## RLF Series RLF12545
This inductor is designed for power circuits that require a low profile, low inductance, and large current, such as those used in notebook PCs. It measures L12.5 × W12.8 × T4.5mm, about 40% lower in profile than our existing products (the SLF12575 type).
## **PRODUCT IDENTIFICATION**
RLF 12545 T- 2R7 N 8R7 - PF (1) (2) (3) (4) (5) (6) (7)
- (1) Series name
## **FEATURES**
- With the height at only 4.5mm, and retaining the DC current superimposition characteristic, this inductor reduces DC resistance 20 to 50% lower than our existing products(the SLF12575 type).
- Structural efficiency allows for both a lower profile than, and electrical features equivalent to, our existing devices.
- The low profile makes the inductor particularly optimal for power circuit applications requiring low voltages and large current.
- Completely lead free for both inside of products and terminal electrodes.

RLF 12560 T- 1R0 N 140 (1) (2) (3) (4) (5) (6)
## **FEATURES**
- Comparing with existing products(RLF12545), DC current superimposition characteristic has improved. Especially, inductance rises about 10% in spite of high temperature at 100°C. In addition, inductance has risen about 30% at normal temperature.
- Using flat-square wire for winding, that is rising space factor, these inductors can reduce current resistance and suppress calorific value.
- Forming internal gap, their structure suppress outgoing magnetic flux leakage.
- Completely Pb free for both inside of products and terminal electrodes.
