1 When ordering, please specify termination and packaging codes: e.g. SER1410-202MED
Termination: E = RoHS compliant tin-silver over copper.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging: D = 13" machine-ready reel
EIA-481 embossed plastic tape
SER1408: 300 parts/full reel;  SER1410, SER1412: 250 parts/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 measured at 100 kHz, 0.1 Vrms, using an Agilent/HP 4284A or equivalent.
3 DCR measured at 25°C on a micro-ohmmeter and a Coilcraft CCF840 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16193A test fixture. Details
5 Isat: Typical dc current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
6 Irms: Typical current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
7 Ambient temperature range: −40°C to +125°C with (40°C rise) Irms Derating curves
8 Storage temperature range: Component: −40°C to +165°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +165°C (Ambient + temperature rise)
10 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.
11 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
