1. When ordering, please specify termination and packaging codes:
µA377±-ALC
Termination: L
=
RoHS compliant tin-silver over copper.
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 (100 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. Factory order only, not stocked (500 parts per
full reel).
2. Inductance measured at 500 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-A fixture in an Agilent/HP 4284A LCR meter or equivalent.
3. SRF measured on an Agilent/HP 8753ES.
4. DC current at which the inductance drops 30% (typ) from its value with-
out current.
5. Current that causes a 40°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
