1812J0500155MXTE07

Overview

The Knowles Syfer 1812J0500155MXTE07 is a high-reliability multilayer ceramic capacitor (MLCC) configured as a feed-through EMI filter. It features a capacitance of 1.5 µF with a ±20% tolerance and an X7R dielectric, rated for 50 VDC. The component utilizes a 1812 (4532 metric) surface-mount package with three terminals to provide effective electromagnetic interference suppression. It operates within a temperature range of -55°C to +125°C and incorporates a nickel barrier with 100% tin termination system.

Feature Summary

• Three-terminal feed-through architecture designed for efficient EMI filtering in compact layouts
• High capacitance density utilizing X7R dielectric material for stable performance
• Nickel barrier and 100% tin termination system ensures reliable solderability and corrosion resistance

Applications

• Electromagnetic interference suppression in sensitive electronic circuits
• Power supply input and output filtering stages
• Signal line noise reduction in communication equipment

Procurement Notes

Verify the specific suffix MXTE07 against the manufacturer datasheet to confirm terminal configuration and termination plating specifications. Ensure the selected variant matches the required lead length and mounting orientation for the target PCB footprint. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when high capacitance values are required in a standard 1812 footprint for EMI applications. The three-terminal design offers superior high-frequency attenuation compared to two-terminal capacitors. Consider the DC bias characteristics of the X7R dielectric to ensure sufficient effective capacitance under operating voltage conditions.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically engineered for high-reliability applications. The 1812J series designation indicates a general-purpose or high-reliability grade within the brand's portfolio. The integration of filtering capabilities into a standard capacitor form factor allows for simplified board layout and reduced component count in noise-sensitive designs.

Replacement Considerations

Direct substitutes must match the 1.5 µF capacitance, 50 V rating, X7R dielectric, and three-terminal feed-through structure. Verify that alternative components support the same 1812 package dimensions and nickel/tin termination systems to maintain compatibility with existing assembly processes.
