1206J0500223MJTE03

Overview

The Knowles Syfer 1206J0500223MJTE03 is a surface-mount X2Y integrated EMI filter capacitor designed for high-frequency noise suppression. It features a capacitance of 0.022 µF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes an X7R dielectric material, ensuring stable performance across a wide operating temperature range from -55°C to +125°C. Housed in a standard 1206 (3216 metric) package measuring 3.2 mm x 1.6 mm, it offers three terminals for effective common-mode and differential-mode filtering. This device belongs to the E03 series and is suitable for applications requiring compact, reliable electromagnetic interference mitigation.

Feature Summary

• Integrates X2Y technology for simultaneous common-mode and differential-mode noise attenuation within a single compact footprint.
• Provides robust electromagnetic interference (EMI) filtering capabilities suitable for sensitive electronic circuits.
• Features a durable X7R ceramic dielectric that maintains electrical stability under varying thermal conditions.

Applications

• High-speed data line protection in consumer electronics
• Power supply input filtering for portable devices

Procurement Notes

Verify the specific suffix 'E03' against official Knowles Syfer documentation to confirm the exact termination style and packaging configuration. Ensure that the 1206J series designation aligns with your board layout requirements. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require a multi-terminal filter solution in a 1206 package. Consider the 50V DC rating and 0.022 µF capacitance for appropriate circuit impedance matching. Evaluate the thermal environment to ensure operation remains within the specified -55°C to +125°C range. Compare against standard MLCCs if superior EMI suppression characteristics are required for the target application frequency spectrum.

Part Context

This component is part of the Knowles Syfer 1206J series, which specializes in surface-mount feedthrough capacitors. The series integrates X2Y architecture to provide enhanced filtering performance compared to traditional two-terminal capacitors. It serves as a critical passive component for managing electromagnetic compatibility in modern miniaturized electronic systems.

Replacement Considerations
