1206J0500182MCTE01

Overview

The Knowles Syfer 1206J0500182MCTE01 is a surface-mount feedthrough capacitor designed for EMI filtering. It features a capacitance of 1.8 nF with a tolerance of ±20%. The device operates at a DC voltage rating of 50 VDC and utilizes C0G (NP0) dielectric material. It is housed in a 1206 (3216 metric) package, measuring 3.2 mm in length, 1.6 mm in width, and 1.3 mm in height. The component supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Three-terminal SMD architecture providing integrated EMI filtering capabilities
• Nickel barrier electrode structure terminated with 100% tin plating
• C0G/NP0 dielectric ensures stable electrical performance across the operating temperature range

Applications

• High-frequency signal line noise suppression
• Power distribution network decoupling in sensitive circuits
• EMI mitigation in compact electronic modules

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal type and termination material specifications. Ensure the selected variant matches the required capacitance tolerance and voltage rating for the target application environment. Cross-reference manufacturer part numbers with distributor listings to confirm authenticity and current availability status before procurement.

Selection Notes

Select this component when space-constrained designs require integrated filtering without additional discrete components. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Verify that the 50V DC rating exceeds the maximum circuit voltage and consider the thermal management requirements within the -55°C to +125°C operational window.

Part Context

This component belongs to the Knowles Syfer EMI Filter series, specifically utilizing the 1206J base code for the 1206 footprint. It represents a specialized class of multilayer ceramic capacitors engineered for electromagnetic interference suppression rather than general-purpose energy storage or coupling functions.

Replacement Considerations

Direct substitutes must match the 1.8 nF capacitance, 50 VDC rating, 1206 footprint, and three-terminal feedthrough topology. Verify equivalent insertion loss characteristics and termination compatibility.
