1812J1000103MJTE03

Overview

The Knowles Syfer 1812J1000103MJTE03 is a surface-mount multilayer ceramic capacitor featuring an X7R dielectric and a 10 nF nominal capacitance. It operates with a DC voltage rating of 100 VDC and maintains a tolerance of ±20%. Designed for the 1812 (4532 metric) package, it supports standard SMD/SMT termination types. The component functions within a temperature range of -55°C to +125°C.

Feature Summary

• X2Y filter architecture providing integrated common-mode noise suppression
• Three-terminal design enabling enhanced high-frequency performance

Applications

• High-frequency EMI filtering in electronic circuits
• Common-mode noise suppression applications
• Signal integrity management in sensitive electronics

Procurement Notes

Confirm the specific suffix 'MJTE03' matches project requirements, as it defines the terminal configuration and packaging format. Verify that the 1812 footprint aligns with existing PCB layouts. Ensure the X7R dielectric characteristics meet thermal stability needs for the intended operating environment before finalizing procurement.

Selection Notes

Select this component when integrated three-terminal filtering is required to minimize board space compared to discrete solutions. The X2Y structure offers superior high-frequency attenuation. Consider the 100V rating and 10nF value against circuit impedance requirements. Validate that the ±20% tolerance is acceptable for the specific signal processing application.

Part Context

This part belongs to the Knowles Syfer X2Y capacitor family, which utilizes a unique internal electrode structure to function as both a differential and common-mode filter. Unlike standard MLCCs, these components integrate filtering capabilities directly into the passive element, simplifying circuit design and improving electromagnetic compatibility in compact devices.

Replacement Considerations

Direct substitutes require matching the X2Y topology and 1812 package. Verify equivalent capacitance, voltage rating, and terminal configuration. Cross-reference datasheets for identical frequency response characteristics to ensure functional parity in noise suppression applications.
