1. Specify

tolerance, termination

and

packaging

codes:

2508-27NJLC

Tolerance: G

= 2%

= 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

= non-RoHS tin-lead (63/37).

Packaging: C

= 7″ machine-ready reel. EIA-481 embossed plastic tape (1000 parts per full reel).

= Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.

= 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.

7. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
