Overview
The NFZ32BW621HZ10L is a surface-mount ferrite bead from the Murata EMIFIL NFZ series, housed in a 1210 (3225 metric) package. It provides an impedance of 620 Ohms with a tolerance of 30% and supports a maximum DC current of 250 mA. The component features a maximum DC resistance of 2.7 Ohms and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 3.2 mm in length, 2.5 mm in width, and 1.55 mm in height.
Feature Summary
- Designed for radiation noise suppression in the 30 to 150 MHz frequency range
- Delivers high impedance characteristics within a compact surface-mount footprint
Applications
- Radiation noise filtering for electronic circuits
- High-frequency signal line protection
- EMI suppression in compact device designs
Procurement Notes
Verify the specific suffix against official Murata documentation to confirm exact impedance and tolerance specifications. Ensure the selected packaging format aligns with automated assembly requirements. Confirm RoHS compliance status through the manufacturer's latest product declaration before integration into regulated products.
Selection Notes
Select this component when circuit design requires significant attenuation of high-frequency radiation noise between 30 and 150 MHz. The 1210 package size offers a balance between current handling capability and board space efficiency. Verify that the 250 mA current rating meets the operational load of the target signal line without causing excessive voltage drop.
Part Context
This part belongs to the Murata NFZ series of chip noise filters, which are engineered specifically for suppressing electromagnetic interference in high-frequency applications. The series utilizes specialized ferrite materials to achieve high impedance values in small packages, making it suitable for modern dense PCB layouts requiring effective EMI control.
FAQ
What is the primary frequency range for noise suppression?
The NFZ series is designed for radiation noise ranges from 30 to 150 MHz.
Does the impedance value change with frequency?
Yes, the specified 620 Ohms is the impedance value at the test frequency; impedance varies across the spectrum.
