FEATURESʗಛɹ௕
• Low profile (3.8mm Max. square, 1.2mm Max. height)
• Clears free-fall drop tests in which it is dropped onto a
concrete floor from a height of 1.5 m, thus meeting
requirements specified for use in cellular phones.
• Features an open magnetic circuit, but its thin dimensions
result in minimum leakage flux and result in minimum
electromagnetic interference generated.
• RoHS compliant.

(1) Inductance is measured with a LCR meter 4284A* or equivalent.
Test frequency at 100KHz
(2) DC resistance is measured with a Digital Multimeter TR6871
(Advantest) or equivalent.
(3) Maximum allowable DC current is that which causes a 30%
inductance reduction from the initial value, or coil temperature to rise
by 40°C, whichever is smaller.
(Reference ambient temperature 20°C)
