LMax SMD Power Inductor
LMMN Series – Miniature Style M
FEATURES
• The miniature chip inductors is wound on a special ferrite core.
• 0302/ 03A2/ 0403 are high Q value at high frequency and low
DC resistance.
• 03A2/ 0403/ 0605 are low DC resistance, high current
capacity, and high impedance characteristics. They are
excellent for using as a choke coil in DC power supply circuits.
CHARACTERISTICS FOR
LWI0I/LWI02/LWI03/LWI04
• Rated DC Current (Isat): The current when the inductance
becomes 30% typical its initial value (Ta=25°C)
• TemperatureRise Current(I rms): The actual currentwhen the
temperature of coil becomes A T=40°C (Ta=25°C)
• Operating temperature range: -40
~
105°C
APPLICATIONS
• Pagers, Cordless Phone
• High Frequency Communication Products
• Personal Computers
• Disk Drives And Computer Peripherals
• DC Power Supply Circuits

• Rated DC Current: The current when the inductance becomes
10% lower than its initial value or the current when the
temperature of coil increases A T20°C. The smaller one is
defined as Rated DC Current. (Ta=25°C)
