1812J5000332MXTE03

Overview

The Knowles Syfer 1812J5000332MXTE03 is a feed-through multilayer ceramic capacitor in an 1812 (4532 metric) package. It features a capacitance of 3300 pF with a 500 VDC rating and utilizes X7R dielectric material. The component supports a maximum current of 50 mA and requires three PCB pads for installation. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates feed-through functionality for high-frequency noise suppression
• Supports direct mounting via three-pad surface mount configuration
• Utilizes X7R dielectric for stable performance across operating temperatures

Applications

• High-frequency noise filtering in RF circuits
• Power supply decoupling requiring integrated shielding
• Signal integrity management in sensitive electronic assemblies

Procurement Notes

Verify the specific MXTE03 suffix against official datasheets to confirm the feed-through variant, as standard MLCC part numbers may differ. Ensure the design accommodates the required three-pad footprint and 50 mA current handling capability. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when simultaneous capacitive filtering and feed-through signal routing are required in a compact form factor. The 1812 package offers a balance between current handling and board space efficiency. Verify that the X7R dielectric characteristics align with the circuit's stability requirements under varying thermal conditions.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, designed for applications demanding effective electromagnetic interference suppression. Unlike standard MLCCs, it integrates a conductive path through the dielectric structure, enabling efficient grounding of high-frequency noise while maintaining signal continuity in critical power or data lines.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific feed-through variant are not available in the provided source data. Cross-referencing with equivalent 1812 feed-through capacitors from other manufacturers requires independent verification of pinout and electrical specifications.
