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.
