BLM03AG241SN1D

Chip Ferrite Bead Overview

The Murata BLM03AG241SN1D is a single-line chip ferrite bead in the BLM03_SN series, housed in a 0201 (0603 metric) surface-mount package. It provides an impedance of 240 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 200 mA and exhibits a maximum DC resistance of 800 mOhms. It operates within a temperature range of -55°C to +125°C and measures 0.6 mm in length, 0.3 mm in width, and 0.3 mm in height.

Chip Ferrite Bead Feature Summary

• Provides high-impedance attenuation for electromagnetic interference suppression in compact designs
• Supports operation across extended industrial temperature ranges
• Features low DC resistance to minimize power loss in signal lines

Chip Ferrite Bead Applications

• High-speed data line filtering
• Clock circuit noise suppression
• General-purpose EMI suppression in portable devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against the official Murata datasheet 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 the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Chip Ferrite Bead Selection Notes

Select this component when a 0201 footprint is required for space-constrained layouts. The 240 Ohm impedance at 100 MHz suits mid-frequency noise suppression. Verify that the 200 mA current rating exceeds the peak operating current of the protected circuit to prevent saturation or excessive heating during normal operation.

Chip Ferrite Bead Part Context

This component belongs to the Murata BLM03_SN series of chip ferrite beads. These parts are designed for general-purpose EMI suppression in electronic circuits. The series offers various impedance values within the standard 0201 package size, allowing designers to tailor noise filtering characteristics without altering the board footprint.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM03AG241 variants with compatible suffixes. Equivalent parts from other manufacturers must match the 0201 dimensions, 240 Ohm impedance at 100 MHz, and 200 mA current rating.
