- ※） The saturation current value (Idc1) is the DC current value having inductance decrease down to 30%. (at 20℃) 

- ※） The temperature rise current value（Idc2) is the DC current value having temperature increase up to 40℃. (at 20℃) 

- ※） The rated current is the DC current value that satisfies both of current value saturation current value and temperature rise current value.

METAL CORE SMD POWER INDUCTORS (MCOIL[TM] MD SERIES） 

## ■PRECAUTIONS 

|1. Circuit Design|n|
|---|---|
||◆Operating environment|
||1. The products described in this specification are intended for use in general electronic equipment,(office supply equipment,|
|Precautions|telecommunications systems, measuring equipment, and household equipment). They are not intended for use in mission-critical<br>equipment or systems requiring special quality and high reliability (traffic systems, safety equipment, aerospace systems, nuclear|
||control systems and medical equipment including life-support systems,) where product failure might result in loss of life, injury or|
||damage. For such uses, contact TAIYO YUDEN Sales Department in advance.|
|||
|2. PCB Design||
|Precautions|◆Land pattern design<br>1. Please refer to a recommended land pattern.|
||◆Land pattern design|
|Technical|Surface Mounting|
|considerations|・ Mounting and soldering conditions should be checked beforehand.|
||・ Applicable soldering process to this products is reflow soldering only.|
|||
|3. Considerations for automatic placement||
||◆Adjustment of mounting machine|
|Precautions|1. Excessive impact load should not be imposed on the products when mounting onto the PC boards.|
||2. Mounting and soldering conditions should be checked beforehand.|
|Technical|◆Adjustment of mounting machine|
|considerations|1. When installing products, care should be taken not to apply distortion stress as it may deform the products.|
|||
|4. Soldering||
||◆Reflow soldering|
||1. Please contact any of our offices for a reflow soldering, and refer to the recommended condition specified.|
||2. The product shall be used reflow soldering only.|
||3. Please do not add any stress to a product until it returns in normal temperature after reflow soldering.|
||◆Lead free soldering|
|Precautions|1. When using products with lead free soldering, we request to use them after confirming adhesion, temperature of resistance to soldering<br>heat, soldering etc sufficiently.|
||◆Recommended conditions for using a soldering iron (NR10050 Type)|
||・ Put the soldering iron on the land-pattern.|
||・ Soldering iron's temperature - Below 350℃|
||・ Duration - 3 seconds or less|
||・ The soldering iron should not directly touch the inductor.|
||◆Reflow soldering|
||1. If products are used beyond the range of the recommended conditions, heat stresses may deform the products, and consequently|
||degrade the reliability of the products.|
||・NR30/40/50/60/80, NRV20/30, NRH24/30, NRS20/40/50/60/80 Type, NR10050 Type, NS101/125 Type|
||Recommended reflow condition (Pb free solder)|
||300<br>5sec max|

|6. Handling||
|---|---|
|Precautions|◆Handling<br>1. Keep the product away from all magnets and magnetic objects.<br>◆Breakaway PC boards (splitting along perforations)<br>1. When splitting the PC board after mounting product, care should be taken not to give any stresses of deflection or twisting to the board.<br>2. Board separation should not be done manually, but by using the appropriate devices.<br>◆Mechanical considerations<br>1. Please do not give the product any excessive mechanical shocks.<br>2. Please do not add any shock and power to a product in transportation.<br>◆Pick-up pressure<br>1. Please do not push to add any pressure to a winding part. Please do not give any shock and push into a ferrite core exposure part.<br>◆Packing<br>1. Please avoid accumulation of a packing box as much as possible.<br>◆Board mounting<br>1. There shall be no pattern or via between terminals at the bottom of product.<br>2. Components which are located in peripheral of product shall not make contact with surface (top, side) of product.|
|Technical<br>considerations|◆Handling<br>1. There is a case that a characteristic varies with magnetic influence.<br>◆Breakaway PC boards (splitting along perforations)<br>1. The position of the product on PCBs shall be carefully considered to minimize the stress caused from splitting of the PCBs.<br>◆Mechanical considerations<br>1. There is a case to be damaged by a mechanical shock.<br>2. There is a case to be broken by the handling in transportation.<br>◆Pick-up pressure<br>1. Damage and a characteristic can vary with an excessive shock or stress.<br>◆Packing<br>1. If packing boxes are accumulated, that could cause a deformation on packing tapes or a damage on the products.<br>◆Board mounting<br>1. If there is pattern or via between terminals at the bottom of product, it may cause characteristics change.<br>2. If components which are located in peripheral of product make contact with surface (top, side) of product, it may cause damage or<br>characteristics change.|
