1812J2000272MJTE03

Overview

The Knowles Syfer 1812J2000272MJTE03 is a feed-through multilayer ceramic capacitor designed for surface-mount applications. It features a capacitance of 2700 pF and a voltage rating of 200 VDC, with a maximum current handling capacity of 50 mA. 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 provides a compact footprint suitable for high-density circuit board layouts.

Feature Summary

• Integrates feed-through architecture to provide effective electromagnetic interference suppression directly on the conductor path.
• Supports continuous DC current loads up to 50 mA without performance degradation.
• Utilizes X7R dielectric characteristics to maintain stable capacitance across wide operating temperature variations.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise suppression in industrial control systems
• Electromagnetic compatibility enhancement in automotive electronic modules

Procurement Notes

Verify the specific terminal configuration and pinout against the official datasheet before integration, as feed-through components require distinct PCB pad geometries compared to standard capacitors. Confirm that the 50 mA current rating aligns with the operational requirements of the target circuit to prevent thermal issues or component failure during sustained operation.

Selection Notes

Select this component when both signal integrity filtering and power line conditioning are required within a single surface-mount device. The 1812 package offers a balance between physical size and electrical performance. Ensure the design accommodates the specific mounting orientation required for feed-through functionality, distinguishing it from conventional parallel-plate MLCCs.

Part Context

This part belongs to the Knowles Syfer XT series of high-reliability ceramic capacitors. Unlike standard MLCCs, this specific model incorporates a feed-through structure, allowing it to function as both a filter and a conductive path. It is engineered for environments demanding robust electromagnetic interference mitigation alongside reliable electrical connectivity.

Replacement Considerations

Direct substitutes must match the 2700 pF capacitance, 200 V rating, 50 mA current capability, and 1812 feed-through form factor. Generic MLCCs cannot replace this component due to the absence of the internal conductive feed-through structure.
