1812J5000102MCTE03

Overview

The Knowles Syfer 1812J5000102MCTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 1000 pF with a DC voltage rating of 500 VDC and a current rating of 50 mA. The component utilizes a 1812 (4532 metric) package outline, measuring 4.5 mm in length, 3.2 mm in width, and 2.5 mm in height. It employs a three-pad configuration to facilitate high-frequency noise suppression.

Feature Summary

• Integrates feed-through architecture for effective electromagnetic interference filtering within compact surface-mount layouts.

Applications

• High-frequency noise suppression in electronic circuits
• Power supply input/output filtering applications
• Signal integrity enhancement in sensitive RF environments

Procurement Notes

Verify the specific three-pad footprint requirements against your PCB design, as this differs from standard two-terminal MLCCs. Confirm that the 50 mA current rating meets your circuit's operational demands. Ensure compatibility with reflow soldering profiles suitable for high-voltage ceramic components. Cross-reference the exact datasheet revision to confirm mechanical dimensions and terminal plating specifications before finalizing procurement.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete inductors or capacitors. The 1812 package provides a balance between capacitance density and physical robustness. Consider the 500 VDC rating for applications requiring isolation or handling higher potential differences. Evaluate the thermal management capabilities of the surrounding circuitry due to the power dissipation characteristics inherent in feed-through designs.

Part Context

This part belongs to the Knowles Syfer portfolio of high-reliability ceramic capacitors. It represents a specialized category of feed-through devices distinct from standard parallel-plate MLCCs. These components are engineered to provide superior high-frequency performance by minimizing parasitic inductance through their unique internal structure and external pad arrangement.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Replacement requires matching the 1812 footprint, 500 VDC rating, 1000 pF capacitance, and specifically the three-pad feed-through terminal configuration.
