The 1120-271K-RC is a high-current choke from Bourns' 1120 Series, designed for power supply filtering and electromagnetic interference (EMI) suppression in high-current applications. It features an inductance of 270 µH at 1 kHz with a DC resistance of 0.213 O (±20%), rated for a maximum current of 2 A with a 50 °C temperature rise. The device incorporates an epoxy-coated ferrite bobbin core with VW-1 rated shrink tubing, self-leaded construction with fixed lead spacing, and a center hole for mechanical mounting. It withstands a dielectric voltage of 2500 Vrms (terminal to shrink tube cover) and 1000 Vrms (terminal to core), with an operating temperature range of -55 °C to +105 °C. This choke is ideal for switching power supplies, DC-DC converters, and noise filtering circuits where compact size and high current capacity are required.
