SUMIDA has developed a high current inductor CDB78D73B, like other products in the CDB series, CDB78D73B is in magnetic shielded surface mount structure. Featured by low loss ferrite core material and low tolerance DCR, high efficiency can be achieved.
- Ferrite core construction
- Magnetically shielded
- Operational Temperature range: -40°C ～ +125°C (including self-heating)
Multi-phase and Vcore regulators; voltage Regulator Modules (VRMs), such as server and desktop; Central Processing Unit(CPU); Graphics Processing Unit (GPU), Application Specific Integrated Circuit(ASIC); high power density; data networking density; graphics cards and battery power systems.

※1 Measuring conditions Inductance at 1MHz.
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 20% lower than its initial value.
※3 Temperature rise current: The value of D.C. current when temperature of coil increased △T=40℃ (Ta＝20℃).
