NFZ5BBW2R9LN10L

Overview

The Murata Electronics NFZ5BBW2R9LN10L is a single-channel chip noise filter from the EMIFIL NFZ series, designed for surface-mount technology. It features a 2020 (5050 metric) package with dimensions of 5.0 mm length, 5.0 mm width, and 2.0 mm height. The component exhibits an impedance of 2.9 Ohms at a test frequency of 1 MHz with a tolerance of ±30%. It supports a maximum DC current of 4 A and has a maximum DC resistance of 12 mOhms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics in the radio frequency range.
• Utilizes a compact 2020 surface-mount footprint suitable for space-constrained printed circuit board layouts.
• Engineered to handle high direct current loads while maintaining low insertion loss in the DC path.

Applications

• Noise filtering in audio line circuits
• EMI suppression for portable electronic devices
• Signal integrity management in consumer electronics

Procurement Notes

Verify the specific ordering suffix against official Murata documentation to ensure correct impedance and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when a 2020 package size is required for high-current applications up to 4 A. Ensure the 2.9 Ohm impedance at 1 MHz aligns with the target noise spectrum. Verify that the operating temperature range meets the environmental conditions of the final assembly. Consider the physical dimensions for clearance and soldering pad design compatibility.
