1812Y2000184MJTE03

Overview

The Knowles Syfer 1812Y2000184MJTE03 is a feed-through ceramic capacitor designed for surface-mount applications. It features a capacitance of 0.18 µF with a voltage rating of 200 VDC and a current rating of 50 mA. The component utilizes an X7R dielectric material and is housed in a compact 1812 (4532 metric) package. This device integrates a built-in resistor to provide damping characteristics, making it suitable for high-frequency noise suppression circuits.

Feature Summary

• Integrates a built-in resistive element for inherent damping within the capacitor structure
• Utilizes feed-through architecture to combine filtering and resistance functions in a single SMD package
• Constructed with X7R dielectric material for stable performance across operating temperatures

Applications

• High-frequency noise suppression in electronic circuits
• Damping applications requiring integrated resistance and capacitance
• Signal integrity management in sensitive RF environments

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm the integrated resistor value and tolerance. Ensure that the 50 mA current rating and 200 VDC voltage specifications align with the target circuit requirements. Confirm package dimensions match the PCB footprint design. Check for RoHS compliance status in the latest datasheet before finalizing procurement.

Selection Notes

Select this component when a combined filter and damper solution is required in a limited space. The feed-through design simplifies layout by reducing component count. Consider the X7R temperature coefficient if operating conditions vary significantly. Evaluate the 50 mA current handling capability against peak load currents to prevent device failure.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which merges passive filtering with resistive damping. These devices are engineered for surface-mount technology, offering a compact alternative to discrete RC networks. The 1812 form factor provides a balance between electrical performance and board space efficiency.
