Overview
The Knowles Syfer 1206Y0250223MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 22 nF with a tolerance of ±20% and an X7R dielectric material. The component is rated for a maximum DC voltage of 25V and operates within a temperature range of -55°C to +125°C. It utilizes the FlexiCap technology with nickel barrier termination, providing enhanced mechanical reliability in board-flex sensitive applications.
Feature Summary
- Three-terminal architecture functions as an integrated EMI filter to suppress electromagnetic interference.
- FlexiCap flexible termination design reduces stress on the component during PCB flexing.
- Nickel barrier plating provides robust solderability and corrosion resistance.
Applications
- Board-flex sensitive electronic assemblies
- High-density circuit boards requiring EMI suppression
- Automotive electronics systems
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm terminal composition and packaging details. Ensure compatibility with automated pick-and-place equipment due to the reel packaging format. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated supply chains.
Selection Notes
Select this component when both capacitance filtering and EMI suppression are required in a single footprint. The three-terminal design offers superior high-frequency noise attenuation compared to standard two-terminal capacitors. Consider the 25V rating and X7R characteristics for stability in moderate voltage environments.
Part Context
This part belongs to the Knowles Syfer 1206Y series of FlexiCap MLCCs. The series is engineered for reliability in demanding environments, combining standard capacitor functionality with passive filtering capabilities. The 1206 package size allows for compact layout designs while maintaining sufficient power handling and voltage ratings.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source data. Verify pinout compatibility and electrical specifications before considering alternative manufacturers or generic equivalents.
FAQ
What is the primary function of the three-terminal design?
The three-terminal configuration allows the component to act as an EMI filter, providing signal path isolation and noise suppression more effectively than standard two-terminal capacitors.
How does FlexiCap technology benefit the component?
FlexiCap technology uses flexible terminations that absorb mechanical stress, preventing cracking and failure in applications where the printed circuit board may flex or warp during operation.
