1206J2000332MJTE03

Overview

The Knowles Syfer 1206J2000332MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 3300 pF capacitance with a ±20% tolerance, utilizing X7R dielectric material. The component is rated for a DC voltage of 200 V and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a nickel barrier electrode structure terminated with 100% tin. This specific variant is an X2Y capacitor, providing integrated common-mode filtering capabilities alongside its capacitive function.

Feature Summary

• X2Y architecture integrates three terminals to provide simultaneous differential and common-mode noise suppression within a single compact footprint.
• Nickel barrier electrode construction ensures robust solderability and long-term reliability under thermal stress conditions.
• X7R dielectric offers stable capacitance performance across the specified industrial operating temperature range.

Applications

• High-frequency signal line filtering in automotive electronic control units
• Power supply decoupling in high-density PCB layouts requiring common-mode noise reduction
• EMI suppression circuits in consumer electronics and industrial automation systems

Procurement Notes

Verify that the specific suffix 'T' confirms the X2Y terminal configuration and nickel barrier plating, as these are critical for the intended EMI filtering application. Ensure the X7R dielectric rating aligns with the circuit's thermal environment. Confirm the 200V DC rating meets the system's peak voltage requirements without derating issues. Cross-reference the 1206 footprint dimensions against the design layout to ensure compatibility with automated placement equipment.

Selection Notes

Select this component when both differential and common-mode noise attenuation is required in a space-constrained design. The X2Y topology reduces the number of discrete components needed compared to traditional filter networks. Consider the X7R dielectric characteristics for stability over temperature. The nickel barrier termination is suitable for lead-free soldering processes. Evaluate the 200V rating against the actual circuit voltage to ensure adequate safety margins.

Part Context

This part belongs to the Knowles Syfer 1206J series of high-reliability MLCCs. The series includes various capacitance values and voltage ratings, all sharing the same 1206 footprint and nickel barrier technology. The J prefix indicates the 1206 case size, while the subsequent digits denote voltage and capacitance codes. This specific model represents the X2Y variant within the broader capacitor portfolio.

Replacement Considerations

Direct substitutes include other X2Y capacitors from Knowles Syfer in the 1206 package, such as the 1206J2000332MNT or 1206J2000332FCT, provided they match the required capacitance and voltage ratings. Verify that alternative parts maintain the nickel barrier termination and X7R dielectric specifications to ensure equivalent performance and reliability.
