1206J1000681MCTE01

Overview

The Knowles Syfer 1206J1000681MCTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 680 pF with a ±20% tolerance, rated for 100 VDC. The component utilizes C0G (NP0) dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it supports a maximum current of 300 mA and provides insertion loss of 27 dB at 100 MHz.

Feature Summary

• Integrated three-terminal feed-through architecture for effective electromagnetic interference filtering
• High stability C0G (NP0) ceramic dielectric ensures consistent performance across wide temperature variations
• Low profile surface-mount design facilitates automated assembly on high-density circuit boards

Applications

• High-frequency signal line noise suppression in communication equipment
• Power supply input/output filtering in industrial control systems
• EMI mitigation in automotive electronic modules requiring robust thermal stability

Procurement Notes

Verify the specific suffix MCTE01 against official Knowles Syfer documentation to confirm terminal plating and packaging configuration. Ensure the selected variant matches the required 300 mA current rating and 100 VDC voltage specification for the target application environment. Cross-reference datasheet revisions to confirm compliance with current RoHS standards.

Selection Notes

Select this component when compact EMI filtering is required for signals up to 100 MHz. The 1206 footprint offers a balance between current handling capability and board space efficiency. Consider the 680 pF value for coupling or bypassing applications where precise capacitance stability is critical under varying thermal conditions.
