Technical Specifications

The SSL0810T-121M-S has an inductance value of 120μH (121 = 12 x 10^1). The 'M' in the part number indicates the inductance tolerance, typically ±20%. The saturation current is a key parameter, representing the DC current at which the inductance drops significantly (usually by 10% or 20%). Consult the datasheet for the precise saturation current and RMS current ratings. The operating temperature range is also an important specification, usually spanning -40°C to +125°C, allowing for use in harsh environments. The 'S' at the end of the part number typically signifies a specific packaging type, such as tape and reel, suitable for automated assembly processes. The shielded construction employs a ferrite core to contain the magnetic field and minimize EMI emissions.

This inductor is frequently used in step-down (buck) converters to efficiently convert a higher voltage to a lower voltage. It stores energy during the switch-on time and releases it during the switch-off time, providing a stable and regulated output voltage. It is also found in boost converters, which step up a lower voltage to a higher voltage. The shielded construction is particularly important in applications where minimizing noise is critical, such as in audio circuits or sensitive measurement equipment.
