Bourns 1140 Series High Current Chokes
Bourns 1140 Series High Current Chokes feature very high current capacity and low Direct Current Resistance (DCR). These chokes offer a dielectric withstanding voltage of 2500Vrms from the terminal to the shrink tube cover and 1000Vrms from the terminal to the core. The 1140 high current chokes are self-leaded with fixed lead spacing and integrated with a center hole for mechanical mounting. These chokes operate from -55°C to 105°C temperature range.
