1206J0500104MJTE07

Overview

The Knowles Syfer 1206J0500104MJTE07 is a Class 1 multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 100 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a DC voltage of 50V and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a three-terminal architecture with nickel barrier and 100% tin terminations. This configuration functions as an EMI filter, providing effective noise suppression in compact electronic assemblies.

Feature Summary

• Three-terminal structure enables integrated EMI filtering capabilities
• Nickel barrier termination system ensures reliable solderability
• X7R dielectric provides stable performance across wide temperature ranges

Applications

• High-frequency signal line noise suppression
• Power supply input/output filtering
• EMI suppression in automotive electronics

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the nickel barrier termination matches your assembly process requirements. Ensure the 1206 footprint aligns with your PCB design guidelines. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the 50V rating against your circuit's peak operating conditions.

Selection Notes

Select this component when space-constrained EMI filtering is required without adding discrete inductors. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the X7R characteristics for applications requiring moderate stability over temperature variations. Evaluate the 100nF value against your target cutoff frequency requirements for optimal noise reduction performance.

Part Context

This part belongs to the Knowles Syfer 1206J series of feed-through capacitors. These components are engineered specifically for electromagnetic interference suppression in dense circuit layouts. The series combines the benefits of MLCC technology with specialized internal electrode structures to achieve low impedance paths for high-frequency noise.

FAQ

What is the primary function of the three-terminal design?

The three-terminal design creates a low-inductance path for high-frequency noise, effectively acting as an EMI filter while maintaining the physical footprint of a standard capacitor.

Does this component require special mounting considerations?

Yes, proper grounding of the center terminal is critical for optimal EMI performance. The outer terminals connect to the signal lines, while the center terminal must be connected to ground with minimal trace length.
