PowerInductors–DR0810Series
These small footprint power inductors are designed for
maximum efficiency and lowest cost. They are ideal for
noise filtering in power amplifiers, power supplies and
speaker crossover networks.
This series is available in a broad range of inductance
from 3.3 to 1000 µH with 10% tolerance for all values
above 8.2 µH.
Their open construction allows current ratings up to
9.5 Amps with a mere 0.01 Ohms of resistance. They
have industry-standard pin spacing of 5 mm and a rugged
PVC sleeve to completely protect the winding.
Free evaluation samples are available by contacting
Coilcraft or ordering them on-line at www.coilcraft.com.
