1206J0250124MJTE07

Overview

The Knowles Syfer 1206J0250124MJTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a 120 nF capacitance with a ±20% tolerance, rated at 25 VDC using X7R dielectric material. The component utilizes a 1206 (3216 metric) package size and incorporates a nickel barrier with 100% tin terminations. As an EMI filter, it provides high-frequency noise suppression capabilities.

Feature Summary

• Three-terminal architecture functions as an integrated EMI filter for signal integrity
• Nickel barrier termination system ensures reliable solderability and corrosion resistance
• X7R dielectric composition supports stable performance across standard operating temperatures

Applications

• High-frequency noise suppression in electronic circuits
• EMI filtering for sensitive signal lines
• Surface mount assembly requiring compact filter solutions

Procurement Notes

Verify the specific suffix configuration to confirm the presence of the nickel barrier and three-terminal structure. Ensure compatibility with the target PCB footprint for 1206 EMI filter components. Confirm that the X7R dielectric characteristics meet the thermal requirements of the intended application environment before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require integrated filtering without additional discrete inductors. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Verify that the 25 VDC rating aligns with the circuit's maximum voltage peaks to ensure long-term reliability under operational stress.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically engineered for electromagnetic interference mitigation. Unlike standard capacitors, the three-terminal construction allows for lower effective series inductance, making it suitable for high-speed digital and RF applications where noise isolation is critical for system stability.

Replacement Considerations

Direct substitutes must match the 1206 package, 120 nF value, and three-terminal EMI filter topology. Verify terminal plating specifications and dielectric type to maintain equivalent filtering performance and mechanical fit.
