It is commonly used in power supply designs, rectifiers, voltage regulators, and current control circuits. It is also frequently used as a feedback element in current-sensing circuits, such as those found in SCR applications. Additionally, the SP1879-1K13B is used in various audio applications, such as in speaker/tweeters, speaker protection circuits and preamplifiers.

Working Principle:

The SP1879-1K13B works on a simple principle—when a voltage is applied across its leads, it generates heat and this heat dissipates in the form of conduction and radiation. This heat, in turn, causes a change in resistance, which is measured as ohms. The precise resistance value of the SP1879-1K13B resistor varies from part to part, which is why this type of resistor is favored for applications that require very specific resistance values. The tolerance of the part\'s resistance can also be as low as 5%, ensuring that it provides consistent performance with minimal variation.

The SP1879-1K13B is a popular choice in power handling applications because it can handle higher peak power levels than standard carbon film and wirewound resistors. Additionally, this type of resistor is less prone to self-heating and thermal runaway problems, reducing the risk of component failure. It can also be used in both DC and AC circuits with operating frequencies up to 1MHz.

Conclusion:

The SP1879-1K13B is a through hole resistor, which is widely used in a variety of applications such as consumer, industrial and power electronics. Its tolerance of 5% makes it ideal for applications that require very specific resistance values. Additionally, the resistor can handle higher peak power levels than standard carbon film and wirewound resistors and is less prone to self-heating and thermal runaway problems. It can be used in both DC and AC circuits with operating frequencies up to 1MHz.
