0805Y1000122MJTE07

Overview

The Knowles Syfer 0805Y1000122MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 1200 pF with a tolerance of ±20% and operates at a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, ensuring stability across a temperature range of -55°C to +125°C. Housed in an 0805 (2012 metric) package, it integrates a built-in 1 A current handling capability. The termination structure employs a nickel barrier with 100% tin plating, suitable for standard reflow soldering processes.

Feature Summary

• Integrated feed-through architecture provides effective common-mode noise attenuation in compact form factors.
• High current handling capacity supports direct integration into power lines without external shunting components.
• X7R dielectric ensures reliable capacitance retention under varying thermal conditions.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF interference suppression in communication modules

Procurement Notes

Verify the specific suffix 'JTE07' against official manufacturer documentation to confirm terminal configuration and reel specifications. Ensure compatibility with automated pick-and-place equipment regarding the 0805 footprint dimensions. Cross-reference RoHS compliance status with the latest datasheet revision prior to procurement.

Selection Notes

Select this component when space-constrained designs require simultaneous power delivery and noise filtration. The 100V rating suits low-voltage DC bus applications. Consider the ±20% tolerance for general-purpose filtering where precise resonance tuning is not critical. Evaluate thermal management requirements given the self-heating effects under continuous 1A load conditions.

Part Context

This part belongs to the Knowles Syfer Y-series, specialized for EMI/RFI suppression. Unlike standard MLCCs, feed-through capacitors offer superior high-frequency performance due to their coaxial internal structure. The 0805 size allows for dense PCB layouts while maintaining robust electrical isolation between input and output terminals.
