1206J2000681MCTE01

Overview

The Knowles Syfer 1206J2000681MCTE01 is a three-terminal feed-through capacitor designed for surface mount technology. It features a capacitance of 680 pF with a DC voltage rating of 200 VDC and a current rating of 300 mA. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across its operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package measuring 3.2 mm x 1.6 mm x 1.1 mm, it offers low impedance filtering capabilities suitable for high-frequency noise suppression applications.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering compared to standard two-terminal capacitors
• Feed-through design enabling direct signal path integration for effective common-mode noise reduction
• C0G/NP0 dielectric construction maintaining capacitance stability under varying temperature and voltage conditions

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• Electromagnetic compatibility (EMC) mitigation in automotive electronic modules

Procurement Notes

Verify the specific suffix TE01 against official datasheets to confirm terminal configuration and termination plating specifications. Ensure the selected variant matches the required current rating of 300 mA for the intended circuit application. Cross-reference the 1206 footprint dimensions with PCB layout guidelines to guarantee proper pad placement and soldering reliability during assembly processes.

Selection Notes

Select this component when superior high-frequency attenuation is required over standard MLCCs. The three-terminal structure provides lower parasitic inductance, making it ideal for frequencies where conventional capacitors lose effectiveness. Consider the 200V rating and 680pF value to ensure compatibility with the target signal integrity requirements without introducing excessive loading effects on the driven circuit.

Part Context

This part belongs to the Knowles Syfer E01 series of three-terminal EMI filter capacitors. These components are engineered specifically for suppressing broadband noise in compact surface-mount designs. The 1206 case size allows for dense PCB layouts while maintaining robust electrical performance characteristics essential for modern electronic systems requiring strict emission controls.

Replacement Considerations

Direct substitutes must match the 680 pF capacitance, 200 VDC rating, and three-terminal feed-through topology. Verify that alternative parts support the same 300 mA current handling capability and operate within the -55°C to +125°C temperature range. Ensure physical footprint compatibility with the 1206 (3216 metric) package dimensions.
