The Bourns 9250 series shielded molded RF chokes are designed for applications requiring low radiation and high reliability. These chokes feature a ferrite magnetic shield, injection molded construction for environmental protection, a flame retardant coating, and consistent body dimensions. They are ideal for use in power supplies, filters, and other circuits where EMI suppression is critical. The series offers a wide range of inductance values to meet diverse design requirements. J.W. Miller recommends using the 9250A series as a replacement for the 9250 series.
