1812J0500332MJTE03

Overview

The Knowles Syfer 1812J0500332MJTE03 is a feed-through multilayer ceramic capacitor designed for high-frequency noise suppression. It features a capacitance of 3300 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) surface-mount package, it integrates a three-pad configuration to facilitate efficient grounding and signal routing.

Feature Summary

• Integrates feed-through architecture for effective electromagnetic interference filtering
• Utilizes X7R dielectric for stable capacitance performance across operating temperatures
• Features a three-pad surface-mount design for optimized board layout and grounding

Applications

• High-frequency noise suppression in electronic circuits
• Signal integrity management in communication systems
• Electromagnetic interference filtering in sensitive electronics

Procurement Notes

Verify the specific suffix 'E03' confirms the feed-through variant with the required three-pad footprint. Ensure compatibility with PCB land patterns designed for this unique terminal configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production assemblies.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete components. The feed-through structure simplifies layout compared to standard MLCCs. Verify that the 50V rating and 3300pF value meet circuit requirements. Consider the 1812 package size constraints during mechanical design phase.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. It combines capacitance with low-inductance grounding via its central terminal. The 1812J prefix indicates the general type family, while the specific suffix defines the feed-through construction and termination style.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout and electrical specifications carefully if considering alternative feed-through capacitors from other manufacturers.
