SIM03800Y3A032

Overview

The SIM03800Y3A032 is a surface-mount signal ferrite chip bead manufactured by Meritek Electronics Corporation. It features an impedance of 80 Ohms at 100 MHz with a tolerance of ±25%. The component supports a rated current of 3 Amperes and exhibits a maximum DC resistance of 40 milliohms. It is housed in a standard 0603 (1608 Metric) package designed for single-line applications. The device operates within a temperature range of -40°C to +125°C and complies with RoHS standards.

Feature Summary

• High current handling capability suitable for power line filtering
• Compact 0603 surface mount footprint for space-constrained designs
• Single-line configuration for efficient noise suppression

Applications

• DC-DC converter output filtering
• Power supply input noise attenuation
• High-speed digital signal line EMI suppression

Procurement Notes

Verify the specific suffix codes against the official Meritek datasheet to ensure exact impedance and current ratings match design requirements. Confirm RoHS compliance status through manufacturer documentation rather than distributor summaries. Check for lead-free specifications if required by assembly processes. Ensure the 0603 package dimensions align with PCB land pattern guidelines.

Selection Notes

Select this component when high current capacity is required alongside moderate impedance values. The 3A rating distinguishes it from lower-current general-purpose beads. Consider the 0603 size constraint for board real estate. Verify that the 80 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Evaluate thermal performance under continuous load conditions.

Part Context

This ferrite bead belongs to Meritek's signal ferrite chip bead series, specifically designed for high-current applications. The product line emphasizes low DC resistance to minimize voltage drop while maintaining effective electromagnetic interference suppression. It serves as a passive component for protecting sensitive circuits from high-frequency noise on power and data lines.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering 80 Ohms @ 100 MHz and ≥3A current ratings. Verify pin compatibility and impedance curves before substitution. Ensure equivalent thermal and mechanical characteristics are maintained in alternative sourcing decisions.
