• Utilizes a nickel barrier structure on external electrodes to ensure excellent solderability and thermal resistance.
• Functions as a resistive element at noise frequencies to minimize signal waveform distortion.
• Designed for use in circuits with unstable ground connections without requiring a ground connection.

Applications

• Suppression of electromagnetic interference in general-purpose electronic circuits
• Noise filtering on continuous voltage lines in portable devices
• EMI control in systems with unstable grounding configurations

Procurement Notes

Verify the suffix HZ against HN variants, as they may indicate differences in packaging or tape specifications rather than electrical performance. Confirm the component status, as some related models in this series are marked as not recommended for new designs. Ensure compatibility with standard 1210 footprints and validate that the 1.2 A current rating meets the specific circuit requirements before finalizing procurement.

Selection Notes

Select this component when a 31 Ohm impedance at 1 MHz is required for EMI filtering in space-constrained designs. The 1210 package offers a balance between current handling capability and board area efficiency. Consider the 1.2 A rated current and low DC resistance for power line applications where minimal voltage drop is critical. Ensure the operating temperature range of -40°C to +125°C aligns with the environmental conditions of the target application.
