1206J0250103MXTE01

Overview

The Knowles Syfer 1206J0250103MXTE01 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features a capacitance of 10 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a DC voltage of 25 VDC and supports a continuous current of 300 mA. It operates within a temperature range of -55°C to +125°C. The physical dimensions conform to the standard 1206 (3216 metric) package, ensuring compatibility with automated assembly processes.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency EMI suppression compared to standard two-terminal capacitors.
• Low inductance design inherent to the coaxial internal structure enhances performance in noise filtering applications.
• Capable of handling continuous currents up to 300 mA, suitable for power line filtering tasks.

Applications

• EMI/RFI filtering on data and power lines in electronic circuits
• Noise suppression in high-speed digital signal interfaces
• Power supply input/output filtering for sensitive components

Procurement Notes

Verify the specific suffix 'E01' indicates the three-terminal feed-through configuration with nickel barrier and 100% tin terminations. Confirm that the application requires the 300 mA current rating and 10 nF capacitance value. Ensure the PCB layout accommodates the distinct terminal arrangement required for feed-through mounting rather than standard parallel plate placement.

Selection Notes

Select this component when high-frequency noise attenuation is critical and space constraints limit the use of discrete filters. The X7R dielectric offers stable capacitance over the operating temperature range. Consider the 1206 footprint for board density. Evaluate if the 25 VDC rating meets the circuit's peak voltage requirements including transients.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically engineered for electromagnetic interference suppression. Unlike general-purpose capacitors, this series integrates shielding properties directly into the component body. It serves as a compact alternative to ferrite beads or LC filters in space-constrained designs requiring effective broadband noise reduction.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through form factor, 10 nF capacitance, 25 VDC rating, and 1206 package. Verify termination material compatibility if soldering conditions differ. Standard two-terminal 1206 capacitors are not functionally equivalent due to higher parasitic inductance.
