1206J0500472MJTE03

Overview

The Knowles Syfer 1206J0500472MJTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 1206 (3216 metric) case size with X7R dielectric characteristics, providing stable capacitance performance across varying temperatures. The component offers a nominal capacitance of 4700 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. It utilizes flexible end terminations to enhance mechanical durability against board stress. Operating within a temperature range of -55°C to +125°C, this Class 2 capacitor is engineered for robust electronic applications requiring reliable signal coupling or decoupling.

Feature Summary

• Flexible soft termination design improves resistance to mechanical stress and solder joint fatigue
• X7R dielectric material ensures stable capacitance performance over a wide operating temperature range
• High reliability construction suitable for demanding industrial and commercial environments

Applications

• Industrial control systems requiring robust passive components
• Automotive electronics meeting strict reliability standards
• Telecommunications infrastructure equipment
• General-purpose signal coupling and decoupling in high-density PCBs

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and packaging details. Ensure compatibility with automated pick-and-place equipment regarding tape and reel specifications. Cross-reference RoHS compliance status with current regulatory requirements before integration into final assemblies.

Selection Notes

Select this component when a balance of moderate capacitance and high voltage handling is required in a compact footprint. The flexible termination option is critical for applications subject to thermal cycling or mechanical vibration. Consider the X7R dielectric's higher permittivity compared to C0G/NP0 types for cost-effective bulk capacitance needs where tight stability is not paramount.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC family, known for stringent quality controls and extended lifecycle support. The 1206J series specifically targets applications needing enhanced mechanical integrity through specialized termination technologies. These capacitors are widely utilized in sectors where failure rates must be minimized and long-term availability is essential for production continuity.

Replacement Considerations

Direct substitutes include other 1206 X7R 4700pF 50V MLCCs with flexible terminations from manufacturers such as Murata (e.g., GRM series with similar flex features) or TDK (e.g., C3225 series). Verify that any replacement maintains the same flexibility rating and voltage derating characteristics to ensure equivalent mechanical and electrical performance.
