1812J2000473MJTE03

Overview

The Knowles Syfer 1812J2000473MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric. It offers a capacitance of 47 nF with a ±20% tolerance and a DC voltage rating of 200 V. The component utilizes a standard 1812 (4532 metric) package size, measuring 4.5 mm in length, 3.2 mm in width, and 2.5 mm in height. It operates within a temperature range of -55°C to +125°C and employs nickel barrier end terminations with 100% tin plating.

Feature Summary

• X2Y three-terminal architecture providing integrated common-mode noise suppression
• Nickel barrier termination system ensuring reliable solderability and mechanical stability
• High-temperature X7R ceramic dielectric for stable performance across wide thermal ranges

Applications

• Common-mode noise filtering in high-speed digital signal lines
• Power supply input/output decoupling in compact electronic modules
• EMI suppression circuits in automotive and industrial control systems

Procurement Notes

Verify the specific suffix 'JTE03' against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the 1812 footprint dimensions. Confirm RoHS compliance status through current datasheets before final integration.

Selection Notes

Select this component when space-constrained designs require combined decoupling and EMI filtering capabilities. The X2Y topology reduces the number of discrete components needed compared to traditional two-terminal capacitors. Evaluate the 200V rating against peak transient voltages in the target circuit to ensure adequate safety margins.

Part Context

This part belongs to the Knowles Syfer 1812J series of general-purpose MLCCs. The series is characterized by its robust construction and suitability for demanding environments. The 1812 case size allows for higher capacitance values while maintaining compatibility with standard SMT assembly processes used in modern electronics manufacturing.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 200V rating, 47nF capacitance, and X2Y three-terminal structure. Verify that alternative X2Y capacitors maintain similar self-resonant frequency characteristics and impedance profiles for equivalent noise suppression performance.
