SMDR  
Unshielded SMT Power Inductors  
SMDR 0402/0802/0804/0810/1206 TYPE  
MERITEK  
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
