Thick Film Resistor Noise
Depending on the application the noise generated when current flows through a thick film resistor can cause serious system errors. In this post, we consider the source of resistor noise and how it can be minimised. What Is Electrical Noise Electrical noise is an...
Network resistor Application Limitations
Network resistors are used in a wide range of applications from relatively simple pull up/pull- down resistors and terminating resistors to matched resistors. In some applications, resistors with a variety of resistance values may be incorporated on the same...
What Causes A Thick Film Resistor To Degrade Over Time?
There are many environmental and electrical factors that can cause the performance of a thick film resistor to degrade over time. To avoid compromising system performance it is important to be aware of the issues and to manage them appropriately. Resistors are used in...
High Voltage Resistors In Voltage Divider Applications
The purpose of a voltage divider is to convert a high voltage into a related low voltage. The basic voltage divider circuit consists of two resistors connected in series. With the input voltage (high) connected across the resistor terminals, the output (low) voltage...
Choosing A High Power Resistor Heatsink
The purpose of a high power resistor heatsink is to keep the temperature of the resistor element below its maximum operating temperature but choosing the right heatsink can be a difficult process. Heatsinks are generally chosen to match the precise requirements of a...
