1812J5000103MJTE03

Overview

The Knowles Syfer 1812J5000103MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric and a 10 nF nominal capacitance. It operates at a DC voltage rating of 50 V with a tolerance of ±20%. The component utilizes a 1812 (4532 metric) case size, measuring 4.5 mm in length, 3.2 mm in width, and 2.5 mm in height. It employs standard SMD/SMT terminations and is packaged in reels for automated assembly.

Feature Summary

• X2Y capacitor architecture providing enhanced electromagnetic interference filtering capabilities
• Nickel barrier electrode structure ensuring reliable solderability
• 100% tin terminal finish for corrosion resistance and lead-free compliance

Applications

• High-frequency noise suppression in electronic circuits
• Electromagnetic interference (EMI) filtering applications
• General-purpose decoupling in surface-mount designs

Procurement Notes

Verify the specific suffix 'MJTE03' against official Knowles Syfer documentation to confirm the X2Y configuration and termination specifications. Ensure compatibility with automated pick-and-place equipment by confirming reel packaging standards. Cross-reference RoHS compliance status through manufacturer datasheets prior to integration into regulated assemblies.

Selection Notes

Select this component when X2Y topology is required for superior common-mode noise attenuation compared to standard MLCCs. The 50V rating suits low-voltage signal lines. Verify that the 1812 footprint accommodates the physical dimensions within the design constraints. Confirm thermal stability requirements align with the X7R temperature characteristics.

Part Context

This part belongs to the Knowles Syfer general type MLCC series. It represents a specialized variant within the broader capacitor portfolio, distinguished by its unique internal electrode arrangement designed for specific filtering performance rather than standard bulk capacitance storage.
