SIM02121YA1033

Overview

The SIM02121YA1033 is a single-line ferrite bead manufactured by Meritek Electronics Corporation. It features a 0402 (1005 Metric) surface-mount package designed for high-frequency noise suppression applications. The component provides an impedance of 120 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum current rating of 100 mA and has a typical DC resistance of 0.30 Ohms. The physical dimensions are specified as 1.00 mm in length, 0.50 mm in width, and 0.30 mm in height.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Utilizes a compact 0402 surface-mount footprint for space-constrained circuit designs
• Constructed as a single-line component for efficient signal path filtering

Applications

• High-speed data line noise filtering
• Power supply decoupling in compact electronics
• RF circuit interference mitigation

Procurement Notes

Verify the exact impedance value and tolerance against the official Meritek datasheet Rev. 8c or later before integration. Confirm that the 100 mA current rating meets the operational requirements of the target circuit to prevent saturation. Ensure the 0402 package dimensions align with the PCB land pattern specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a low-profile ferrite bead is required for 100 MHz noise attenuation. The 120 Ohm impedance level suits moderate noise suppression needs without significant signal degradation for low-current signals. The 0402 size is appropriate for dense board layouts where larger packages cannot fit. Consider the 100 mA limit when designing power lines or high-current data paths.

Part Context

This part belongs to Meritek's general type chip ferrite bead series. It is distinct from multi-line or common-mode choke variants. The suffix YA1033 indicates specific impedance and packaging parameters within the SIM series. It serves as a passive component for EMI control rather than energy storage or active signal processing.

Replacement Considerations

Check for direct substitutes with identical 120 Ohm @ 100 MHz impedance and 0402 footprint. Verify current ratings and DC resistance values match to ensure equivalent performance. Consult Meritek documentation for approved alternative part numbers within the same series.
