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.
