1206Y2000682MSTE03

Overview

The Knowles Syfer 1206Y2000682MSTE03 is a three-terminal feed-through capacitor housed in a 1206 (3216 metric) surface-mount package. It features a capacitance of 6800 pF with a DC voltage rating of 200V and a current rating of 50 mA. The component utilizes an X7R dielectric material and includes a nickel barrier structure. Designed for high-reliability applications, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal feed-through architecture providing superior electromagnetic interference filtering compared to standard two-terminal capacitors
• Nickel barrier construction integrated into the termination design to enhance solderability and mechanical robustness
• X2Y topology configuration that offers common-mode and differential-mode noise suppression within a single compact footprint

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive digital circuits
• Electromagnetic interference suppression in automotive electronic control units

Procurement Notes

Verify the specific suffix MSTE03 against the manufacturer's latest datasheet to confirm the presence of the nickel barrier and exact terminal configuration. Ensure the selected distributor provides traceable documentation matching the original Knowles Syfer manufacturing records. Confirm that the three-terminal pad layout on the target printed circuit board aligns with the physical dimensions specified in the official mechanical drawing.

Selection Notes

Select this component when space-constrained designs require effective noise attenuation without increasing the board area. The three-terminal design is preferred over standard MLCCs for applications demanding higher isolation between input and output grounds. Consider the 50 mA current rating to ensure the component can handle the expected ripple currents without degradation. Verify compatibility with the assembly process regarding the specific termination metallurgy.

Part Context

This part belongs to the Knowles Syfer X2Y family, which integrates four electrodes into a single chip to function as both a common-mode and differential-mode filter. The 1206Y series denotes the standard 1206 case size. The MSTE03 suffix typically indicates specific termination materials and packaging details defined by the manufacturer for this particular variant.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through form factor and X2Y functionality. Standard two-terminal capacitors cannot replicate the noise suppression characteristics. Verify equivalent capacitance, voltage rating, and physical footprint before substitution.
