## **Power Inductor** 

## **BWMR Series** 

## **Overview** 

BWMR series are metal alloy wirewound power inductors. Its rated current could be increased up to 35% compare to ferrite base power inductor. 

## **Benefits** 

1. Constructure Low RDC and high rated current 

2. Wide inductance range 

3. Shielded and miniature package design 

## **Applications** 

1. Smartphones, tablets and wearable devices 

2. DSC, camcorders 

3. DC/DC converters

**Note:** □ -tolerance   M=±20% / T=±30% 

1.Operating temperature range -40 ℃ ~125 ℃ (Including self - temperature rise) 

2.Isat for Inductance drop 30% from its value without current. 

- 3.Irms for a 40 ℃ temperature rise from 25 ℃ 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, PWB 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 25VDC
