1206J0250822MXTE01

Overview

The Knowles Syfer 1206J0250822MXTE01 is a three-terminal multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric with a capacitance of 8.2 nF and a tolerance of ±20%. The component is rated for a DC voltage of 25 VDC and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it utilizes a nickel barrier electrode structure with 100% tin terminations. This configuration provides enhanced electromagnetic interference (EMI) filtering capabilities compared to standard two-terminal devices.

Feature Summary

• Three-terminal architecture providing superior high-frequency noise suppression and EMI filtering performance
• Nickel barrier internal electrode construction ensuring robust reliability under thermal stress
• X7R dielectric material offering stable capacitance characteristics across the specified operating temperature range

Applications

• High-speed digital circuit power distribution networks requiring decoupling
• RF signal lines necessitating low-inductance noise attenuation
• Automotive electronic modules subject to strict electromagnetic compatibility standards

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm the three-terminal EMI filter variant. Ensure that the procurement specifications explicitly require the nickel barrier termination system, as this distinguishes the component from standard MLCCs. Cross-reference the part number with current datasheets to validate availability status and manufacturing origin details prior to ordering.

Selection Notes

Select this component when circuit design requires integrated EMI filtering alongside bulk capacitance in a compact footprint. The three-terminal design reduces effective series inductance, making it suitable for frequencies where standard capacitors exhibit degraded performance. Confirm that the PCB layout supports the distinct terminal arrangement required for proper grounding and signal path isolation.

Part Context

This component belongs to the Knowles Syfer general-purpose and high-reliability MLCC portfolio. It represents a specialized evolution of standard 1206 capacitors, integrating shielding structures directly into the passive element. The product line targets applications demanding high stability and noise immunity without increasing board space consumption.

Replacement Considerations

Direct substitution requires matching the three-terminal physical footprint and electrical ratings. Verify that alternative components offer comparable nickel barrier construction if environmental robustness is critical. Standard two-terminal replacements will not provide equivalent high-frequency noise attenuation characteristics.
