1806J0500222MCTE01

Overview

The Knowles Syfer 1806J0500222MCTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 2200 pF with a ±20% tolerance 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 standard 1806 (4516 metric) package, it incorporates three terminals for effective filtering. The device supports a current rating of 300 mA and offers insertion loss characteristics suitable for high-frequency noise attenuation.

Feature Summary

• Three-terminal feed-through architecture provides enhanced electromagnetic interference suppression compared to standard two-terminal capacitors.
• C0G (NP0) dielectric construction ensures minimal capacitance variation over temperature changes and applied voltage.
• Surface-mount design facilitates automated assembly and integration into compact electronic circuits.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• EMI suppression in automotive electronics and industrial control systems

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal plating and packaging variations. Ensure that the selected variant matches the required insertion loss specifications for the target frequency band. Cross-reference the RoHS compliance status with the latest environmental declarations provided by Knowles Syfer before finalizing procurement orders.

Selection Notes

Select this component when superior common-mode noise rejection is required in space-constrained designs. The three-terminal structure allows for lower parasitic inductance, making it ideal for frequencies where standard MLCCs may exhibit reduced effectiveness. Consider the 50V rating and 2200pF value to ensure compatibility with the circuit's impedance and voltage requirements without derating issues.
