SZ1005K421TF

Overview

The SZ1005K421TF is a single-line multilayer chip ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm length, 0.50mm width, and a maximum height of 0.65mm. The component provides an impedance of 420 Ohms at 100 MHz with a tolerance of ±25%. It supports a rated current of 100mA and exhibits a maximum DC resistance of 1 Ohm. The device operates within a temperature range of -55°C to +125°C and holds a Moisture Sensitivity Level of 1.

Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz
• Utilizes a compact 0402 surface-mount footprint for dense circuit board layouts
• Constructed as a multilayer ceramic structure for robust signal line filtering

Applications

• Signal line filtering in consumer electronics
• Noise suppression in communication equipment
• EMI reduction in computer hardware

Procurement Notes

Verify the manufacturer part number SZ1005K421TF against official Sunlord documentation to confirm specifications. Ensure the received components match the 0402 package size and electrical ratings. Check for authenticity through authorized distribution channels. Confirm compliance with RoHS3 standards if required by the design specification.

Selection Notes

Select this component when a 420 Ohm impedance at 100 MHz is required for signal integrity. The 100mA current rating limits suitability for power lines; it is intended for low-current signal paths. The 0402 package dictates board space constraints. Verify that the 1 Ohm DC resistance meets the voltage drop requirements of the specific circuit application.

Part Context

This ferrite bead belongs to the general-purpose multilayer chip series from Sunlord. It is designed for EMI suppression in digital circuits. The component is classified under passive electronic filters. It is distinct from inductors or capacitors due to its resistive-inductive behavior at high frequencies.
