1806J0500470MCTE01

Overview

The Knowles Syfer 1806J0500470MCTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a C0G (NP0) dielectric material, ensuring stable capacitance characteristics across varying temperatures and voltages. The component operates within a temperature range of -55°C to +125°C and carries a DC voltage rating of 50 VDC. With a nominal capacitance of 47 pF and a tolerance of ±20%, it 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. The device utilizes standard SMD/SMT terminations and is supplied in reel packaging.

Feature Summary

• Utilizes C0G (NP0) dielectric for minimal capacitance variation over temperature and voltage changes
• Constructed with standard SMD/SMT terminations for reliable surface-mount integration
• Designed for high-reliability environments requiring stable Class 1 capacitor performance

Applications

• High-frequency RF circuit tuning and filtering
• Precision timing and oscillator circuits requiring low drift
• General-purpose decoupling in sensitive analog signal paths

Procurement Notes

Verify the specific suffix 'MCTE01' against official Knowles Syfer documentation to confirm terminal configuration and packaging details. Ensure compatibility with PCB footprint dimensions for the 1806 case size. Confirm RoHS compliance status through current datasheets before final procurement approval.

Selection Notes

Select this component when a stable, low-loss capacitor is required for high-frequency applications. The C0G dielectric ensures predictable behavior in resonant circuits. Verify that the 50 VDC rating exceeds the peak operating voltage in the target application to maintain reliability and prevent dielectric breakdown under transient conditions.

Part Context

This part belongs to the Knowles Syfer MLCC portfolio, specifically engineered for demanding electronic environments. The 1806J series indicates a general-type high-reliability capacitor line. These components are widely used in aerospace, defense, and industrial sectors where long-term stability and strict quality standards are mandatory for critical system operations.

Replacement Considerations

Consult official substitution guides for equivalent 1806 C0G capacitors from Knowles Syfer or other manufacturers. Ensure replacement parts match the 47 pF value, 50 VDC rating, and ±20% tolerance while maintaining compatible physical dimensions and termination styles.
