San Diego, Calif. Measuring less than 10-mm high with low direct current resistance (DCR) and high saturation current, the new Pulse PG0200 power cube inductors target desktop PCs with T-socket processors. Applications include servers, multi-phase voltage regulator modules (VRMs), dc-to-dc converters, and other point-of-load applications.
The Pulse power cube inductor series has a high power density of 426 micro joules per cubic centimeter in a compact 16 x 13.2 x 9.2-mm maximum package. The inductors use a shielded E-core package, which provides excellent heat dissipation and superior electromagnetic interference (EMI) shielding, said the company, and offers lower DCR than toroidal inductor packages, which improves the overall system efficiency. These characteristics are suitable for the latest VRMs powering faster microprocessors.
Rated at 19 to 45 amps (A), the PG0200 inductors have a high current saturation capability up to 60 A. They also feature a low DCR from 0.60 to 3.00 milliohms maximum and tighter open-circuit inductance values from 0.22 to 1.8 microhenries with tolerances of ±15% that provide higher efficiency and fast transient response. The operating temperature range is -40°C to 125°C.
Available in trays, pricing for the inductors average $0.25 per unit for quantities above 100,000. Individual part pricing may vary due to volume, configuration, and shipping destination. Samples are available. For detailed technical specifications, visit www.pulseeng.com/pdf/P616.pdf
