14uH PQ50 DIP Power Inductor Voltage Across Inductor In Rl Circuit

PQ50 DIP Power Inductor Manufacturer Customized DW3158


Toroidal Inductors provide a number of advantages over other inductor varieties, which include:
Compact Size — The smaller size of Toroidal Inductors allows for excellent efficiency while maintaining top level performance.Lower Cost — With smaller sizes that use less raw materials, Toroidal Inductors are a highly economical choice.
Efficient Design — Inductor designers can achieve shorter length of turn with smaller-sized Toroidal Inductors using less cooper wire and with no bobbin as with E-core designs.
