1812J0500562MJTE03

Overview

The Knowles Syfer 1812J0500562MJTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a capacitance of 5.6 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It incorporates a nickel barrier electrode structure with 100% tin terminations and is configured as an X2Y capacitor for enhanced electromagnetic interference suppression.

Feature Summary

• X2Y architecture integrates two capacitors and one resistor in a single monolithic structure for simultaneous noise filtering
• Nickel barrier electrode technology ensures reliable solderability and robust mechanical integrity
• 100% tin termination finish provides compatibility with standard surface mount assembly processes

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Electromagnetic interference (EMI) filtering in signal lines
• Power supply decoupling applications requiring compact footprint solutions

Procurement Notes

Verify the complete part number including the suffix E03 to confirm the specific reel packaging configuration. Ensure the design supports the X2Y topology requirements rather than standard two-terminal capacitor layouts. Confirm that the nickel barrier construction aligns with the intended manufacturing process and environmental conditions.

Selection Notes

Select this component when space-constrained designs require combined filtering and decoupling functions. The X2Y structure offers superior high-frequency attenuation compared to discrete components. Verify that the 50V rating and 5.6nF value meet the circuit specifications while ensuring the 1812 package fits the available PCB real estate constraints.

Part Context

This component belongs to the Knowles Syfer X2Y series, which combines passive elements into a single chip. The 1812J prefix indicates the 1812 case size and general product line classification within the manufacturer's portfolio. The MJTE03 suffix defines the specific termination and packaging details for this variant.

Replacement Considerations

Direct replacements must match the X2Y topology and 1812 dimensions. Standard two-terminal MLCCs cannot replicate the integrated filtering function. Verify equivalent capacitance, voltage rating, and terminal compatibility before substitution.
