What is BS EN 60195 - Method of measurement of current noise generated in fixed resistors about?
BS EN 60195 is an international standard that discusses the method of measurement of current noise generated in fixed resistors.
BS EN 60195 specifies a method of measurement and associated test conditions to assess the "noisiness", or magnitude of current noise, generated in fixed resistors of any given type. The method applies to all classes of fixed resistors.
Note: The method described in this International Standard is not a general specification requirement and therefore is applied if prescribed by a relevant component specification, or if agreed between a customer and a manufacturer.
Who is BS EN 60195 - Method of measurement of current noise generated in fixed resistors for?
BS EN 60195 on the method of measurement of current noise generated in fixed resistors is useful for:
- Electronics and Telecommunication engineers
- Telecommunications and electronics device manufacturers
- Communication engineers
- Telecom engineers
- Telecommunication network engineers
Why should you use BS EN 60195 - Method of measurement of current noise generated in fixed resistors?
Noise is a generic term for voltage or current changes that are typically random, have small amplitude, and are always unwanted. Noise is an unwanted phenomenon for resistors.
The aim is to provide comparable results for the determination of the suitability of resistors for use in electronic circuits having critical noise requirements.
BS EN 60195 provides guidance on the method of measurement, measurement system requirements, verification of the measuring system to verify the performance of the measurement system by checking the level of system noise, including thermal noise, without involving any specimen.
The temperature, relative humidity, and atmospheric pressure test recommended by BS EN 60195 are implemented to ensure or verify the ability to maintain the service life if the specimen is prescribed other ambient conditions for this measurement.
Precautions are mentioned in BS EN 60195 to serve as a guide in selecting suitable locations. As a result, BS EN 60195 assists you in determining the accuracy of the present noise determination deteriorates as the total noise approaches the system noise. This provides high stability, a broad working range, minimal noise, and a low cost.
