■

Higher inductance values than ceramic 0603 inductors

■

Heavier gauge wire for low DCR

Ferrite construction for high current handling

■

Inductance values from 15 nH to 10 µH

1. When ordering, please specify

termination and testing codes:

ST312RAM103JRZ

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

nickel over silver-platinum-glass frit or

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

silver-platinum-glass frit.

Testing:

Z = COTS

H = 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.

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.
