1812Y0500272MJTE03

Overview

The Knowles Syfer 1812Y0500272MJTE03 is a surface-mount feed-through capacitor with a capacitance of 2700 pF and a voltage rating of 50 VDC. It utilizes X7R dielectric material with a ±20% tolerance. The component operates within a temperature range of -55°C to +125°C and features a 1812 (4532 metric) package size. Designed for high-frequency applications, it provides effective electromagnetic interference suppression through its integrated feed-through architecture.

Feature Summary

• Integrated feed-through structure for direct signal line integration
• X7R dielectric material for stable performance across operating temperatures
• Surface-mount design compatible with automated assembly processes

Applications

• High-frequency signal filtering in communication equipment
• Electromagnetic interference suppression in sensitive electronic circuits
• Power supply noise reduction in compact devices

Procurement Notes

Verify the complete part number including suffixes to ensure correct dielectric type and termination specifications. Confirm feed-through current ratings against application requirements. Check manufacturer documentation for specific handling instructions related to ceramic components. Ensure compatibility with PCB layout constraints for feed-through mounting styles.

Selection Notes

Select this component when low-profile EMI filtering is required on signal lines. The 1812 package offers a balance between capacitance value and board space. Consider the X7R temperature characteristics for environments with moderate thermal variations. Evaluate the 50 mA current rating to ensure it meets the operational load without degradation.

Part Context

This component belongs to the Knowles Syfer 1812Y series of feed-through capacitors. These parts are designed to replace traditional discrete filter components by integrating capacitance directly into the signal path. The series supports various capacitance values and voltage ratings within the standard 1812 footprint, facilitating design flexibility in compact electronics.

Replacement Considerations

Direct substitutes must match the 2700 pF capacitance, 50 VDC rating, and feed-through form factor. Verify that alternative components maintain similar X7R dielectric properties and current handling capabilities. Ensure physical dimensions remain compatible with existing PCB footprints.
