NFZ15SG771SN10D

Overview

The NFZ15SG771SN10D is a single-line ferrite bead from the Murata EMIFIL NFZ series, designed for surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 770 Ohms at 900 MHz with a tolerance of ±25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 500 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-impedance noise suppression in a compact 0402 surface-mount footprint
• Engineered for exceptional solder heat resistance during manufacturing processes
• Operates reliably across a wide industrial temperature range from -55°C to +125°C

Applications

• High-speed data line filtering in portable electronic devices
• Noise suppression on power supply lines for integrated circuits
• EMI reduction in automotive infotainment and control systems

Procurement Notes

Verify the complete part number against official Murata documentation to ensure correct impedance and package specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any specific handling instructions related to the small form factor. Ensure the supplier provides valid traceability documents matching the manufacturer's batch codes.

Selection Notes

Select this component when space constraints require a 0402 package but higher current handling than smaller beads allows. The 500 mA rating suits moderate power distribution networks. Verify that the 770 Ohm impedance profile matches the target noise frequency spectrum. Consider thermal management implications given the small physical size and power dissipation characteristics under load.

Part Context

This component belongs to the Murata NFZ series of chip ferrite beads, specifically the SG variant optimized for general-purpose EMI suppression. The NFZ family is widely used in consumer electronics and automotive applications for its reliability and consistent performance. The 15 in the part number indicates the 0402 case size, distinguishing it from larger or smaller variants in the same product line.

Replacement Considerations

Direct substitutes include other Murata NFZ15SG series parts with similar impedance ratings, such as NFZ15SG601SN10D or NFZ15SG102SN10D, provided the impedance curve matches the application needs. Cross-brand replacements must match the 0402 footprint, 500 mA current rating, and 770 Ohm impedance at 900 MHz.
