Technical Specifications

The SSL0804T-4R7M-N has an inductance value of 4.7μH. The 'M' denotes the tolerance, which is typically ±20%. Refer to the product datasheet for the specific saturation current (Isat) and RMS current (Irms) ratings. The saturation current indicates the DC current level at which the inductance drops significantly (usually by 10% or 20%). The RMS current specifies the maximum continuous current the inductor can handle without overheating. The operating temperature range usually extends from -40°C to +125°C. The 'N' at the end of the part number likely designates a specific termination or packaging type. The shielded construction is achieved through a ferrite core that encloses the coil, containing the magnetic field and reducing EMI emissions.

This inductor is typically used in step-down (buck) converters to efficiently convert a higher voltage to a lower voltage. The inductor stores energy during the switch-on period and releases it during the switch-off period, ensuring a stable and regulated output voltage. It is also applicable in boost converters, which step up a lower voltage to a higher voltage. The shielded construction is especially important in applications where minimizing noise is essential, such as in audio equipment and sensitive measurement devices. Additionally, its small size makes it suitable for portable electronic devices where space is constrained.
