1206J0250102MCTE01

Overview

The Knowles Syfer 1206J0250102MCTE01 is a surface-mount three-terminal feedthrough capacitor designed for EMI suppression. It features a C0G (NP0) dielectric with a capacitance of 1000 pF and a DC voltage rating of 25 VDC. The component operates within a temperature range of -55°C to +125°C and has a tolerance of ±20%. Housed in a standard 1206 (3216 metric) package, it provides high-frequency noise filtering through its integrated ground terminal structure.

Feature Summary

• Three-terminal architecture enables low-inductance grounding for superior high-frequency performance
• C0G/NP0 dielectric ensures stable capacitance characteristics across varying temperatures
• Integrated feedthrough design facilitates effective electromagnetic interference suppression

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise attenuation

Procurement Notes
