rating match your circuit requirements. Ensure compatibility with your manufacturing process for tape and reel packaging.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise filtering. The 0402 footprint allows for dense PCB layouts. Consider the 220 Ohm impedance at 100 MHz to ensure it matches the target noise frequency spectrum. Verify that the 700mOhm DC resistance does not cause excessive voltage drop in the signal path.

Part Context

This ferrite bead belongs to the BCAS series, which expands Max Echo's range of small ferrite chip EMI suppressors. The series utilizes advanced printing technology to achieve performance suitable for GHz frequencies within a miniature 0402 package, addressing the growing demand for compact noise control solutions.

Replacement Considerations

Check for direct substitutes with identical 220 Ohm impedance at 100 MHz and compatible 0402 dimensions. Ensure any replacement maintains the 200mA current handling capability and similar DC resistance characteristics to preserve circuit performance.
