1812J2000562MXTE03

Overview

The Knowles Syfer 1812J2000562MXTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 5600 pF with a voltage rating of 200 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it integrates a built-in resistor element rated at 50 mA to provide damping characteristics. This configuration supports effective electromagnetic interference filtering in compact circuit layouts.

Feature Summary

• Integrates a feed-through architecture combining capacitive coupling with resistive damping for enhanced signal integrity
• Provides effective high-frequency noise suppression through specialized internal structure
• Designed for surface-mount assembly to facilitate automated manufacturing processes

Applications

• High-speed digital signal line filtering
• Power supply input/output noise reduction
• Electromagnetic interference suppression in communication equipment

Procurement Notes

Verify the specific suffix MXTE03 against official datasheets to confirm the integrated resistor value and terminal configuration. Ensure compatibility with PCB pad designs intended for feed-through components rather than standard MLCCs. Confirm RoHS compliance status and moisture sensitivity level prior to procurement planning.

Selection Notes

Select this component when simultaneous capacitance and damping are required to prevent ringing on transmission lines. Evaluate the 50 mA current rating against operational load requirements. Consider the 200 VDC rating relative to peak voltage transients in the target application environment.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors due to its internal resistive element. It addresses scenarios where pure capacitance may cause signal reflections or oscillations. The 1812 form factor allows integration into space-constrained boards requiring robust EMI performance.

Replacement Considerations

Direct substitutes must match the 5600 pF capacitance, 200 VDC rating, and specifically the integrated 50 mA resistive damping characteristic. Standard MLCC replacements will not provide equivalent signal damping and may alter circuit stability.
