1206J0500681MCTE01

Overview

The Knowles Syfer 1206J0500681MCTE01 is a three-terminal surface-mount feedthrough capacitor designed for high-frequency EMI suppression. It features a C0G (NP0) dielectric with a capacitance of 680 pF and a DC voltage rating of 50 VDC. The component operates within a temperature range of -55°C to +125°C and utilizes a 1206 (3216 metric) package footprint. It includes an internal inductor structure providing attenuation, specifically rated at 30 dB attenuation at 100 MHz.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• C0G (NP0) dielectric ensures stable capacitance performance across varying temperatures and voltages.
• Integrated inductive element creates a low-pass filter response for effective EMI suppression.

Applications

• RF circuit filtering
• High-speed digital signal line decoupling
• Power supply input filtering for sensitive electronics

Procurement Notes

Verify the specific suffix 'MCTE01' against official Knowles Syfer documentation to confirm packaging type and terminal finish specifications. Ensure the design accommodates the three-pad footprint required for proper grounding and signal path connection. Confirm RoHS compliance status through current manufacturer declarations prior to final procurement.

Selection Notes

Select this component when high attenuation is required in a compact SMD form factor. The 1206 package allows for space-constrained designs while maintaining robust electrical performance. Consider the 50V rating and 680pF value for compatibility with system voltage levels and frequency response requirements.
