1206J2000123MJTE03

Overview

The Knowles Syfer 1206J2000123MJTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a capacitance of 0.012 µF with a DC voltage rating of 200 V and a tolerance of ±20%. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it integrates a built-in resistor element rated at 50 mA to suppress inrush current. This configuration provides effective electromagnetic interference filtering while maintaining compact board space requirements.

Feature Summary

• Integrates a built-in 50 mA resistor element for inrush current suppression within the capacitor structure
• Provides simultaneous energy storage and electromagnetic interference filtering capabilities
• Utilizes X7R dielectric material for reliable performance across wide industrial temperature ranges
• Designed as a surface-mount device to optimize printed circuit board real estate

Applications

• Power supply input stages requiring combined filtering and surge protection
• Electronic circuits needing inrush current limiting without discrete resistors
• Electromagnetic interference suppression in high-density mounting environments
• General-purpose applications requiring integrated passive component functionality

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm electrical characteristics and termination materials. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Confirm that the integrated 50 mA current rating meets the design requirements for inrush suppression. Cross-reference the X7R dielectric specifications with thermal management needs in the final assembly.

Selection Notes

Select this component when design constraints require combining filtering and inrush limiting into a single surface-mount package. The 1206 form factor suits applications with limited board area. Consider the 200 VDC rating and X7R temperature stability for general electronic environments. Evaluate the 50 mA internal resistance capability against peak load currents to ensure adequate protection without excessive voltage drop during normal operation.
