1206J2000271MCTE03

Overview

The Knowles Syfer 1206J2000271MCTE03 is a feed-through multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) surface-mount package. It features a capacitance of 270 pF with a voltage rating of 200 VDC and a current rating of 50 mA. The component utilizes C0G/NP0 dielectric technology for stable performance across temperatures ranging from -55°C to +125°C. Designed for high-frequency applications, it offers low equivalent series resistance (ESR) and inductance (ESL), providing effective electromagnetic interference (EMI) suppression in compact circuit layouts.

Feature Summary

• Integrated feed-through architecture combining filtering and mounting functions
• Low parasitic inductance and resistance for high-frequency signal integrity
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature
• Robust construction suitable for harsh environmental conditions

Applications

• RF and microwave circuit filtering
• High-speed digital signal line decoupling
• Electromagnetic interference (EMI) suppression modules
• Telecommunications equipment signal conditioning

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm terminal configuration and packaging details. Ensure design compatibility with 1206 footprint dimensions and thermal requirements. Confirm that the 50 mA current rating meets application demands. Cross-reference manufacturer part numbers directly to avoid substitution errors with similar MLCC types.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering without additional discrete components. The feed-through structure reduces board area compared to traditional capacitors. Evaluate the 200 VDC rating against peak voltage transients. Consider the C0G stability for precision timing or RF applications where capacitance drift is unacceptable.

Part Context

This part belongs to the Knowles Syfer 1206J series of feed-through capacitors. These components are engineered for high-reliability applications requiring superior noise suppression in small form factors. The series leverages advanced ceramic processing to achieve consistent electrical characteristics across production batches.

Replacement Considerations

Direct substitutes must match the 1206 feed-through form factor, 270 pF capacitance, and 200 VDC rating. Verify terminal metallurgy and current handling capabilities. Generic MLCCs lack the integrated feed-through filtering properties and may not provide equivalent EMI performance.
