1206J2000183MXTE07

Overview

The Knowles Syfer 1206J2000183MXTE07 is a three-terminal X2Y integrated surface mount EMI filter capacitor housed in a 1206 (3216 metric) package. It features an X7R dielectric with a capacitance of 18 nF and a tolerance of ±20%. The component is rated for a DC voltage of 200V and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier electrode structure with 100% tin terminations, designed for high-frequency noise suppression in compact electronic assemblies.

Feature Summary

• Three-terminal X2Y architecture providing simultaneous common-mode and differential-mode noise filtering
• Nickel barrier electrode construction ensuring robust mechanical integrity and solderability
• Integrated surface mount design replacing multiple discrete components to reduce board space

Applications

• High-speed data line protection in consumer electronics
• Power supply input filtering for portable devices
• Signal integrity enhancement in automotive infotainment systems

Procurement Notes

Verify the specific suffix configuration against official Knowles Syfer documentation to confirm terminal material and barrier layer specifications. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format. Cross-reference the 1206 footprint dimensions with your PCB layout guidelines to guarantee proper clearance and solder joint reliability during assembly processes.

Selection Notes

Select this component when space-constrained designs require combined common-mode and differential-mode attenuation without using multiple discrete capacitors. The X7R dielectric offers stable performance across the specified industrial temperature range. Consider the 200V rating for applications requiring higher voltage margins than standard low-voltage filters provide.

Part Context

This part belongs to the Knowles Syfer X2Y series of integrated EMI filters. These components utilize a unique internal electrode structure to create three terminals within a single ceramic body. The series is engineered to replace traditional LC filters or multiple capacitor arrangements, offering superior high-frequency noise suppression in a minimal footprint suitable for modern miniaturized electronics.
