1206J0500471MCTE07

Overview

The Knowles Syfer 1206J0500471MCTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 470 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes a C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it employs a three-terminal feed-through architecture with nickel barrier and 100% tin terminations. This design provides effective electromagnetic interference (EMI) filtering capabilities while maintaining low parasitic inductance.

Feature Summary

• Three-terminal feed-through structure for enhanced EMI suppression
• C0G (NP0) dielectric for minimal capacitance variation over temperature
• Nickel barrier termination system for reliable soldering
• High-reliability construction suitable for demanding environments

Applications

• RF circuit impedance matching networks
• High-frequency signal coupling and decoupling
• EMI filtering in sensitive electronic systems
• Precision timing and oscillator circuits

Procurement Notes

Verify the specific suffix MCTE07 against official Knowles Syfer documentation to confirm the three-terminal feed-through configuration and termination materials. Ensure compatibility with PCB layout requirements for 1206 footprint dimensions. Confirm RoHS compliance status through current manufacturer datasheets prior to integration into production designs.

Selection Notes

Select this component when high-frequency stability and superior EMI attenuation are required in a compact form factor. The C0G dielectric ensures consistent capacitance values under varying thermal conditions. Consider the three-terminal topology for improved grounding paths compared to standard two-terminal capacitors. Validate that the 50V rating meets the maximum circuit voltage peaks including transients.
