1206Y1000472MJTE03

Overview

The Knowles Syfer 1206Y1000472MJTE03 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a C0G (NP0) dielectric material, ensuring stable capacitance characteristics across varying temperatures and voltages. The component has a nominal capacitance of 4700 pF with a tolerance of ±20%. It is rated for a DC voltage of 100 VDC and utilizes a 1206 (3216 metric) case size. The termination system incorporates a nickel barrier structure to enhance solderability and reliability during assembly processes.

Feature Summary

• Utilizes C0G (NP0) dielectric for high stability and low loss in RF applications
• Features a flexible termination design to improve resistance to mechanical stress
• Incorporates a nickel barrier layer to ensure robust solder joint integrity

Applications

• High-frequency RF circuits requiring stable capacitance
• Precision timing and oscillator circuits
• General-purpose decoupling in sensitive analog signal paths

Procurement Notes

Verify the specific suffix 'MJTE03' against official manufacturer documentation to confirm packaging details and terminal specifications. Ensure compatibility with automated pick-and-place equipment regarding the reel format. Cross-reference the part number with the latest RoHS compliance declarations to meet regional regulatory requirements for electronic assemblies.

Selection Notes

Select this component when a 1206 footprint is required with a 100V rating and 4700pF value. The C0G dielectric is essential for applications where capacitance drift must be minimized. Consider the nickel barrier termination if lead-free soldering processes are mandated or if enhanced corrosion resistance is needed for the solder joints.

Part Context

This part belongs to the Knowles Syfer general-purpose MLCC line, characterized by high reliability and consistent performance. The Y-series designation typically indicates specific termination and packaging variations within the broader 1206 family. These capacitors are engineered for demanding environments where standard commercial-grade components may not suffice due to thermal or mechanical constraints.

Replacement Considerations

Direct substitutes include other manufacturers' 1206 C0G capacitors with identical 100V and 4700pF ratings. Verify that replacement parts offer compatible termination metallurgy and similar flexural strength ratings to maintain board reliability.
