Overview
The SZ1005K121TF is a surface-mount ferrite bead manufactured by Shenzhen Sunlord Electronics Co., Ltd. It belongs to the SZ series and utilizes a 0402 (1005 metric) package with dimensions of 1.00 x 0.50 mm. The component provides an impedance of 120Ω at 100MHz with a tolerance of ±25%. It supports a rated current of 400mA and exhibits a maximum DC resistance of 400mΩ. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Utilizes a multilayer chip ceramic structure with internal silver electrodes for reliable performance.
- Provides high attenuation in specific frequency ranges due to sharp impedance rise while maintaining signal integrity.
- Features ferrite shielding to prevent crosstalk between adjacent components.
Applications
- Consumer electronics circuits
- High-frequency noise suppression
- Signal line filtering
Procurement Notes
Verify the part number against official Sunlord documentation to confirm the specific suffix 'K' characteristics, including the 400mA rating and 400mΩ DCR. Ensure the procurement channel sources genuine components from Shenzhen Sunlord Electronics Co., Ltd. to guarantee compliance with the specified electrical parameters and operating temperature range.
Selection Notes
Select this component when a compact 0402 footprint is required for noise suppression in consumer applications. The 120Ω impedance at 100MHz targets specific interference frequencies. Verify that the circuit's operating current does not exceed the 400mA limit and that the thermal environment remains within the -55°C to +125°C specification.
