NFZ32BW700HN10L

Overview

The NFZ32BW700HN10L is a single-line ferrite bead from the Murata EMIFIL NFZ32BW series, designed for surface-mount applications. It features a 1210 (3225 metric) package with dimensions of 3.2 mm length, 2.5 mm width, and 1.55 mm height. The component provides an impedance of 70 Ohms at 1 MHz with a tolerance of 30%. It supports a maximum DC current of 700 mA and has a maximum DC resistance of 380 mOhms. The operating temperature range spans from -40°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies.
• Utilizes a compact 1210 surface-mount footprint suitable for space-constrained circuit designs.
• Engineered for stable performance across a wide industrial temperature range.

Applications

• Noise filtering in portable electronic devices
• Signal integrity enhancement in data lines
• EMI suppression in consumer electronics

Procurement Notes

Verify the complete part number including suffixes to ensure correct impedance and packaging specifications. Confirm RoHS compliance status as required by project regulations. Check manufacturer datasheets for updated moisture sensitivity levels and recommended soldering profiles prior to assembly. Ensure storage conditions align with manufacturer guidelines to maintain component integrity.

Selection Notes

Select this component when a 70 Ohm impedance at 1 MHz is required for noise attenuation. The 700 mA current rating must accommodate the maximum continuous DC load of the target circuit. The 1210 package size should be compatible with the available PCB land pattern. Verify that the 380 mOhms DC resistance does not cause unacceptable voltage drop in the power or signal path.

Part Context

This component belongs to the Murata EMIFIL NFZ32BW series of ferrite beads. These components are specifically engineered for EMI suppression in digital circuits. The series offers various impedance values within the same 1210 package form factor, allowing designers to select appropriate filtering characteristics without altering the board layout.

Replacement Considerations

Compatible substitutes include other 1210 ferrite beads with similar 70 Ohm impedance and current ratings. Verify pin compatibility and thermal characteristics before substitution. Cross-reference with Murata's SimSurfing tool for detailed frequency response comparisons.
