EBMS201209K252

Overview

The Max Echo EBMS201209K252 is a multilayer ferrite chip bead designed for signal line EMI suppression. It features an 0805 (2012 Metric) surface-mount package with dimensions of 0.079" length and 0.049" width. The component provides an impedance of 2.5 kOhms at 100 MHz, supporting a maximum current rating of 200mA. Its DC resistance is limited to a maximum of 700mOhm. The device 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 surface-mount footprint for space-constrained layouts
• High impedance characteristic optimized for single signal lines

Applications

• Signal line filtering in portable electronic devices
• EMI suppression on data transmission interfaces
• Noise reduction in consumer electronics power circuits

Procurement Notes

Verify the specific ordering suffix to ensure the correct impedance value and packaging configuration match the design requirements. Confirm that the supplier provides official datasheets and compliance certificates such as RoHS3. Check lead times and minimum order quantities directly with authorized distributors to align with production schedules. Ensure storage conditions respect the moisture sensitivity level specified in the manufacturer documentation.

Selection Notes

Select this component when a high impedance value of 2.5 kOhms is required at 100 MHz for signal integrity. The 200mA current rating suits low-power signal applications rather than high-current power lines. The 0805 package offers a balance between performance and board space. Consider the 700mOhm DC resistance impact on signal loss if the application is sensitive to insertion loss.

Part Context

This part belongs to the EBMS series of multilayer ferrite chips manufactured by Max Echo Technology Corp. The series utilizes proprietary ceramic materials to achieve stable electromagnetic interference suppression characteristics across a wide frequency range. The EBMS201209K252 specifically targets applications requiring significant attenuation of high-frequency noise in compact form factors.

Replacement Considerations
