1206J1000102MJTE03

Overview

The Knowles Syfer 1206J1000102MJTE03 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 1206 (3216 metric) case size with C0G (NP0) dielectric material, ensuring stable capacitance characteristics over varying temperatures and voltages. The component offers a nominal capacitance of 1 nF with a tolerance of ±20% (indicated by the 'M' code). It is rated for a DC voltage of 100 VDC and operates within a temperature range of -55°C to +125°C. The device utilizes a nickel barrier termination system with tin plating, providing robust solderability and reliability for high-performance electronic applications.

Procurement Notes

Verify the specific termination finish and tolerance code against the manufacturer's datasheet before procurement. Confirm that the reel packaging quantity matches production requirements. Ensure the component meets all relevant automotive or industrial qualification standards required for the target application environment.

Selection Notes

Select this component when a 1206 footprint is required with a 1 nF value and relaxed ±20% tolerance. The C0G dielectric makes it suitable for applications where capacitance stability is critical. Consider the 100 VDC rating to ensure adequate voltage headroom in the circuit design.

Part Context

This part belongs to the Knowles Syfer J-series of high-reliability MLCCs. These capacitors are engineered for demanding environments, often serving in automotive and industrial sectors where long-term stability and resistance to thermal stress are essential. The series emphasizes consistent electrical performance and mechanical durability.

Replacement Considerations

Direct substitutes must match the 1206 case size, 1 nF capacitance, 100 VDC rating, C0G dielectric, and ±20% tolerance. Verify termination compatibility if replacing with parts from different manufacturers.
