Technical Specifications

The Y8483-B has a specific inductance value, typically measured in microhenries (µH). It also has a rated current, DC resistance (DCR), and self-resonant frequency (SRF). The shielded construction minimizes electromagnetic interference (EMI). The inductor is designed to operate over a wide temperature range. Detailed specifications, including the inductance tolerance, Q factor, and saturation current, can be found in the Coilcraft datasheet.

Inductors are used in DC-DC converters to store energy during the switching cycle and release it to the output. In RF circuits, they are used for impedance matching and tuning. In EMI filtering, they block high-frequency noise from entering or leaving the circuit. The selection of an inductor depends on the application requirements, including the inductance value, current handling capability, and frequency range.
