SM Series Amorphous Choke Coils
The SM series amorphous choke coils are designed for noise suppression in power supplies and automotive electronic components. They feature a lead-wire through-core structure for low DC resistance and utilize an iron-based amorphous core for excellent high-temperature operational stability. These coils are suitable for automotive applications and offer high safety and reliability due to very small leakage flux in the absence of inter-winding short circuits.
