2. Tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP
4263B LCR meter or equivalent.
3. DC current at 25°C that causes a 10% (typ) inductance
drop from its value without current.
4. Current that causes the specified temperature rise from
25°C ambient.This information is for reference only and
does not represent absolute maximum ratings.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before
soldering.
