Chassis Mount Resistors (CMR) are a type of fixed resistors used in a variety of circuits. The resistor is designed to mount to any type of panel or chassis, allowing for a secure installation. TE2500B27RJ is a CMR solution designed for applications requiring an optimal combination of performance, space and cost effectiveness.

The TE2500B27RJ is a surface-mount power resistor that offers high dissipation in the limited space of a chassis mount. It has a 12-pin design, with two power connections for the resistive element and a third for the external heat sink. The body is constructed of a thermally conductive, heat-resistant ceramic substrate. The resistor also features a tight tolerance of ±1% on its rated value of 25Ω. It is capable of operating up to a maximum of 25W in air.

The resistors in the TE2500B27RJ are manufactured using a process called “ion implantation” which offers superior performance over traditional methods of producing resistors. This process utilizes ionized particles that are injected into a substrate material, forming the resistive layer of the resistor. This process creates more uniform resistivity and improved thermal conductivity compared to other methods.

In addition to the high-density resistive element, the TE2500B27RJ also features an integrated heat sink made of alumina ceramics. This heat sink dissipates the heat generated by the resistor, providing excellent thermal performance. The heat sink is designed to mount directly to any chassis, allowing for minimal installation effort.

The TE2500B27RJ is an ideal solution for applications requiring a high-performance resistor that can be easily installed in a chassis-mount configuration. It is suitable for use in a wide range of industries including automotive, telecommunications, consumer electronics, and audio/video equipment. Its high dissipation and tight tolerance make it perfect for a variety of circuits, where power and accuracy are critical.

The working principle of the TE2500B27RJ is simple. When a current passes through the resistor, it causes it to generate heat. The heat is then dissipated through the heat sink, keeping the resistor at a safe operating temperature. The resistor also adjusts its resistance according to the changing current passing through it, ensuring that the circuit behavior remains stable and consistent.

In conclusion, the TE2500B27RJ is an excellent solution for applications requiring a reliable, power-controlled resistor. Its 12-pin design, heat-resistant ceramic substrate, and integrated heat sink make it ideal for chassis mount applications. It is capable of operating up to a maximum of 25W in air and offers superior performance and space-savings. The TE2500B27RJ is a practical and cost-effective solution for a variety of circuits.
