BLF02GD162GNED

Chip Ferrite Bead Overview

The BLF02GD162GNED is a surface-mount ferrite bead from Murata’s BLF series, designed for EMI noise suppression in compact electronic circuits. It features an 01005 (0402 metric) package with dimensions of 0.4 mm length and 0.2 mm width. The component offers an impedance of 1600 ohms at its rated frequency and supports a maximum DC current of 100 mA. It exhibits a maximum DC resistance of 3 ohms and a tolerance of 40%. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Utilizes a miniature 01005 surface-mount package for space-constrained designs
• Supports standard SMD/SMT termination types for automated assembly

Chip Ferrite Bead Applications

• High-frequency signal line noise suppression
• Power supply circuit EMI filtering
• Portable electronic device internal noise control

Chip Ferrite Bead Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm package specifications and tape/reel configuration. Ensure that the selected variant matches the required impedance and current ratings for the target application. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when high attenuation is required in ultra-small form factors. Evaluate the impedance curve relative to the target noise frequency rather than relying solely on single-point ratings. Confirm that the 100 mA current limit aligns with the operational DC bias of the circuit to prevent performance degradation due to saturation effects.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLF series of passive ferrite beads, which are engineered for noise suppression in digital and RF circuits. The series provides various impedance values and current ratings across multiple package sizes, allowing designers to balance filtering performance with physical space constraints in modern consumer electronics.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 01005 footprint, 1600 ohm impedance, and 100 mA current rating. Verify thermal stability and DC resistance equivalence to ensure identical noise suppression characteristics without altering the PCB layout or electrical performance.
