Z0402C241ASMST

Overview

The KEMET Z0402C241ASMST is a ferrite chip bead from the Z-SMS series, designed for surface-mount applications in the 0402 (1005 metric) package. It provides an impedance of 240 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and features a maximum DC resistance of 250 mOhms. It operates within a temperature range of -55°C to +125°C and is classified as a commercial grade shielded device.

Feature Summary

• Provides high impedance attenuation for noise suppression in single-channel circuits
• Utilizes a compact 0402 surface-mount footprint for space-constrained designs
• Features shielded construction to minimize electromagnetic interference

Applications

• High-speed data line filtering
• Clock signal noise suppression
• Power supply output filtering

Procurement Notes

Verify end-of-life status and obsolescence notices directly with KEMET or authorized distributors before finalizing design-in decisions. Confirm RoHS compliance details and specific manufacturing lot dates upon order placement. Ensure that the commercial grade classification meets all environmental requirements for the intended deployment scenario.

Selection Notes

Select this component when a 240 Ohm impedance value is required at 100 MHz for noise control. Evaluate the 300 mA current rating against peak load conditions to prevent saturation. Consider the 0402 package dimensions for PCB layout constraints and compare thermal performance characteristics against alternative ferrite materials if operating near the upper temperature limit.

Part Context

This part belongs to the KEMET Z-SMS series of ferrite beads, which are engineered for general-purpose EMI suppression in consumer and industrial electronics. The series offers various impedance values within standard small-footprint packages to support diverse circuit protection needs.

Replacement Considerations

Consult official KEMET substitution guides for verified equivalents. Cross-reference impedance curves and current ratings carefully when evaluating alternative manufacturers.
