1806J0250474MXTE01

Overview

The Knowles Syfer 1806J0250474MXTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 0.47 µF capacitance with a ±20% tolerance and a 25 VDC voltage rating. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a compact 1806 (4516 metric) package, it integrates a built-in current-carrying terminal capable of handling up to 300 mA. This configuration allows the device to function as both a filter and a conductor, providing efficient electromagnetic interference (EMI) reduction in space-constrained applications.

Feature Summary

• Integrates a conductive center pin to carry load current while filtering noise
• Provides effective common-mode EMI suppression in a single compact footprint
• Utilizes X7R ceramic dielectric for stable performance across wide temperature ranges

Applications

• High-speed data line filtering in portable electronics
• Power supply input/output noise suppression
• RF circuit grounding and decoupling
• Automotive infotainment system signal protection

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm terminal configuration and termination plating specifications. Ensure that the required continuous current rating of 300 mA aligns with the thermal management capabilities of the target PCB layout. Cross-reference the RoHS compliance status and lead-free requirements with current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when simultaneous power conduction and signal filtering are required within a limited board area. The 1806 package offers a balance between current capacity and footprint efficiency compared to larger feed-through variants. Consider the X7R dielectric characteristics for applications requiring moderate capacitance stability over varying temperatures and bias voltages.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines the functions of a capacitor and a resistor or inductor into a single monolithic structure. These components are engineered for high-frequency applications where traditional discrete filters would consume excessive space. The series is widely recognized for its reliability in harsh environments and consistent electrical performance.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific model are not available in the provided source data. Verify compatibility with alternative feed-through capacitors by matching the 1806 package dimensions, 0.47 µF capacitance value, 25 VDC rating, and 300 mA current carrying capability.
