Specifications and Features
The MS Series ceramic resistors are designed with good heat durability, low temperature coefficient, low noise, high load power, and high insulating capacity. They operate within an ambient temperature range of -55℃ to +275℃.

Dimensions and Ratings
The resistors are available in various power ratings: 5W, 10W, 15W, and 20W. Resistance tolerance options include ±1%, ±2%, ±5%, and ±10%. Resistance values range from 0.1Ω to 10KΩ. The dimensions vary based on the power rating, with specific measurements provided for length, width, height, and other parameters.

Ordering Information
The ordering code is structured as follows: Series Name (MS), Power Rating (e.g., 10 for 10W), Resistance Tolerance (e.g., J for ±5%), and Resistance Value (e.g., 10R00 for 10Ω).

Performance and Testing
The resistors are tested according to JIS C 5201-1 standards. Key performance tests include temperature coefficient, short time overload, load life in humidity, temperature cycle, resistance to soldering heat, solderability, and nonflammability. The resistors demonstrate a temperature coefficient of ±300ppm/℃ and various resistance change rates under different conditions.

Derating Curve
The derating curve illustrates the relationship between ambient temperature and rated power, indicating how power capacity decreases with increasing temperature.
