Additional Details

The SRR12-LAB1 features a ferrite core material to achieve high inductance values. It is typically surface mountable and reflow solder compatible. Key specifications include inductance value (in microhenries), saturation current (the current at which the inductance drops to a certain percentage of its initial value), and DC resistance. The operating temperature range is also a critical factor, ensuring reliable performance across various environmental conditions. The “LAB1” likely denotes specific electrical characteristics and packaging information within the SRR12 series. Its semi-shielded construction aids in managing electromagnetic interference without the added cost of fully shielded inductors. The specific inductance value and other parameters will be detailed in the product datasheet from Bourns.
