The 5900-393-RC is a high-current choke from Bourns' 5900 Series, designed for EMI filtering and power supply applications requiring high inductance values. It features a ferrite bobbin core with an inductance of 39,000 µH (±10%) at 1 kHz, a maximum DC resistance of 31.0 O, and a self-resonant frequency of 0.14 MHz. The component is rated for a saturation current of 0.13 A and a continuous rated current of 0.12 A, with VW-1 rated shrink tubing covering the winding and a dielectric strength of 2500 Vrms. Operating over a temperature range of -40°C to +125°C, this RoHS-compliant choke is ideal for high-frequency noise suppression in power conversion circuits, telecommunications equipment, and industrial power systems where reliable EMI attenuation is essential.
