1806J0500561MCTE01

Overview

The Knowles Syfer 1806J0500561MCTE01 is a three-terminal surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 560 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in the 1806 (4516 metric) package, it supports a maximum current of 300 mA. This device integrates filtering capabilities directly into the mounting structure.

Feature Summary

• Three-terminal architecture provides integrated EMI filtering within the surface mount footprint
• C0G (NP0) dielectric ensures high stability and low loss characteristics
• Feed-through design allows signal passage while shunting noise to ground

Applications

• High-frequency signal line filtering
• EMI suppression in sensitive electronic circuits
• Power distribution network decoupling

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm terminal plating and packaging variations. Ensure the selected variant matches the required current rating and capacitance tolerance for the target application. Cross-reference the Mouser part number 843-1806J0500561MC1 for accurate sourcing details.

Selection Notes

Select this component when space-constrained EMI filtering is required on high-speed lines. The three-terminal configuration offers superior high-frequency attenuation compared to standard two-terminal capacitors. Confirm that the 50V rating and 300mA current capacity align with the circuit's operational parameters before integration.
