1812Y5000273MSTE03

Overview

The Knowles Syfer 1812Y5000273MSTE03 is a feed-through multilayer ceramic capacitor with a capacitance of 0.027 µF and a DC voltage rating of 500 V. It utilizes a 1812 (4532 metric) surface-mount package and features three pads for mounting. The component is designed to handle a current rating of 50 mA, providing effective electromagnetic interference filtering in high-reliability applications.

Feature Summary

• Integrates feed-through architecture for enhanced signal integrity
• Provides high current handling capability of 50 mA
• Features a compact 1812 surface-mount footprint

Applications

• High-frequency signal filtering in communication systems
• Power supply input/output decoupling
• Electromagnetic interference suppression in sensitive electronics

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm terminal configuration and material specifications. Ensure compatibility with existing PCB footprints requiring three-pad feed-through designs. Cross-reference part numbers with manufacturer updates to avoid obsolete stock issues.

Selection Notes

Select this component when high-current filtering is required alongside standard MLCC performance. The 500 VDC rating suits medium-voltage circuits. Compare against standard capacitors if feed-through topology is not strictly necessary for EMI reduction.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors due to its integrated grounding structure. It addresses EMI challenges in space-constrained designs where traditional filters are too large.

Replacement Considerations

Direct substitutes require matching 500 VDC, 0.027 µF, and 50 mA ratings. Verify pinout compatibility as feed-through components have unique mounting requirements compared to standard two-terminal capacitors.
