Overview
The KEMET Z0402C680APMST is a single-channel ferrite chip bead from the Z-PMS series, designed for EMI suppression in power line applications. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 68 ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 75 mΩ. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides effective electromagnetic interference suppression for power lines
- Designed for high-current applications with a 1.5 A rating
- Utilizes a compact 0402 surface-mount footprint for space-constrained designs
Applications
- Power line noise suppression
- EMI filtering in electronic circuits
- Signal integrity enhancement in compact devices
Procurement Notes
Verify the specific suffix 'A' against official KEMET documentation to confirm exact electrical characteristics and packaging details. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm end-of-life status or availability through authorized distributors prior to finalizing procurement plans.
Selection Notes
Select this component when a low-profile 0402 ferrite bead is required for power lines carrying up to 1.5 A. The 68-ohm impedance at 100 MHz targets specific frequency ranges for noise attenuation. Compare the 75 mΩ DCR against circuit voltage drop constraints. Consider the Z-PMS series characteristics for automotive or industrial reliability if applicable.
Part Context
This part belongs to the KEMET Z-PMS series of ferrite beads, which are engineered for power line applications. The series offers various impedance values and current ratings in standard SMD packages. The Z0402C680APMST specifically addresses the need for compact, high-current noise suppression in modern electronics.
Replacement Considerations
Consult KEMET datasheets for direct substitutes within the Z-PMS series with matching 68-ohm impedance and 1.5 A current rating. Verify that alternative components maintain the same 0402 footprint and thermal performance specifications.
