Document 275-1 Power Inductors–DR0608Series 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 7.5 Amps with a mere 0.012 Ohms of resistance. They have industry-standard pin spacing of 3.5 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.
