Maxi 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 90 nH to 538 nH
Exceptionally high Q even at low frequencies
Handle up to 3.5 Amps current
Tight tolerance can eliminate circuit tuning (tolerances as low as 2%)
Flat top case for mechanical stability and reliable pick and place operations
Solder coated leads ensure reliable soldering
RoHS-compliant 260°C compatible. Terminations: tin-silver over copper
Samples of all values are available in Coilcraft Designer's Kit C319

When ordering, please specify tolerance, termination and packaging codes: e.g. 132-20SMJLD

Tolerance:

G = 2%, J = 5% (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:

D = 13″ machine-ready reel.
EIA-481 embossed plastic tape, 800 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 D instead.

2	Inductance and Q tested on an Agilent/HP 4291A with a 16193 fixture using Coilcraft supplied correlation.
3	Tolerances in bold are stocked for immediate shipment.
4	SRF tested with an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
5	DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter.
6	Irms: Current that causes a 15°C temperature rise from 25°C ambient. Details
7	Ambient temperature range:	–40°C to +125°C with Irms current. +125°C to +140°C with derated current. Derating curve
8	Storage temperature range:	Component: –40°C to +140°C Packaging: –40°C to +80°C
9	Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
10	Electrical specifications at 25°C.
11	Temperature coefficient of inductance: +5 to +70 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
