This robust version of Coilcraft’s standard 1812CS
series features high temperature materials that pass
NASA low outgassing specifications and allow opera-
tion in ambient temperatures up to 155°C. The leach-
resistant base metalization with tin-lead (Sn-Pb) termi-
nations ensures the best possible board adhesion.
■Higher SRF values than 1812 size parts with ferrite cores
■5% tolerances for all values
■19 inductance values from 1.0 to 33 µH
Core material Ceramic
Terminations Tin-lead (63/37) over silver-platinum-glass frit
Ambient temperature –55°C to +125°C with Imax current, +125°C
to +155°C with derated current
Storage temperature Component: –55°C to +155°C.
Packaging: –55°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Temperature Coefficient of Inductance (TCL) +25 to +155 ppm/°C
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Enhanced crush-resistant packaging 600 per 7″ reel
Plastic tape: 12 mm wide, 0.3 mm thick, 8 mm pocket spacing,
3.7 mm pocket depth

2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286 impedance analyzer or equivalent with Coilcraft-provided
correlation pieces.
3. Q measured at the same frequency as inductance using an Agilent/
HP 4291A with an Agilent/HP 16197A test fixture or equivalents.
4. SRF measured using an Agilent/HP 8753ES network analyzer or
equivalent and a Coilcraft SMD-D test fixture.
5. DCR measured on a micro-ohmmeter.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
