Technical Specifications

The SSL0804T-2R2M-S has an inductance value of 2.2μH. The 'M' in the part number indicates the inductance tolerance, which is typically ±20%. The saturation current is a critical parameter, representing the DC current at which the inductance drops by a specified percentage (usually 10% or 20%). Consult the datasheet for the precise saturation current and RMS current ratings. The operating temperature range is also a key specification, typically extending from -40°C to +125°C, allowing for use in harsh environments. The 'S' at the end of the part number usually signifies a specific packaging type, such as tape and reel, suitable for automated assembly processes.

This inductor is commonly used in step-down (buck) converters to efficiently convert a higher voltage to a lower voltage. The inductor 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 crucial, such as in audio circuits or sensitive measurement equipment.
