1806J0250334MXTE07

Overview

The Knowles Syfer 1806J0250334MXTE07 is a feed-through ceramic capacitor designed for surface-mount technology. It features a capacitance of 0.33 µF with a voltage rating of 25 VDC and a current rating of 2 A. The component utilizes an X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it offers high insertion loss characteristics suitable for noise suppression applications.

Feature Summary

• Integrated feed-through architecture combining filtering and decoupling functions within a single surface-mount component.
• High current handling capability of 2 A allows direct integration into power lines without bypass components.
• X7R dielectric material ensures reliable capacitance stability over the specified industrial temperature range.

Applications

• Noise suppression in DC power distribution networks
• EMI/RFI filtering for sensitive electronic circuits
• Power line conditioning in automotive or industrial control systems

Procurement Notes

Verify the specific suffix 'E07' against the manufacturer's latest datasheet to confirm packaging details and terminal specifications. Ensure the selected variant matches the required insertion loss performance for your specific frequency band. Cross-reference the 1806 footprint dimensions with your PCB layout guidelines to guarantee proper solder joint integrity during assembly.

Selection Notes

Select this component when space constraints require a combined filter and decoupling solution. The 2 A current rating makes it suitable for low-to-medium power rails where standard MLCCs would require additional series inductors. Consider the X7R temperature coefficient if operating conditions involve significant thermal fluctuations that might affect capacitance drift in Class 1 alternatives.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor family, which integrates passive filtering elements directly into the component body. Unlike traditional discrete filters, these devices reduce board space and parasitic inductance. The 1806 case size provides a balance between current capacity and footprint efficiency for dense PCB designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative feed-through capacitors by matching the 0.33 µF capacitance, 25 VDC rating, 2 A current limit, and 1806 package dimensions.
