1806J1000332MXTE01

Overview

The Knowles Syfer 1806J1000332MXTE01 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface mount applications. It features a capacitance of 3300 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. Utilizing C0G (NP0) dielectric material, the component ensures stable performance across an operating temperature range from -55°C to +125°C. The device is housed in a standard 1806 (4516 metric) package size, measuring 4.5 mm in length, 1.6 mm in width, and 1.1 mm in height. This specific part number denotes a three-terminal EMI filter configuration within the E01 series.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering capabilities
• C0G (NP0) dielectric material ensuring high stability and low loss characteristics
• Nickel barrier termination structure compatible with standard surface mount processes

Applications

• High-frequency signal line filtering in communication equipment
• Power supply noise suppression in sensitive analog circuits
• EMI mitigation in automotive electronic control units

Procurement Notes

Verify the complete part number including the E01 series suffix to confirm the three-terminal filter topology. Standard two-terminal MLCCs share similar base codes but lack the specific EMI filtering geometry. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when superior high-frequency attenuation is required compared to standard two-terminal capacitors. The three-terminal design offers lower parasitic inductance, making it suitable for RF and high-speed digital applications. Ensure PCB layout accommodates the additional ground terminal for optimal filtering performance.

Part Context

This component belongs to the Knowles Syfer E01 series of feed-through capacitors. These devices are engineered specifically for EMI suppression rather than general-purpose energy storage. The 1806 footprint provides a balance between current handling capability and board space efficiency for mid-range filtering requirements.

Replacement Considerations

Direct substitutes include other 1806 three-terminal C0G capacitors with matching 3300 pF capacitance and 100 VDC ratings. Verify that alternative parts maintain the same nickel barrier termination and E01 series filtering characteristics to ensure equivalent circuit performance.
