 
Micro Spring™
Air Core Inductors
|
New RoHS part numbers are shown.
Lead was removed from terminations. The next to the last character is now L to indicate RoHS
compliance. (View old data sheet.) |
- Inductance values from 1.65 nH to 12.55 nH (tolerances as low
as 2%)
- Tight tolerance can eliminate circuit tuning
- Flat top jacket for mechanical stability and reliable pick and
place operations
- Exceptionally high Q over a wide frequency range
- Highest possible self resonance (up to 6 GHz)
- Solder coated leads ensure reliable soldering
- RoHS-compliant 260°C compatible. Terminations: tin-silver over copper
- COTS Plus tin-silver-copper and tin-lead terminations available
- Samples of all values available in Coilcraft Designer's Kit C308

When
ordering, please specify tolerance, termination and packaging codes: e.g. 1606-10JLC |
|
Tolerance: |
G = 2%, J = 5%,
K = 10% (Table above shows stock tolerances in bold.) |
|
|
Termination: |
L
= RoHS compliant tin-silver (96.5/3.5) over copper.
Special order, added cost: T
= RoHS tin-silver-copper (95.5/4/0.5) over copper or
S
= non-RoHS tin-lead (63/37) over copper. |
| |
Packaging: |
C =
7" machine-ready reel.
EIA-481 embossed plastic tape, 500 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.
