1806J0250122MCTE01

Overview

The Knowles Syfer 1806J0250122MCTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a 1200 pF capacitance with a ±20% tolerance, rated for 25 VDC. The component utilizes C0G (NP0) dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4.5mm x 1.6mm) package, it incorporates a three-terminal architecture with nickel barrier and 100% tin terminations.

Feature Summary

• Three-terminal feed-through architecture provides effective electromagnetic interference filtering
• C0G (NP0) dielectric ensures stable capacitance performance across varying temperatures
• Nickel barrier termination system enhances solderability and long-term reliability

Applications

• High-frequency signal line noise suppression
• Power supply input/output filtering
• EMI reduction in sensitive electronic circuits

Procurement Notes

Verify the specific termination finish and package dimensions against your PCB footprint requirements. Confirm that the 25V DC rating aligns with your circuit's maximum operating voltage. Ensure compatibility with your assembly process regarding the 1806 case size and three-terminal configuration.

Selection Notes

Select this component when high-frequency noise attenuation is required in space-constrained designs. The C0G dielectric offers superior stability compared to Class 2 materials. The three-terminal design allows for lower parasitic inductance, improving filter effectiveness at higher frequencies.
