1206Y0500152MJTE03

Overview

The Knowles Syfer 1206Y0500152MJTE03 is a feed-through ceramic capacitor designed for high-frequency noise suppression. It features a capacitance of 1500 pF with a ±20% tolerance, rated for 50 V DC and a continuous current of 50 mA. The component utilizes C0G/NP0 dielectric material to ensure stable performance across a temperature range of -55°C to +125°C. Housed in a compact 1206 (3216 metric) surface-mount package, it integrates a three-terminal structure to minimize parasitic inductance. This design supports efficient electromagnetic interference filtering in space-constrained electronic assemblies.

Feature Summary

• Three-terminal feed-through architecture for low-inductance signal path
• Integrated EMI filtering capability within the capacitor body
• High thermal stability using C0G/NP0 dielectric material
• Robust mechanical construction suitable for vibration environments

Applications

• RF signal line noise suppression
• Power supply input filtering
• High-speed digital circuit protection
• Aerospace and defense electronics

Procurement Notes

Verify the specific termination configuration and current rating against system requirements before ordering. Confirm that the 50 mA continuous current limit aligns with operational loads. Ensure compatibility with standard reflow soldering profiles for three-terminal components. Check for RoHS compliance status if required by project specifications. Validate footprint dimensions during PCB layout to prevent assembly errors.

Selection Notes

Select this component when simultaneous capacitance and series current handling are required. The feed-through design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the 1206 package size for board space optimization. Evaluate the 50 V rating against peak voltage transients in the application. Assess the need for integrated filtering to reduce component count.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ family, known for flexible terminations that enhance reliability under mechanical stress. The 1206Y series specifically targets high-reliability applications requiring robust performance. As a feed-through capacitor, it differs from standard MLCCs by integrating filtering functionality directly into the component structure. This integration simplifies circuit design by combining decoupling and filtering roles.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and 1500 pF capacitance. Verify equivalent current ratings and voltage specifications. Standard two-terminal capacitors cannot replace this component without altering the circuit design. Consult manufacturer cross-reference lists for verified alternatives.
