1812Y2000274MXTE07

Overview

The Knowles Syfer 1812Y2000274MXTE07 is a feed-through capacitor designed for surface-mount applications. It features a capacitance of 0.27 µF and a voltage rating of 200 VDC. The component utilizes an X7R dielectric material, ensuring stability across its operating temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it supports a continuous current of 2 A. This device integrates filtering capabilities directly into the mounting footprint, offering a compact solution for high-frequency noise suppression in dense circuit layouts.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Supports continuous current handling up to 2 A for power line applications
• Utilizes X7R ceramic dielectric for stable capacitance performance over temperature variations

Applications

• High-frequency noise suppression on DC power lines
• EMI/RFI filtering in compact electronic assemblies
• Signal integrity protection in high-density PCB designs

Procurement Notes

Verify the complete part number including the suffix E07 against official manufacturer documentation to confirm specific termination or packaging variants. Ensure compatibility with surface-mount reflow processes. Confirm RoHS compliance status through the latest datasheet before integration. Cross-reference electrical ratings with system requirements to validate voltage and current margins under all operating conditions.

Selection Notes

Select this component when space constraints preclude discrete filter components. The integrated feed-through design reduces board area compared to traditional LC filters. Verify that the 2 A current rating exceeds maximum expected load currents. Consider the X7R temperature coefficient if capacitance stability is critical across wide thermal ranges. Ensure the 1812 package dimensions fit within the designated land pattern.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which combines passive filtering with mechanical mounting. Unlike standard MLCCs, these devices provide inherent low-inductance paths for noise dissipation. The 1812 form factor allows for automated placement while maintaining robust electrical performance in demanding environments.
