1206Y1000222MJTE03

Overview

The Knowles Syfer 1206Y1000222MJTE03 is a feed-through multilayer ceramic capacitor designed for high-frequency noise suppression. It features a capacitance of 2200 pF with a ±20% tolerance and an X7R dielectric material. The component is rated for a DC voltage of 100V and supports a maximum current of 50 mA. Housed in a 1206 (3216 metric) surface-mount package, it operates within a temperature range of -55°C to +125°C. This device integrates a nickel barrier structure and utilizes FlexiCap technology to enhance mechanical reliability under board flex conditions.

Feature Summary

• Integrates a conductive feed-through path for direct signal line filtering without additional circuitry
• Utilizes FlexiCap technology with soft terminations to mitigate stress from PCB bending
• Incorporates a nickel barrier layer to prevent electrode migration and ensure long-term stability
• Provides effective common-mode noise attenuation in compact surface-mount form factors

Applications

• High-speed data interface lines requiring integrated EMI suppression
• Automotive electronic systems subject to mechanical vibration and board flex
• Industrial control circuits demanding robust noise immunity
• Telecommunications equipment signal conditioning paths

Procurement Notes

Verify the specific suffix codes against official Knowles Syfer documentation to confirm terminal configuration and barrier specifications. Ensure the selected variant matches the required current rating and capacitance tolerance for the target application. Cross-reference the AEC-Q200 qualification status if automotive compliance is mandatory. Confirm package dimensions align with the intended PCB footprint design constraints.

Selection Notes

Select this component when space-constrained designs require simultaneous signal routing and noise filtering. The feed-through architecture eliminates the need for separate shunt capacitors, reducing board area. Consider the 50 mA current limit during initial circuit planning to avoid thermal issues. The X7R dielectric offers stable performance across the specified industrial temperature range for general-purpose filtering tasks.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in flexible termination MLCCs for sensitive applications. The 1206Y prefix indicates the standard 1206 case size family. As a feed-through capacitor, it differs from standard MLCCs by providing a low-impedance path through the center conductor while shunting high-frequency noise to ground via the outer electrodes.

Replacement Considerations

Direct substitutes must match the 1206 feed-through form factor, 2200 pF capacitance, and 100V rating. Verify that alternative parts support the same 50 mA current handling capability and include nickel barrier protection. Ensure replacement components maintain equivalent FlexiCap flexibility characteristics to preserve mechanical reliability in flex-sensitive assemblies.
