1206J1000332MJTE03

Overview

The Knowles Syfer 1206J1000332MJTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 1206 (3216 metric) case size with a capacitance of 3.3 nF and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, providing a capacitance tolerance of ±20%. It operates within a temperature range of -55°C to +125°C and employs nickel barrier terminations with 100% tin plating. This part belongs to the X2Y capacitor filter series, integrating three-terminal filtering capabilities within a standard two-terminal footprint.

Feature Summary

• Integrates X2Y three-terminal EMI filtering architecture within a standard two-terminal SMD package
• Utilizes nickel barrier termination structure with 100% tin plating for enhanced solderability
• Constructed with X7R dielectric material for stable performance across specified operating temperatures

Applications

• High-frequency noise suppression in sensitive electronic circuits
• EMI/RFI filtering in power supply input stages
• Signal line protection in communication equipment

Procurement Notes

Verify the specific suffix 'MJTE03' against official datasheets to confirm the X2Y configuration and termination specifications. Ensure compatibility with PCB footprints designed for three-terminal devices despite the two-terminal appearance. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when space-constrained designs require effective common-mode noise attenuation without increasing board area. The X2Y topology offers superior high-frequency performance compared to standard MLCCs. Consider the ±20% tolerance and X7R characteristics for applications where precise capacitance stability is less critical than broad-spectrum noise reduction.

Part Context

This component is part of the Knowles Syfer high-reliability MLCC portfolio, specifically categorized under X2Y capacitor filters. It represents a specialized class of capacitors that combine energy storage with electromagnetic interference suppression. The 1206 form factor allows for automated surface-mount assembly while maintaining robust mechanical integrity in demanding environments.
