SZ1608K221TF

Overview

SZ1608K221TF is a multi-layer chip ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. This component belongs to the passive electronic components category, specifically designed for noise suppression applications in high-frequency circuits. The part features a 0603 (1608 metric) surface-mount package, ensuring compatibility with standard PCB footprints. It provides an impedance of 220 ohms at 100 MHz with a tolerance of ±25%. The device is rated for a single line configuration and complies with RoHS standards, making it suitable for environmentally conscious manufacturing processes.

Feature Summary

• Provides effective electromagnetic interference (EMI) suppression through high impedance characteristics at target frequencies.
• Utilizes a compact 0603 surface-mount package design for space-constrained circuit board layouts.
• Constructed using multi-layer ceramic technology to ensure mechanical stability and consistent electrical performance.
• Complies with RoHS directives for restricted hazardous substances in electronic equipment.

Applications

• Noise filtering in high-speed digital signal lines
• Power supply input/output decoupling circuits
• RF circuit impedance matching and isolation

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against your circuit design before ordering. Confirm that the 0603 package dimensions align with your PCB footprint specifications. Ensure compliance with RoHS regulations if required by your end-product standards. Cross-reference the manufacturer's latest datasheet for any revisions to the electrical characteristics or recommended soldering profiles to guarantee reliable assembly and long-term operational stability.

Selection Notes

Select this component when a 220-ohm impedance at 100 MHz is required for noise attenuation in compact designs. Consider the ±25% tolerance for budgeting impedance variations in sensitive RF paths. Evaluate the DC resistance and maximum current handling capabilities to prevent saturation or excessive voltage drop in power lines. Compare alternative packages if space allows, but prioritize this form factor for dense layouts requiring standard 0603 mounting.

Part Context

Shenzhen Sunlord Electronics Co., Ltd. specializes in the development and manufacturing of passive electronic components, including magnetic devices and microwave components. The SZ series represents their range of multi-layer chip ferrite beads designed for EMI suppression.
