They are critical in filtering, energy storage, and noise suppression in power electronic systems. They are designed to handle higher currents and are optimized for minimal power loss and thermal efficiency. ## **Benefits** 1. Automotive grade available 2. Energy Storage, Efficiently stores and transfers energy in DC-DC converters and power supplies. 3. High Current Handling, Supports high current capacity with minimal losses, ensuring thermal stability. 4. Compact and Efficient Design, Advanced materials and construction enable miniaturization without sacrificing performance, ideal for space-constrained designs. ## **Applications** 1. Automotive Systems for ADAS, infotainment. 2. Industrial Equipment: Robotics, power tools, industrial automation, and IoT devices. 3. DC-DC converters, inverters, and battery management systems. 4. Base stations, 5G infrastructure, and signal processing systems. 5. Consumer Electronics: Smartphones, laptops, tablets, wearable devices, and gaming consoles. ## **Product Information** |**Series**|**L (mm)**|**W(mm)**|**T (mm)**|**Inductance (**µ**H)**| |---|---|---|---|---| |AMRU|4.2|4.7|1.2|0.22 ~ 47| ||4.2|4.7|1.8|| ||6.8|7.3|2.8|| ||10.2|11.6|3.8|| ||12.8|13.8|6.5|| ## **AMRU00040412 Series Specification** ## AEC-Q200 **==> picture [435 x 426] intentionally omitted <==** **----- Start of picture text -----**

Operating temperature range -40°C to 125°C. 2. Isat for Inductance drop 30% from its value without current. 3. Irms for a 40°C temperature rise from 25°C ambient. 4. The part temperature (ambient + temp rise) should not exceed 125°C under worst case operating conditions. Circuit design 125°C under worst case operating conditions. Component placement, PCB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application. 5. Absolute maximum voltage 30V DC. (Based on test method, it may not the sameunder different application, it is recommended to verify first.) ## **AMRU00040412 Series Specification** AEC-Q200 ~~EC~~ 8 **AMRU00040412 Series 8.1 Construction** **==> picture [68 x 80] intentionally omitted <==** **----- Start of picture text -----**
