1806J0250124MJTE07

Overview

The Knowles Syfer 1806J0250124MJTE07 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 0.12 µF with a tolerance of ±20%. The device operates at a DC voltage rating of 25 VDC and utilizes X7R dielectric material. It supports a current rating of 2 A and is housed in an 1806 (4516 metric) package.

Feature Summary

• Integrates feed-through filtering functionality within a single surface-mount component to suppress electromagnetic interference.
• Incorporates a nickel barrier structure to enhance reliability and protect against corrosion in demanding environments.

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply input/output noise suppression
• Electromagnetic interference mitigation in communication systems

Procurement Notes

Verify the specific ordering suffix to confirm the presence of the nickel barrier and terminal configuration, as these attributes define the component's environmental resilience. Ensure the selected variant matches the required current handling capability and package dimensions for the target PCB layout. Cross-reference the manufacturer datasheet to validate compliance with RoHS standards and operating temperature ranges before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require integrated filtering without additional discrete components. The 1806 footprint offers a balance between current capacity and board area. Consider the X7R dielectric characteristics for applications requiring stable capacitance over moderate temperature variations while maintaining high volumetric efficiency.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines passive filtering with structural robustness. Unlike standard MLCCs, it provides a direct path for signal transmission while shunting noise to ground. The product line targets industries requiring high reliability and compact form factors for advanced electronic assemblies.

Replacement Considerations

Direct substitutes must match the 0.12 µF capacitance, 25 VDC rating, and 1806 package dimensions. Verify that alternative feed-through capacitors support the same 2 A current rating and include nickel barrier protection if environmental durability is required.
