TOKEN BWL Low Resistive Power Resistors Low Resistance Power Resistors Lowest Ohmic Value Resistor (BWL) Minimise Power Consumption Preview In response to demand for more energy efficient products, Token Electronics has expanded its current sensing resistors offering with the launch of the BWL series, its lowest ohmic value resistor, to minimise power consumption. The BWL series has been designed for current sensing in power electronic systems and the resistors are available in 0.5W to 10W power ratings, with a wide ohmic range starting from as low as 0.005Ω. Products in the economical, low-inductance BWL series are axial leads with high temperature mold compound, making them well-suited to the industry trend and are ideal for all types of current sensing applications including switching and linear power supplies, instruments and power amplifiers In addition, the BWL series utilizes metal strip technology, essential for those involved in constructing devices and circuits for the detection of currents. Token’s BWL standard series is lead-free and RoHS compliant and can be a replacement for Vishay, IRC, KAO, Panasonic current sense devices with more competitive price and short lead time.
