Inductors for Power Circuits
Wound/STD • Magnetic Shielded
RLF Series RLF12545
This inductor is designed for power circuits that require a low pro-
file, low inductance, and large current, such as those used in note-
book PCs. It measures L12.5×W12.8×T4.5mm, about 40% lower in
profile than our existing products (the SLF12575 type).
FEATURES
• With the height at only 4.5mm, and retaining the DC current
superimposition characteristic, this inductor reduces DC resis-
tance 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.
APPLICATIONS
• Choke coils in power circuit of note book computers, LCD, DVD,
STB, PDP, amusement equipment, etc.

Inductors for Power Circuits
Wound/STD • Magnetic Shielded
RLF Series RLF12560
Accompanying large current power supplies, these inductors have
secured efficient characteristics by improving its magnetic circuit
based on existing products. These products meet resistance
reducing and current enlargement.
FEATURES
• Comparing with existing products(RLF12545), DC current
superimposition characteristic has improved. Especially, induc-
tance rises about 10% in spite of high temperature at 100°C.
In addition, inductance has risen about 30% at normal tempera-
ture.
• Using flat-square wire for winding, that is rising space factor,
these inductors can reduce current resistance and suppress cal-
orific value.
• Forming internal gap, their structure suppress outgoing mag-
netic flux leakage.
• Completely Pb free for both inside of products and terminal elec-
trodes.
APPLICATIONS
• Choke coils in power circuit of note book computers, LCD, DVD,
STB, PDP, amusement equipment, etc.
