1. When ordering, please specify termination and packaging codes:
DS1608B-106MLC
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.
Specifications subject to change without notice.
