1206J0500123MJTE07

Overview

The Knowles Syfer 1206J0500123MJTE07 is a multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a capacitance of 12 nF and a tolerance of ±20%. The component has a DC voltage rating of 200 V and operates within a temperature range of -55°C to +125°C. It utilizes a three-terminal design with nickel barrier and 100% tin terminations, functioning as an EMI filter.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference filtering
• Nickel barrier termination system with 100% tin plating for reliable soldering
• X7R dielectric material providing stable capacitance across the operating temperature range

Applications

• Electromagnetic interference suppression in high-density circuit boards
• Power supply input/output filtering stages
• Signal line noise reduction in sensitive electronic equipment

Procurement Notes

Verify the complete part number including the suffix JTE07 to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as distribution may vary by region. Ensure storage conditions align with moisture sensitivity level requirements for lead-free components.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete inductors. The three-terminal structure offers superior high-frequency performance compared to standard two-terminal capacitors. Verify that the 200V rating meets the circuit's peak voltage demands. Consider the 1206 footprint constraints against available board space for the larger three-terminal body size.

Part Context

This component belongs to the Knowles Syfer 1206J series of general-purpose MLCCs. The specific JTE07 suffix denotes the three-terminal EMI filter variant with nickel barrier terminations. It is distinct from standard two-terminal capacitors in the same series due to its internal grounding structure designed for noise attenuation.

FAQ
