1806J1000123MJTE07

Overview

The Knowles Syfer 1806J1000123MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.012 µF with a ±20% tolerance and a DC voltage rating of 100 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1806 (4516 metric) package, it integrates a three-terminal architecture to provide effective electromagnetic interference filtering.

Feature Summary

• Integrates a three-terminal feed-through structure for enhanced high-frequency noise attenuation
• Utilizes C0G (NP0) ceramic dielectric for minimal capacitance variation over temperature and voltage
• Features nickel barrier terminations compatible with standard surface-mount reflow processes

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific termination finish and lead-free compliance status against the manufacturer's current datasheet before integration. Confirm that the 1806 footprint dimensions align with the target PCB layout constraints. Ensure the selected variant matches the required capacitance tolerance and voltage derating specifications for the intended application environment.

Selection Notes

Select this component when compact EMI filtering is required on high-speed lines without significant signal degradation. The C0G dielectric ensures predictable behavior in precision analog or RF circuits. Evaluate the trade-off between the 1806 package size and the required capacitance value compared to alternative series offerings from the manufacturer.

Part Context

This part belongs to the Knowles Syfer J-series of feed-through capacitors, which are engineered for superior high-frequency performance. These components are distinct from standard multilayer ceramic capacitors by their internal ground plane design, offering lower parasitic inductance. The series is widely used in telecommunications and computing infrastructure requiring robust signal integrity.

Replacement Considerations

Consult official substitution guides for equivalent 1806 feed-through capacitors with matching 100V ratings and 0.012 µF capacitance. Verify terminal compatibility and thermal resistance characteristics when considering alternatives.
