SZ1608G121CTF

Overview

The SZ1608G121CTF is a multi-layer chip ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It belongs to the SZ series and utilizes a 0603 (1608 metric) surface-mount package with dimensions of 1.60 x 0.80 mm and a height of 0.80 mm. The component provides an impedance of 120 Ohms at 100 MHz with a tolerance of ±25%. It features a maximum DC resistance of 300 mOhm and supports a rated current of 700 mA. The device operates within a temperature range of -55°C to +125°C and is designed for consumer electronics applications.

Feature Summary

• Multi-layer construction for compact surface-mount integration
• High impedance performance at 100 MHz for signal line filtering
• Robust thermal stability across extended operating temperatures

Applications

• Consumer electronics signal lines
• Data line noise suppression
• Power supply filtering in portable devices

Procurement Notes

Verify the part number SZ1608G121CTF against official Sunlord documentation to confirm specifications. Ensure the supplier provides evidence of authenticity, as counterfeit components may exhibit incorrect impedance or current ratings. Check for RoHS compliance markings if required by your manufacturing standards. Confirm the package type matches the 0603 footprint requirements of your PCB design.

Selection Notes

Select this component when a low-profile 0603 ferrite bead is required for high-frequency noise attenuation on signal lines. The 120 Ohm impedance at 100 MHz makes it suitable for digital data interfaces. Consider the 700 mA current rating to ensure adequate headroom for the application's operational current. Verify that the 300 mOhm DC resistance meets the voltage drop constraints of the circuit.
