EBMS201209B272

Overview

The EBMS201209B272 is a multilayer ferrite chip bead from the Max Echo EBMS series, designed for EMI suppression in signal lines. It features a 0805 (2012 Metric) surface-mount package with dimensions of 2.00mm x 1.25mm and a maximum height of 0.035 inches (0.90mm). The component provides an impedance of 2.7 kOhms at 100 MHz and supports a rated current of 200mA. Its maximum DC resistance is 600mOhm. It operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• Compact 0805 footprint suitable for space-constrained PCB layouts
• Single-line configuration for targeted signal path filtering

Applications

• High-speed digital signal line filtering
• Power supply noise suppression in compact electronics
• EMI reduction in mobile device circuitry

Procurement Notes

Verify the specific ordering suffix and packaging type (TR, CT, or Digi-Reel) against the distributor's current listing to ensure compatibility with automated assembly equipment. Confirm that the manufacturer part number matches exactly, as variations in suffixes may indicate different tape-and-reel specifications or minor parameter tolerances not explicitly detailed in general summaries.

Selection Notes

Select this component when a 2.7 kOhm impedance at 100 MHz is required for a single signal line carrying up to 200mA. Ensure the PCB land pattern accommodates the 0805 (2012 Metric) package dimensions. Verify that the operating environment stays within the specified -55°C to +125°C range and that the low DC resistance of 600mOhm meets the voltage drop requirements of the circuit design.

Part Context

This ferrite bead belongs to the EBMS series by Max Echo Technology Corp., which specializes in multilayer chip inductors and EMI suppressors. The series is engineered for applications handling currents under 3A, offering a balance of high impedance performance and compact physical size for modern electronic designs requiring efficient noise control.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the MMZ1608B272CTAH0 from TDK. When replacing, verify that the substitute maintains the same 2.7 kOhm impedance at 100 MHz, 200mA current rating, and 0805 package dimensions to ensure mechanical and electrical compatibility.
