1206J1000121MCTE07

Overview

The Knowles Syfer 1206J1000121MCTE07 is a feed-through capacitor designed for surface-mount technology. It features a capacitance of 120 pF with a DC voltage rating of 100 V and a tolerance of ±20%. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it supports a current rating of 2 A. This device integrates shielding capabilities directly into the SMD footprint, providing effective electromagnetic interference suppression for high-frequency applications.

Feature Summary

• Integrated feed-through architecture provides inherent shielding against electromagnetic interference
• Supports high-current signal paths with a 2 A rating without compromising filtering performance
• Surface-mount design enables direct integration into PCB layouts for compact form factors

Applications

• High-speed data line filtering in communication equipment
• EMI suppression for USB and HDMI interfaces
• Signal integrity protection in automotive electronics

Procurement Notes

Verify the specific suffix MCTE07 against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the feed-through pad layout. Cross-reference the datasheet for precise soldering thermal profiles to maintain structural integrity during assembly processes.

Selection Notes

Select this component when board space constraints require integrated shielding without additional external ferrite beads or shield cans. The 1206 footprint offers a balance between current handling capacity and miniaturization. Consider the X7R dielectric characteristics for stability across varying temperatures while evaluating the 100 V rating against peak transient voltages in the target circuit.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines MLCC technology with coaxial shielding structures. Unlike standard MLCCs, these components provide superior common-mode noise rejection. The 1206 size represents a standard industry footprint, facilitating replacement in existing designs requiring enhanced EMI performance in limited spaces.
