Additional Details

The TSL1112S-221K1R0-PF features an inductance of 220μH and a rated current of 1.0A. The DC resistance is typically low, contributing to efficient power transfer. It is designed for surface-mount technology (SMT). The operating temperature range typically spans from -40°C to +125°C. The shielded construction uses a magnetic material to confine the magnetic field, minimizing radiated emissions. This is essential for sensitive electronic devices. The inductor's compact size and high current capability make it suitable for space-constrained applications. Optimal PCB layout is crucial; place the inductor close to the switching IC and utilize wide traces to minimize resistance. The saturation current is the current level where the inductance value drops by a predefined percentage (e.g., 20%).
