1. When ordering, specify termination and packaging codes:
GA3252-ALD
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: D = 13″ machine-ready reel
EIA-481 embossed plastic tape (200 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 D instead.
2. Inductance tested at 100 kHz, 0.1 Vrms on Agilent/HP 4192A.
3. DCR measured on a Keithley 580 micro-ohmmeter or equivalent.
4. SRF measured on an Agilent/HP 8753ES network analyzer.
5. DC current at which the inductance drops the specified amount from its
value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
