D = 13″ machine-ready reel. EIA-481 em-
bossed plastic tape. Factory order only,
not stocked (700 parts per full reel)
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an
Agilent/HP 4284A or equivalent.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 4395A network
analyzer and an Agilent/HP 16193A test fixture.
5. DC current at which the inductance drops the specified
amount from its value without current.
6. Current that causes the specified temperature rise from
25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
