Chassis Mount Resistors: TE80B10RJ Application Field and Working Principle

Chassis mount resistors are components that allow a variable electrical resistance to be built into a circuit. They act as a protective devices, helping to prevent electromagnetic interference and overvoltage damage from occurring to the other components. The TE80B10RJ is a high-power, high-voltage, non-resettable, non-polarized, surface mount resistor with a maximum power rating of 10 watts and maximum repetitive peak voltage of 830 volts.

These resistors are frequently used in voltage regulators to help reduce current and allow for proper operation of other electrical components. Also, they are used for sensing current in circuits and for temperature Compensation. The TE80B10RJ is ideal for applications that require high power ratings, such as in harsh environments or when high currents require the use of an oversized resistor.

The TE80B10RJ offer a wide range of resistance values and power ratings and can be used to regulate current in both AC and DC applications. When installed correctly, it is capable of dissipating up to 10 watts of power without creating an excessive amount of heat. The dissipation coefficient, referred to as ‘thermal resistance’, is the total heat generated when the resistor is in use and indicates how quickly the resistor’s temperature will rise with increased current flow. For the TE80B10RJ, its thermal resistance is 1.5°C/W.

The TE80B10RJ has two types of lead configurations: surface mount or right angle. The surface mount configuration has the leads soldered to the substrate using a soldering machine; while the right angle configuration accommodates both soldering or leaded mounting and has two pins on the reverse side of the resistor for connecting to a circuit board.

Furthermore, the TE80B10RJ is characterized by its wide ‘working range’ which ensures that it operates correctly over a wide temperature range. The normal operating temperature range for this resistor is between –55°C and + 150°C. It is also equipped with a temperature coefficient of resistance (TCR) that helps to protect the resistor from damage due to thermal expansion. The TCR defines how much the resistor’s resistance changes as the temperature increases or decreases. The TE80B10RJ has a TCR of 0.096%/°C.

The TE80B10RJ is also capable of handling transient voltage surges and reverse voltage polarity. These resistors are designed to resist short-term excessive voltage and current levels that would otherwise damage unprotected resistors. They will also absorb and dissipate an energy pulse (in the form of heat) up to its maximum rating. The TE80B10RJ comes complete with a ceramic body for strong insulation and secure connection. It is also designed with heat-dissipating channels incorporated into its construction for optimum thermal performance.

The TE80B10RJ can be conveniently placed almost anywhere on a circuit board to accommodate high-voltage, high-power semiconductor applications. It is also an economical alternative to bulky variable resistors and is available in a range of packages and resistance configurations.

In conclusion, the TE80B10RJ is an ideal choice for applications requiring high power ratings and wide temperature ranges. Its thermal resistance, TCR, reverse voltage polarity and transient voltage surge capability make it a reliable and valuable resistor in a variety of circuits. Its ceramic construction ensures secure insulation and efficient thermal performance.
