1. When ordering, please specify termination and packaging codes:
DS1608B-106M
LC
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 embossed 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 embossed plastic
tape (2500 parts per full reel).
2. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc using an Agilent/HP
4263B LCR meter or equivalent.
3. Current that causes a 30°C temperature rise from 25°C ambient.
4. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Designer’s Kit C334 contains 3 of each value
