1. When ordering, please specify termination and testing codes:

ST312RAM103JRZ

Core material Ferrite

Terminations Matte tin over nickel over silver-platinum-glass frit.

Weight 4.3 – 5.7 mg

Ambient temperature –40°C to +85°C with Irms current, +85°C to

+100°C with derated current

Termination: R = RoHS compliant matte tin over nickel over silver-

platinum-glass frit.

Special order:

Q = RoHS tin-silver-copper (95.5/4/0.5) over tin over

Storage temperature Component: –55°C to +100°C.

nickel over silver-platinum-glass frit or

Packaging: –55°C to +80°C

P = non-RoHS tin-lead (63/37) over tin over nickel over

silver-platinum-glass frit.

Z = COTS

Resistance to soldering heat Max three 40 second reﬂows at

+260°C, parts cooled to room temperature between cycles

Testing:

Temperature Coefﬁcient of Inductance (TCL) +50 to +300 ppm/°C

85% relative humidity)

H = Group A screening per Coilcraft CP-SA-10001

2. Inductance measured using a Coilcraft SMD-A ﬁxture in an Agilent/

HP 4286A 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.

Packaging 2000 per 7″ reel; Paper tape: 8 mm wide, 1.0 mm thick,

4 mm pocket spacing

5. DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a

Coilcraft CCF1010 test ﬁxture.

6. Electrical speciﬁcations at 25°C.

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