NFZ5BBW6R7LZ10L

Overview

The Murata NFZ5BBW6R7LZ10L is a single-channel chip noise filter from the EMIFIL NFZ series. It features a 2020 (5050 metric) surface-mount package with dimensions of 5.0 mm length, 5.0 mm width, and 2.2 mm maximum height. The component provides an impedance of 6.7 Ohms at a test frequency of 1 MHz. It supports a maximum DC current of 3.1 A and has a maximum DC resistance of 23 mOhms. The device operates within a temperature range of -40°C to +125°C and meets RoHS3 standards.

Feature Summary

• Provides EMI suppression through ferrite bead technology in a compact surface-mount form factor.
• Engineered for high current handling capabilities suitable for power line applications.
• Designed with excellent solder heat resistance for reliable reflow processing.

Applications

• Power supply input filtering
• DC-DC converter output noise reduction
• General EMI suppression in electronic circuits

Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm impedance values and tolerance levels. Ensure that the selected variant matches the required DC current rating and physical footprint for the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when a low-profile 2020 package is required for high-current noise filtering applications. Evaluate the 6.7 Ohm impedance characteristic against the target noise spectrum to ensure effective attenuation. Confirm that the 3.1 A current rating exceeds the maximum operating current of the circuit to prevent saturation or excessive heating during normal operation.

Part Context

This component belongs to the Murata NFZ5BBW series of chip noise filters. The series is characterized by its small 2020 package size and robust construction for automotive and industrial environments. It serves as a passive electromagnetic interference suppression device, distinct from active filtering solutions or other capacitor-based EMI mitigation components.

Replacement Considerations

Direct substitutes include other NFZ5BBW variants with similar impedance and current ratings, such as NFZ5BBW7R6LN10L or NFZ5BBW100LZ10L, provided the impedance specifications align with the design requirements. Verify pin compatibility and thermal characteristics before substitution.
