Murata Power Solutions Flat Coil SM Power Inductor

Murata Power Solutions Flat Coil SM Power Inductors

The 3700, 3800, and 3900 Series from Murata Power Solutions are Flat Coil Surface Mount Power Inductors designed for high current, low loss applications. The power inductors provide a wide range of inductance values from 0.15 tp 10µH with DC ratings up to 19.5A. Extremely small sizes offer space savings, with the smallest part measuring just 14.5 x 11.5 x 5.8mm (0.571 x 0.453 x 0.228 inches). With DC resistance values ranging from 0.9 to 20.3mOhm, voltage drop is kept to an absolute minimum. Typical applications for the Murata Power Solutions Flat Coil SM Power Inductors include voltage regulator modules, notebook computers, plasma displays, and other dc-dc power conversion applications where a high transient response is needed. The operating temperature range of -40 to +130ºC make these inductors suitable for many environments.

1 The maximum DC Current is the value at which the inductance falls to 65% (tolerance ±30%) or 75%
(tolerance: ±20%) of its nominal value or until its temperature rise reaches 40°C, whichever is sooner.
2 The saturation current is the continuous current at 20°C ambient at which the inductance falls to 65% (tolerance:
±30%) or 75% (tolerance: ±20%) of its nominal value.
