Electrification Solutions

Bourns Electrification Solutions feature a comprehensive range of transformers, chokes, diodes, resistors, fuses, transistors, and varistors. These products are designed for systems used in the process of electrification, which is the transition from traditional sources of energy, such as oil and gas, to cleaner and more sustainable forms of energy. Electrification affects how cars are refueled, homes are heated, and industries are powered, with the end goal being a reduction in air pollution and energy waste. One example is a heat pump, which is up to 3x more efficient than a boiler to save on heating bills.
