1206J1000273MJTE03

Overview

The Knowles Syfer 1206J1000273MJTE03 is a Class 2 Multilayer Ceramic Capacitor (MLCC) in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a capacitance of 27 nF and a DC voltage rating of 100 VDC. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It utilizes Nickel Barrier terminations with 100% tin plating. This specific part number identifies an X2Y capacitor configuration, providing integrated common-mode filtering capabilities alongside standard decoupling functions.

Feature Summary

• X2Y architecture integrating three electrodes for simultaneous signal line filtering and power supply decoupling
• Common-mode noise suppression capability inherent to the X2Y electrode structure
• High reliability construction utilizing nickel barrier termination technology

Applications

• High-speed digital signal line protection against electromagnetic interference
• Power supply decoupling in compact circuit boards requiring minimal footprint
• Automotive electronics systems adhering to AEC-Q200 standards

Procurement Notes

Verify the exact suffix 'MJTE03' during procurement to ensure the X2Y variant is obtained, as standard X7R capacitors share similar base parameters but lack the specialized three-electrode filtering functionality. Confirm RoHS compliance status and check for any regional distribution restrictions that may apply to this specific high-reliability component series before finalizing orders.

Selection Notes

Select this component when board space is constrained and combined filtering and decoupling are required on the same net. The X2Y topology reduces the need for separate ferrite beads or common-mode chokes. Ensure the application voltage does not exceed the 100V DC rating and consider the ±20% tolerance for precision timing circuits where tighter tolerances might be necessary.

Part Context

This component belongs to the Knowles Syfer J-series of high-reliability ceramic capacitors. The series is designed for demanding environments, including automotive and industrial applications. The 1206J1000273MJTE03 specifically represents the X2Y product line within this family, distinguishing it from standard monolithic MLCCs through its unique internal electrode arrangement.
