1206J1000222MJTE03

Overview

The Knowles Syfer 1206J1000222MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in a 1206 package. It features a capacitance of 2200 pF with a tolerance of ±20%. The component has a DC voltage rating of 100 V and utilizes X7R dielectric material. It is designed for operation within a temperature range of -55°C to +125°C. This specific variant incorporates a nickel barrier electrode structure and is classified as an X2Y capacitor, providing three-terminal functionality for enhanced electromagnetic interference filtering.

Feature Summary

• X2Y three-terminal architecture for integrated common-mode noise suppression
• Nickel barrier internal electrodes for improved reliability
• Surface mount SMD/SMT construction for automated assembly

Applications

• High-frequency signal line filtering
• Power supply decoupling in noisy environments
• Electromagnetic interference (EMI) suppression circuits

Procurement Notes

Verify the complete part number including the suffix to ensure the correct electrode and termination specifications are selected. Confirm that the supplier provides official documentation from Knowles Syfer or authorized distributors. Check for RoHS compliance status and lead times directly with the vendor, as availability may vary by region.

Selection Notes

Select this component when a compact three-terminal solution is required for EMI filtering in space-constrained designs. The X2Y configuration offers superior performance compared to standard two-terminal capacitors in high-noise applications. Ensure the 100V rating and X7R temperature characteristics align with the circuit requirements.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC family. The '1206' designation indicates the standard imperial case size. The 'J' typically denotes the tolerance code, while '1000' refers to the voltage rating. The 'MJTE03' suffix specifies the nickel barrier construction and terminal finish, distinguishing it from other variants in the series.

Replacement Considerations

Direct substitutes include the 1206Y1000222MSTE03 and 1206J1000222MJTE03 from the same manufacturer. Verify that any replacement maintains the X2Y topology and nickel barrier electrode structure to ensure equivalent electrical performance and mechanical compatibility.
