1806J1000331MCTE01

Overview

The Knowles Syfer 1806J1000331MCTE01 is a three-terminal feed-through capacitor designed for surface mount technology. It features a capacitance of 330 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes C0G (NP0) dielectric material to ensure stability across its operating temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it measures 4.5 mm in length, 1.6 mm in width, and 1.1 mm in height. This Class 1 ceramic capacitor is intended for high-frequency noise suppression applications.

Feature Summary

• Three-terminal EMI filter architecture providing enhanced high-frequency noise attenuation compared to standard two-terminal capacitors.
• C0G (NP0) dielectric construction ensures minimal capacitance variation over temperature and voltage changes.
• Flexible terminal design accommodates mechanical stress and reduces the risk of solder joint cracking during thermal cycling.

Applications

• High-speed digital signal line filtering
• RF circuit power supply decoupling
• EMI suppression in communication equipment

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm termination plating and packaging details. Ensure the ordering quantity aligns with the specified reel or cut tape requirements. Cross-reference the Mouser part number 843-1806J1000331MC1 for accurate sourcing information. Confirm RoHS compliance status through the latest product documentation before integration into production.

Selection Notes

Select this component when superior high-frequency performance is required over standard MLCCs. The three-terminal structure offers lower effective series inductance, making it suitable for frequencies where parasitic inductance limits standard capacitor effectiveness. Consider the 1806 footprint constraints and the need for ground plane integration to maximize shielding efficacy.
