1. Please specify
tolerance, termination
and
packaging
codes:
DO1608C-105MLC
Tolerance: K
= 10%, M = 20% (Table shows stock
tolerances in bold.)
Termination: L
= RoHS compliant gold over nickel over
moly-manganese.
Special order:
T
= RoHS tin-silver-copper
(95.5/4/0.5) or
S
= non-RoHS tin-lead
(63/37).
Packaging: C
= 7″ machine-ready reel. EIA-481 em-
bossed plastic tape (750 parts per full
reel).
B
= Less than full reel. In tape, but not
machine ready.
To have a leader and trailer added ($25
charge), use code letter C instead.
D
= 13″ machine-ready reel. EIA-481 em-
bossed plastic tape (2500 parts per full
reel).
2. Tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP
4263B LCR meter or equivalent.
3. Tolerances in bold are stocked for immediate shipment
4. DC current at which the inductance drops 10% (typ) from
its value without current.
5. Current that causes the specified temperature rise from 25°C
ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before
soldering.
