1206Y1000122MJTE03

Overview

The Knowles Syfer 1206Y1000122MJTE03 is a surface-mount feed-through capacitor in a 1206 (3216 metric) package. It features a capacitance of 1200 pF with a tolerance of ±20%. The component has a DC voltage rating of 100 V and utilizes X7R dielectric material. Designed for high-frequency applications, it supports a maximum current of 50 mA. The device operates within a temperature range of -55°C to +125°C and includes nickel barrier termination technology.

Feature Summary

• Integrated feed-through architecture provides effective electromagnetic interference filtering within a compact footprint.
• Nickel barrier termination structure ensures reliable solderability and mechanical stability during assembly.
• X7R dielectric composition maintains stable electrical performance across the specified industrial temperature range.

Applications

• High-frequency signal line noise suppression
• Power distribution network filtering
• Automotive electronics EMI mitigation

Procurement Notes

Verify the specific suffix 'JTE03' against official datasheets to confirm the feed-through configuration and nickel barrier terminations. Ensure that the 50 mA current rating aligns with the target circuit requirements. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when board space constraints require a combined decoupling and filtering solution. The 1206 form factor suits automated pick-and-place processes. Consider the 50 mA limit for power lines and verify impedance characteristics at the operating frequency to ensure adequate attenuation.

Part Context

This part belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability multilayer ceramic capacitors. The series incorporates specialized termination technologies to enhance durability in demanding environments, distinguishing these components from standard passive capacitors.

Replacement Considerations

Direct substitutes must match the 1206 feed-through form factor, 1200 pF value, and 100 V rating. Verify compatibility of the nickel barrier termination and X7R dielectric properties to maintain original circuit performance and reliability standards.
