1806J1000221MCTE01

Overview

The Knowles Syfer 1806J1000221MCTE01 is a surface-mount multilayer ceramic capacitor featuring a 220 pF capacitance with a ±20% tolerance. It operates at a DC voltage rating of 100 VDC and utilizes C0G (NP0) dielectric material for stable performance. The component is housed in an EIA 1806 (4516 metric) package, measuring 4.5 mm in length, 1.6 mm in width, and 1.1 mm in height. Designed as a three-terminal EMI filter, it supports a temperature range from -55 °C to +125 °C.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering capabilities compared to standard two-terminal designs.
• C0G dielectric ensures minimal capacitance variation across varying temperatures and applied voltages.
• Surface-mount construction facilitates automated assembly and integration into compact printed circuit board layouts.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply decoupling in sensitive analog circuits
• Electromagnetic interference suppression in industrial control systems

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and termination material specifications. Ensure that the selected variant matches the required thermal stability class for the intended operating environment. Cross-reference the part number with authorized distributor catalogs to validate current availability status and compliance certifications prior to procurement.

Selection Notes

Select this component when high-frequency noise attenuation is critical within space-constrained designs. The three-terminal structure offers superior grounding paths for RF signals compared to conventional capacitors. Evaluate the physical dimensions against the target footprint to ensure compatibility with existing board layouts and assembly processes.

Part Context

This component belongs to the Knowles Syfer E01 series of feed-through capacitors. These devices are engineered specifically for applications requiring robust EMI suppression in small form factors. The series integrates capacitor functionality with filtering characteristics, providing a compact solution for maintaining signal integrity in dense electronic assemblies.

Replacement Considerations

Direct substitutes must match the 1806 package size, 100V rating, 220pF value, and three-terminal topology. Verify that alternative parts maintain equivalent C0G dielectric properties and thermal ratings to ensure functional parity in existing designs.
