Datasheet

## **Power Inductor** 

## **BMRB Series** 

## **Overview** 

BMRx series is designed for low profile type with low RDC and ultra large current. Its molded magnetic shielded type is suitable for high-density mounting and ultra low buzz noise. Soldering conditions can be easily confirmed when mounting onto the board. 

This series also provides customers with embossed carrier type packaging for automatic mounting machine. 

## **Benefits** 

1. High rated current 

2. Ultra low buzz noise 

## **Applications** 

1. DC-DC converters 

2. Switchs and servers 

3. DC-DC converters, inverters, and battery management systems. 

4. Base stations, 5G infrastructure 

5. Consumer Electronics: Smartphones, laptops, tablets, wearable devices, and gaming consoles.

## **Note:** 

1. Operating temperature range -55°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.)
