5900-123 Description

Short technical summary and product information.

The Bourns 5900-123 is a fixed inductor from the 5900 series, designed for high current RF choke applications. It features a ferrite drum core with wirewound construction, providing an inductance of 12 mH with ±10% tolerance. The inductor is unshielded and rated for a nominal current of 220 mA (with a saturation current of 241 mA at 10% inductance drop and a temperature rise current of 200 mA). Maximum DC resistance is 8.5 Ohms.

 

The component is housed in an axial through-hole package measuring 0.453 inches in diameter by 0.900 inches in length (11.51 mm x 22.86 mm). It is rated for dielectric strength of 2500 V RMS and operates over a temperature range of -55°C to +105°C. The 5900 series inductors are known for high current capacity and low DCR, with VW-1 rated shrink tubing covering the winding.

 

This inductor is suitable for use in power supply filtering, DC-DC converters, and other applications requiring a stable inductance at moderate current levels. The ferrite core material provides excellent performance at frequencies up to 1 kHz (test frequency). The part is RoHS compliant and REACH unaffected, with an MSL of 1 (unlimited).
