Z0805C330ASMST

Overview

The KEMET Z0805C330ASMST is a multilayer ferrite chip bead designed for noise suppression in signal lines. It features a 0805 (2012 metric) surface-mount package with dimensions of 2 mm length, 1.25 mm width, and 0.85 mm height. The component provides an impedance of 33 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.2 A and has a maximum DC resistance of 50 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• Low DC resistance minimizes signal loss in power or signal paths
• Compact 0805 footprint suitable for space-constrained designs

Applications

• Signal line noise suppression
• High-speed data interface filtering
• General-purpose EMI suppression in consumer electronics

Procurement Notes

Verify the End-of-Life status before finalizing design specifications, as this part may be discontinued. Confirm RoHS compliance details through official manufacturer documentation. Ensure that the 1.2 A current rating meets the specific application requirements to prevent saturation or thermal issues during operation.

Selection Notes

Select this component when a 33 Ohm impedance at 100 MHz is required for noise control. The 0805 package size offers a balance between performance and board space. Consider the 25% impedance tolerance if precise filtering characteristics are not critical. Verify that the 1.2 A current handling capability aligns with the circuit's maximum operating current.
