Chassis mount resistors are components that are mounted on the chassis or frame of a device. They provide a durable way to attach voltage or current limiting components that need to be protected from environmental damage, or from damage due to movement. The THS503R9J is a product of this type. It is a glass-glaze resistor suitable for application in power supplies, converters, automotive electronics, and home appliances.

The THS503R9J is a three-terminal chassis mounting resistor with a resistor element mounted between a pair of insulated thermally conductive plates. It has an operating voltage rating up to 400V, a power rating of 2.2W, and a temperature coefficient of 25ppm/°C. The resistor element is composed of a core grid composed of molybdenum, tantalum, and vanadium metals, which are bonded together and electrically insulated. The thermally conductive mounting plates are constructed from alumina ceramic insulation and metalized with high-temperature solder.

The THS503R9J has a flat surface for mounting to a chassis or frame. This allows for easy and secure mounting to the chassis, eliminating the need for additional hardware. The flanged design of the resistor element allows for maximum heat transfer away from the resistor element and into the mounting plates. This optimizes the thermal performance of the THS503R9J and allows it to function in high-temperature environments.

The working principle of the THS503R9J is based on the thermal transfer of heat away from the resistor element and into the thermally conductive mounting plates. When the resistor element is in use, the heat generated is transferred away from the element and into the mounting plates. The mounting plates then dissipate this heat into the chassis or frame of the device. The thermally conductive plates are designed to minimize the thermal resistance between the resistor element and the chassis or frame. This ensures that the heat is quickly and efficiently dissipated, preventing any damage to the resistor element or device due to thermal overload.

The THS503R9J is an excellent choice for use in a wide range of applications where durability, thermal performance, and dependability are of primary importance. These applications include power supplies, converters, automotive electronics, and home appliances. It is also suitable for use in harsh industrial environments, where the chassis mount capability of the THS503R9J provides reliable protection from various environmental conditions.
