1812Y2000393MXTE03

Overview

The Knowles Syfer 1812Y2000393MXTE03 is a feed-through multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 0.039 µF with a voltage rating of 200 VDC and a current handling capacity of 50 mA. The component utilizes X7R dielectric material, providing stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it offers a compact footprint suitable for high-density circuit board layouts.

Feature Summary

• Integrated pass-through architecture enables direct signal path integration within the component structure.
• X7R dielectric composition ensures reliable capacitance stability under varying thermal conditions.
• Surface mount construction facilitates automated assembly and secure PCB attachment.

Applications

• High-frequency signal filtering in communication equipment
• Power supply noise suppression in industrial electronics
• EMI/RFI mitigation in automotive control modules

Procurement Notes

Verify specific packaging configurations such as reel or cut tape availability directly with authorized distributors. Confirm RoHS compliance status and environmental declarations against current regulatory requirements before finalizing procurement orders. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain component integrity during handling and soldering processes.

Selection Notes

Select this component when a compact feed-through solution is required for 200V DC applications. The 1812 package size balances current handling capabilities with space constraints. Consider the X7R temperature coefficient for environments with moderate thermal fluctuations. Evaluate the 50 mA current rating against peak load requirements to ensure adequate performance margins.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in feed-through capacitors. These components integrate filtering functions directly into the mounting structure, reducing parasitic inductance compared to traditional discrete capacitors. The series is engineered for high-reliability applications requiring robust electromagnetic interference suppression in confined spaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications carefully if considering alternative manufacturers. Consult official manufacturer databases for cross-reference lists to ensure functional equivalence without redesigning the circuit layout.
