Pulse Engineering Inc. (San Diego, CA) introduced its new PG0200.XXX power cube inductors, a series of low-profile, high-power-density inductors mainly used for desktop PCs with T-socket processors. Applications include servers, multi-phase voltage regulator modules (VRMs), dc-dc converters and other point-of-load applications.
The new inductors have a high power density of 426 µJ/cm³ in a 16 mm x 13.2 mm x 9.2 mm maximum profile. The inductors use a shielded E-core package, allowing heat dissipation and electromagnetic interference (EMI) shielding. The PG0200 inductors have lower direct current resistance (DCR) than toroidal inductor packages. The inductors have a high current saturation capability up to 60 A. A low DCR from 0.60 milliohms to 3.00 milliohms maximum, and tighter open-circuit inductance values from 0.22 µH to 1.8 µH with tolerances of ±15% provide efficiency and fast transient response. The inductors have rated currents from 19 A to 45 A, and an operating temperature range from -40 °C to +125 °C.
Parts in the new series are available in trays, with prices averaging $0.25 per unit for quantities above 100,000 units. Individual part pricing may vary due to volume, configuration and shipping destination. Contact Pulse directly for volume pricing and samples. Parts are available for immediate delivery.
