Low resistance values Wire resistors for precise measurements in electronics

Wirewound resistors are essential components in electronics that are used to regulate the flow of current in a circuit. They consist of a thin wire wound around a core and offer high precision and stability, even under extreme conditions. These resistors are particularly in demand in applications where high performance and durability are required.
