1.2
4.8 Max.
Low profile (4.8mm Max. square, 1.2.mm Max. height).
Features an open magnetic circuit, but its thin dimensions
result in minimum leakage flax and result in minimum
electromagnetic interference generated.
Clears free-fall drop tests in which it is dropped onto a
concrete floor from a height of 1.5m, thus meeting
requirements specified for use in cellular phones.
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)
