Flat Wire Power Inductor ForMaxim
MAX5051 Controller IC
Designed specifically for Maxim’s MAX5051 Power Supply
Controller, the A9860-B offers unmatched electrical perfor-
mance in an extremely robust, space saving package.
With its flat wire windings, this inductor has extremely low DC
resistance and offers very high saturation current ratings.
The flat core provides exceptional heat dissipation.

1. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-D fixture in an Agilent/HP 4284A impedance analyzer.
2. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
3. DC current at which the inductance drops 10% (typ) from its value
without current.
4. Average current for a 45°C rise above 25°C ambient.
5. Electrical specifications at 25°C.
