1812J5000272MJTE03

Overview

The Knowles Syfer 1812J5000272MJTE03 is a feed-through multilayer ceramic capacitor designed for surface-mount applications. It features a capacitance of 2700 pF with a DC voltage rating of 500 VDC and a maximum current rating of 50 mA. The component utilizes an X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it offers a compact footprint suitable for high-density circuit board layouts.

Feature Summary

• Integrates feed-through architecture to provide effective electromagnetic interference suppression within a single surface-mount component.
• Utilizes X7R dielectric material to maintain capacitance stability under varying thermal conditions.
• Supports continuous current loads up to 50 mA, enabling direct integration into power signal paths.

Applications

• Electromagnetic interference filtering in high-frequency electronic circuits
• Power supply input and output decoupling stages
• Signal line protection in communication equipment

Procurement Notes

Verify the specific suffix MJTE03 against official manufacturer documentation to confirm the feed-through configuration and terminal style. Ensure the selected variant matches the required 50 mA current rating and 1812 package dimensions for your PCB layout. Cross-reference the datasheet for precise termination specifications before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a combined filtering and mounting solution. The 1812 package provides a balance between capacitance value and physical size. Confirm that the 500 VDC rating exceeds the peak operating voltage of the target application to ensure long-term reliability and prevent dielectric breakdown.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines passive filtering capabilities with mechanical mounting. Unlike standard MLCCs, these components are engineered to handle higher currents while maintaining low impedance characteristics. They are distinct from general-purpose capacitors due to their specialized internal structure designed for noise attenuation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative feed-through capacitors by matching the 2700 pF capacitance, 500 VDC rating, 50 mA current limit, and 1812 package dimensions.
