The LR1F140K also features power ratings of 0.6W, 1W, 2W, 3W, and 6W, with resistance values from 1.0 ohms to 1000K ohms. Moreover, the device can withstand extreme temperatures of -55°C to +155°C and high-temperature reflow cycles from 350°C to 370°C.

Working Principle of the LR1F140K

The LR1F140K resistor works on a temperature-compensated principle. This type of resistor structure uses an insulated coil material as the base element for providing resistance. The coil is formed by heating and stretching a heat treated nickel alloy orInflexible metal alloy, then by impregnating it with an insulating material such as ceramic powder or fibreglass, and then encasing it with a mouldable material that provides insulation and protect the coil from external environment. Once the coil is formed, the resistor is placed inside a temperature-controlled environment to maintain it in a given temperature range. A temperature sensing element like a thermistor is attached to the resistor to measure the temperature of the resistor. An electrical current is then passed through the resistor to heat up the coil and the thermistor senses the temperature of the resistor. If the temperature of the resistor is above the specific range, the thermistor cuts off the current to prevent the resistor from getting heated more than the specific temperature.Once the desired temperature is reached, the thermistor allows the current to flow again and the heat generated by the current dissipates into the environment. This reduces the temperature of the coil and the thermistor again senses it when the temperature reaches below the prescribed temperature. The entire process creates a temperature compensated, self-regulating and self-stabilizing resistor. The LR1F140K does not require any additional thermal control components, and provides outstanding long-term stability and reliability.
