Technical Specifications

The SSL0804T-3R3M-S features an inductance of 3.3μH. The 'M' in the part number indicates a tolerance of ±20%. It is crucial to refer to the datasheet for the specific saturation current, which dictates the current level at which the inductance starts to drop significantly. The RMS current rating specifies the maximum continuous current the inductor can handle without overheating. The operating temperature range generally extends from -40°C to +125°C. The 'S' suffix denotes the packaging, typically tape and reel for automated assembly. The shielded construction is achieved through a magnetic core material that surrounds the coil, preventing the radiation of electromagnetic fields.

This inductor is often employed in buck converters to convert a higher voltage to a lower voltage with high efficiency. The inductor stores energy during the on-time of the switching element and releases it during the off-time, smoothing the output voltage. It is also suitable for boost converters and SEPIC converters. The low EMI characteristics make it ideal for applications where electromagnetic compatibility is critical, such as in automotive electronics or medical devices.
