1806J0500273MXTE07

Overview

The Knowles Syfer 1806J0500273MXTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.027 µF with a voltage rating of 50V DC and a current handling capacity of 2 A. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a compact 1806 (4516 metric) package, it integrates a center pin structure to minimize parasitic inductance. This design facilitates effective electromagnetic interference filtering in dense circuit layouts while maintaining signal integrity.

Feature Summary

• Integrates a center pin feed-through architecture to significantly reduce parasitic inductance for superior high-frequency noise attenuation.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm terminal configuration and termination plating specifications. Ensure that the selected variant matches the required current rating and physical footprint dimensions for the target PCB layout. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when low-inductance filtering is critical for high-speed signals or power rails. The 1806 package offers a balance between current handling capability and board space efficiency. Consider the X7R dielectric characteristics for applications requiring moderate capacitance stability over varying temperatures. Evaluate the 2A current rating against peak load requirements to prevent thermal issues.

Part Context

This part belongs to the Knowles Syfer MLCC feed-through series, which specializes in EMI suppression components. These capacitors combine the benefits of traditional feed-through filters with the convenience of surface-mount technology. The series is engineered for demanding environments where reliable noise reduction and compact form factors are essential for modern electronic designs.

Replacement Considerations

Consult the official Knowles Syfer substitution guide for verified equivalents. Ensure any replacement maintains the same 1806 footprint, 50V rating, and 2A current capacity. Verify that alternative parts offer comparable parasitic inductance values to preserve filter performance.
