1812Y2000124MJTE03

Overview

The Knowles Syfer 1812Y2000124MJTE03 is a feed-through capacitor designed for surface-mount technology. It features a capacitance of 0.12 µF with a voltage rating of 200 VDC and a current rating of 50 mA. The component utilizes an X7R dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it offers a tolerance of ±20%. This device integrates filtering capabilities directly into the mounting footprint, providing effective electromagnetic interference suppression in compact electronic assemblies.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Utilizes X7R ceramic dielectric for reliable high-frequency noise attenuation
• Supports continuous current handling up to 50 mA for power line applications

Applications

• Electromagnetic interference suppression in compact power supply circuits
• High-frequency noise filtering in automotive electronics
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1812 package dimensions. Cross-reference the latest datasheet for any updates on RoHS compliance status or recommended soldering profiles prior to integration into production designs.

Selection Notes

Select this component when board space is limited but significant high-frequency noise reduction is required on power lines. The integrated feed-through design eliminates the need for separate filter components, simplifying the bill of materials. Consider the 50 mA current rating to ensure the component can handle the operational load without degradation. Verify that the X7R temperature characteristics align with the environmental operating conditions of the target application.

Part Context

This part belongs to the Knowles Syfer 1812Y series of feed-through capacitors. These components are engineered to replace traditional discrete filter arrangements by combining decoupling and filtering functions. The series is widely used in applications demanding robust EMI/RFI performance in small form factors, particularly where through-hole mounting is impractical due to space constraints.
