1812Y2000272MXTE03

Overview

The Knowles Syfer 1812Y2000272MXTE03 is a feed-through multilayer ceramic capacitor designed for high-frequency noise suppression. It features a capacitance of 2700 pF with a voltage rating of 200 VDC and a tolerance of 20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) surface-mount package, it includes a 50 mA fuse element integrated into the structure for overcurrent protection.

Feature Summary

• Integrates a built-in fuse element providing simultaneous capacitive filtering and circuit protection against overcurrent conditions.
• Utilizes a three-terminal feed-through architecture to minimize parasitic inductance and enhance high-frequency noise attenuation performance.

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering where combined decoupling and protection are required
• Signal integrity enhancement in RF and high-speed digital applications

Procurement Notes

Verify the specific suffix 'JTE03' against official manufacturer documentation to confirm the exact terminal configuration and fuse current rating. Ensure the selected variant matches the required 200V DC rating and 2700 pF capacitance for the target application. Cross-reference the datasheet for precise footprint dimensions and reflow soldering profiles to guarantee reliable assembly.

Selection Notes

Select this component when a single device must provide both EMI filtering and overcurrent protection. The 1812 package offers a compact form factor suitable for space-constrained designs. Consider the 50 mA fuse limit during selection to ensure it aligns with the maximum operating current of the protected circuit without nuisance tripping.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines MLCC technology with fuse functionality. These components are engineered to replace traditional discrete filter and fuse combinations, simplifying board layout and reducing overall system volume while maintaining robust electrical performance.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative feed-through capacitors by matching the 2700 pF capacitance, 200 VDC rating, 50 mA fuse rating, and 1812 package dimensions.
