Termination: L
= RoHS compliant silver-palladium-platinum-glass frit
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 (1000 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 (3500 parts per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms 0 Adc.
3. DC current at which the inductance drops 10% (typ) from its value
without current.
4. Current that causes a 40°C temperature rise from 25°C ambient.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
