1206J0500183MJTE03

Overview

The Knowles Syfer 1206J0500183MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.018 µF with a DC voltage rating of 50 V and a rated current of 50 mA. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it employs a three-terminal architecture with nickel barrier and tin terminations to provide effective EMI filtering in compact circuit layouts.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency noise attenuation
• X7R ceramic dielectric ensures thermal stability within the specified operating range
• Nickel barrier and tin termination structure supports reliable surface-mount assembly

Applications

• EMI filtering in portable electronic devices
• Noise suppression in automotive infotainment systems
• Signal integrity protection in industrial control circuits

Procurement Notes

Verify that the specific suffix MJTE03 corresponds to the required three-terminal feed-through configuration rather than a standard two-terminal MLCC. Confirm that the 50 mA current rating aligns with the application's power dissipation requirements. Ensure the 1206 footprint matches the PCB design constraints. Cross-reference the RoHS compliance status if environmental regulations are mandatory for the target market.

Selection Notes

Select this component when high-frequency noise reduction is critical in space-constrained designs. The three-terminal structure offers superior RF performance compared to standard capacitors. Consider the 50 mA current limit when designing for power lines. The X7R dielectric provides a balance between capacitance density and temperature stability suitable for general-purpose applications.
