1812J2000224MJTE03

Overview

The Knowles Syfer 1812J2000224MJTE03 is a feedthrough capacitor designed for surface-mount applications. It features a capacitance of 0.22 µF with a voltage rating of 200 VDC and a leakage current specification of 50 mA. The component utilizes an X7R dielectric material and is housed in an 1812 (4532 metric) package footprint. This device integrates a built-in resistor to provide damping characteristics, making it suitable for high-frequency noise suppression in compact electronic designs.

Feature Summary

• Integrates a built-in resistor for effective damping and noise suppression
• Utilizes X7R dielectric material for stable performance across temperature ranges
• Designed as a feedthrough capacitor for efficient surface-mount integration

Applications

• High-frequency noise suppression circuits
• Power supply filtering applications
• Compact electronic designs requiring integrated damping

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm the integrated resistor value and tolerance. Ensure that the 50 mA leakage current specification aligns with your circuit requirements. Cross-reference the 1812 footprint dimensions with your PCB layout guidelines to guarantee proper mechanical fit and soldering compatibility during assembly.

Selection Notes

Select this component when a combined filter and damping solution is required in a small form factor. The 200 VDC rating suits low-to-medium voltage DC lines. Consider the X7R temperature coefficient if operating conditions vary significantly. Verify that the integrated resistance meets the specific impedance matching needs of the target application without external components.

Part Context

This component belongs to the Knowles Syfer feedthrough capacitor series, which combines capacitive filtering with resistive damping in a single surface-mount package. These devices are engineered to replace traditional discrete LC filters, saving board space and simplifying assembly processes while maintaining effective high-frequency noise attenuation capabilities.
