Unshielded SMT Power Inductors

SMDR 0402/0802/0804/0810/1206 TYPE

SMDR

Series

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
