1.Specify tolerance, termination and packaging codes:
2508-27NJLC
Tolerance:G
=2% J = 5%
Termination:L=RoHS compliant tin-silver (96.5/3.5) 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 (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. Factory order only, not stocked (3500 parts per
full reel).

2. L and Q measured at 250 MHz, 0.1 Vrms, 0 A using an Agilent/HP
4291A impedance analyzer with an Agilent/HP 16193A test fixture.
3. Tolerances in bold are stocked for immediate shipment.
4. SRF measured using an Agilent/HP 8753 network analyzer and a Coilcraft SMD-D test fixture.
5. DCR measured using a micro-ohmmeter.
6. Current that causes a 15°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute
maximum ratings.
7. Electrical specifications at 25°C.
