Chassis mount resistors are used to provide a safe, reliable and easy resistance value in a wide range of applications. The HSA252K7J is an example of such a chassis mount resistor. It is designed to provide resistance value accuracy with minimum noise, and maximum dissipation of excess power. This makes it suitable for a variety of applications, from audio and audio/video systems to motor and locomotive control.

The HSA252K7J chassis mount resistor is able to provide resistance value accuracy over a wide temperature range. Its resistance tolerance rating is +/- 0.5%, meaning that it will maintain its specified value over temperatures ranging from -25ºC to + 85ºC. Moreover, its operating temperature range is from -55ºC to 125ºC, which allows it to be used in many industries and applications where temperature fluctuation is common.

The HSA252K7J is constructed using an electrolytic capacitor and a resistor die, providing high-performance in power dissipation, in comparison to other chassis mount resistors. Its maximum power dissipation is 3 watts (W), with a rated voltage of 6.3V and an operating voltage range of 0.25-6.3V. This makes it suitable for AC and DC applications, where the peak voltage is 6.3V or less.

In terms of noise, the HSA252K7J provides the best-in-class performance, with a maximum current noise rating of just 0.1 millivolt (mV). This low noise rating provides increased accuracy and stability for audio applications, providing a clear sound and uninterrupted signal. In addition, it has a wide frequency range of 0.1 to 10MHz, making it a suitable choice for modern audio and video equipment.

The HSA252K7J is available in various package sizes, from a small 0805 SMD (Surface Mount Device) package to a more bulkier 2.2 inch by 1.2 inch axial case. As for operating temperature, it is typically specified as -55ºC to 125ºC for normal operation, depending on the exact package.

The HSA252K7J chassis mount resistor is a reliable and safe way to provide resistance value accuracy in many applications. Its low noise rating and wide frequency range ensure that it is well suited for audio and video purposes, whilst its wide temperature range and maximum power dissipation make it an ideal choice for motor and locomotive control.

It is important to note that this resistor should not be used without the protection of a heatsink. The temperature range of the resistor can be greatly impacted without the use of a heatsink, leading to physical damage which could cause the resistor to become non-functional.
