1. To order parts packaged in optional fanfold tape (800 parts per box), add the
letter “F” at the end of the part number, e.g. DR0810-824LF
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR-
meter or equivalent.
3. SRF measured using an Agilent/HP 4191A or equilvalent.
4. DC current at which the inductance drops the specified amount from its value
without current
5. Current that causes the specified temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
• Small footprint power inductors designed for maximum efficiency
and low cost.
• Ideal for noise filtering in power amplifiers, power supplies and
speaker crossover networks.
• Inductance values from 3.3 to 1000 µH, most at 10% tolerance
• Current ratings up to 7.5 Amps with only 0.010 Ohms DCR
• Industry-standard pin spacings; protective PVC sleeve
Core material Ferrite
Terminations
RoHS compliant
tin-silver over copper
