1812J2000823MJTE03

Overview

The Knowles Syfer 1812J2000823MJTE03 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 0.082 µF with a voltage rating of 200 VDC and a maximum current handling capacity of 50 mA. The component utilizes a C0G (NP0) dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Housed in an 1812 (4532 metric) package, it offers high reliability for demanding electronic applications.

Feature Summary

• Integrated feed-through architecture combining filtering and decoupling functions within a single surface-mount component.
• High current handling capability rated at 50 mA, suitable for power line noise suppression.
• Utilizes C0G (NP0) dielectric material for exceptional capacitance stability over varying temperatures and voltages.

Applications

• Power supply input filtering
• Noise suppression on DC power lines
• EMI/RFI mitigation in sensitive electronics

Procurement Notes

Verify the specific suffix MJTE03 against official manufacturer documentation to confirm pin configuration and termination style. Ensure compatibility with PCB pad layouts designed for feed-through components rather than standard MLCCs. Confirm RoHS compliance status through the latest datasheet before integration into regulated products.

Selection Notes

Select this component when board space is limited but high-current filtering is required. The feed-through design reduces parasitic inductance compared to discrete filter combinations. Verify that the 50 mA current rating exceeds the maximum expected load current to prevent device failure during operation.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. It integrates a central conductor with surrounding dielectric and electrode layers to provide inherent low-pass filtering characteristics directly on the power trace.

Replacement Considerations
