1206J0500820MCTE01

Overview

The Knowles Syfer 1206J0500820MCTE01 is a three-terminal surface-mount feedthrough capacitor designed for electromagnetic interference (EMI) filtering. It features a capacitance of 82 pF with a voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a compact 1206 (3216 metric) package, it integrates a low-inductance internal structure to provide effective high-frequency noise suppression in sensitive electronic circuits.

Feature Summary

• Three-terminal architecture provides inherent low-inductance path for superior high-frequency EMI attenuation
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes
• Compact 1206 footprint allows integration into space-constrained printed circuit board layouts

Applications

• High-speed digital signal line filtering
• RF circuit power supply decoupling
• Sensitive analog input protection

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm terminal configuration and termination plating specifications. Ensure that the selected packaging format aligns with automated assembly requirements. Cross-reference the datasheet for precise mechanical dimensions and recommended soldering profiles to maintain component integrity during installation.

Selection Notes

Select this component when low parasitic inductance is critical for maintaining signal integrity at high frequencies. The three-terminal design offers better performance than standard two-terminal capacitors in EMI applications. Confirm that the 50V DC rating exceeds the maximum circuit voltage and that the 82 pF value matches the required filter characteristics for the target frequency band.

Part Context

This part belongs to the Knowles Syfer E01 series of SMT EMI filters. The series is engineered for high-reliability applications requiring consistent performance under thermal stress. The 1206J prefix indicates the case size and voltage class within the broader Syfer portfolio of ceramic capacitors.
