SQM700JB-0R82

Through hole resistors, such as the SQM700JB-0R82 are integral components in modern electronic circuits, required to maintain electrical signal integrity. The device works by converting incoming electrical energy into dissipated heat energy. By doing so, the resistor is able to provide a relatively constant resistance along the length of the unit, despite external forces such as temperature, pressure, and voltage.

The SQM700JB-0R82 is a vertical through-hole mounted resistor capable of handling up to 450V DC. It is available in several resistance values, ranging from 0.25Ω to 5Ω. The resistor is constructed mainly from ceramic, and has a low positive coefficient of resistance (TCR). This ensures that the resistance value remains constant over a wide range of temperatures, ideal for systems that may be subjected to severe temperature fluctuations.

The primary application of the SQM700JB-0R82 is in linear power supplies and automotive electronics. In both of these fields, a constant resistance value is necessary to control the flow of electrical current. The device\'s high insulation resistance (measured at around 1000MΩ) ensures that the signal current is not affected by ambient noise. Furthermore, its high power rating of up to 0.50W allows it to be integrated into high-power systems, meaning that a single device can provide a significant voltage drop across a circuit without having to resort to combining multiple resistors in parallel.

The physical design of the SQM700JB-0R82 ensures that, when it is installed, it remains in a fixed position with respect to the printed circuit board. This helps to maintain the device\'s resistance value, and reduce the possibility of a loose connection. The high-grade insulation material used in the construction of the resistor also aids in its durability and performance, making it an invaluable asset in the power supply and automotive industries.

Overall, the SQM700JB-0R82 is an extremely dependable and reliable through-hole resistor, capable of securely handling up to 450V DC. Its high thermal and electrical resistance ratings, combined with its low coefficient of resistance, make it an excellent choice for power supplies and automotive electronics applications.
