B-20L-25, Ферритовый сердечник, цилиндрический, 300МГц, длина 1.2мм, внутренний 1мм, внешний 2.5мм

The B-20L-25 is a Bead Core suitable for use on round cable. The EMI cores are part of a family of passive components which address the issues of noise or electromagnetic interference (EMI) in circuits or systems. When the desired performance of an EMI core cannot be obtained with a single pass through the core, the impedance characteristics can be changed with multiple turns. A turn is counted by the number of lead-wire windings which pass through the inner hole of the core. Adding turns will result in higher impedance while also lowering the effective frequency range.

• Solid construction
• Windings on the outside of the core do not count
