Z0603C330APMST

Overview

The KEMET Z0603C330APMST is a surface-mount ferrite bead designed for EMI suppression in single-line applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.95 mm maximum height. The component provides an impedance of 33 ohms at 100 MHz and supports a rated current of 3 A. Its DC resistance is specified at 25 milliohms. The device operates within a temperature range of -55°C to +85°C and utilizes a ferrite material composition.

Feature Summary

• Provides effective electromagnetic interference filtering for high-speed signal lines
• Supports high continuous current loads up to 3 amperes
• Offers low DC resistance to minimize power loss in the circuit

Applications

• EMI suppression on USB data lines
• Noise filtering for clock signals in digital circuits
• Power line filtering in portable electronic devices

Procurement Notes

Verify the specific impedance tolerance and current rating against the official datasheet before integration. Confirm that the 0603 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a compact solution is needed for high-current EMI suppression. The 33-ohm impedance at 100 MHz makes it suitable for frequencies above typical audio ranges. Consider the low DC resistance for efficiency-critical power paths. Evaluate the thermal performance under continuous load conditions to ensure reliability.
