1806J1000102MCTE01

Overview

The Knowles Syfer 1806J1000102MCTE01 is a surface-mount feed-through capacitor designed for EMI filtering. It features a 1000 pF capacitance with a ±20% tolerance and a C0G/NP0 dielectric, ensuring stable performance across temperatures from -55°C to +125°C. Rated for 100 VDC, this component utilizes a 1806 (4516 metric) package size. It supports a maximum current of 300 mA and provides an insertion loss of 27 dB at 100 MHz. The device employs nickel barrier terminations with 100% tin plating for reliable soldering.

Feature Summary

• Three-terminal feed-through architecture providing effective electromagnetic interference suppression
• C0G/NP0 ceramic dielectric material maintaining capacitance stability over wide temperature ranges
• Nickel barrier termination structure compatible with standard surface mount assembly processes

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise suppression in industrial control systems
• EMI mitigation in automotive electronic modules requiring robust thermal performance

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm termination finish and packaging type. Ensure the selected variant matches the required current rating and insertion loss specifications for the target circuit. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly standards.

Selection Notes

Select this component when high-frequency noise attenuation is critical in space-constrained designs. The 1806 footprint offers a balance between capacitance value and board area. Consider the 300 mA current limit when designing power lines. The C0G dielectric is suitable for applications requiring minimal capacitance drift under varying thermal conditions compared to X7R or Y5V types.

Part Context

This part belongs to the Knowles Syfer E01 series of SMT EMI filters. The series is characterized by its three-terminal design, which minimizes parasitic inductance for superior high-frequency performance. These components are widely used in environments demanding reliable noise suppression without compromising signal integrity or occupying excessive PCB real estate.

Replacement Considerations

Direct substitutes must match the 1806 package, 1000 pF capacitance, 100 V rating, and three-terminal feed-through topology. Verify that alternative parts offer comparable insertion loss characteristics and current handling capabilities. Ensure compatibility with existing soldering profiles and mechanical constraints.
