MERITEK SMDR0402-102K

SMDR Series
Unshielded SMT Power Inductors
MERITEK
SMDR 0402/0802/0804/0810/1206 TYPE
FEATURES
• High power, high saturation, low resistence
• Ideal inductors for DC-DC conversion in notebook
computer, PDAs, Step-up or step-down converters, flash
memory programmers, etc.
• SMDR0402 used ceramic base with gold-planting
• The others used LCP plastic base
CHARACTERISTICS
• I sat: The current when the inductance becomes 10%
lower than its initial value. (Ta = 20 ºC)
• I rms: The current when temperature of coil increases up
to Max. T = 40 ºC (Ta = 20 ºC)
• Operating temperature: -40 to 85 ºC
APPLICATIONS
• Portable telephones
• Personable computers
• DC/DC converters, etc.
• Other various electronic appliances
