NFZ32BW9R0HN10L

Overview

The Murata Electronics NFZ32BW9R0HN10L is a surface-mount ferrite bead from the EMIFIL NFZ series, designed for EMI suppression. 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 9 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 device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides attenuation of common mode noise specifically for power lines in LED lighting equipment
• Utilizes a compact 1210 surface-mount footprint for efficient PCB integration
• Constructed as a single-line ferrite bead for targeted signal path filtering

Applications

• EMI suppression in LED lighting equipment power lines
• Common mode noise attenuation in electronic circuits
• High-frequency noise filtering in portable devices

Procurement Notes

Verify the specific impedance value against the official datasheet, as distributor listings may contain conflicting data regarding 9 Ohms versus other values. Confirm the maximum DC current rating matches design requirements, noting discrepancies between 700 mA and higher ratings found in similar family members. Ensure the package dimensions align with the target footprint before finalizing procurement orders.

Selection Notes

Select this component when a 1210 form factor is required for space-constrained designs. The 9 Ohm impedance at 1 MHz suits applications targeting specific high-frequency noise bands. Evaluate the 700 mA current limit to ensure it accommodates the circuit's peak DC load without saturation. Consider the -40°C to +125°C operating range for environmental compatibility.
