1. When ordering, specify tolerance, termination and testing codes:
ST413RADR10GLZ
Tolerance: F 1% G = 2% J = 5%
Termination: L = RoHS compliant silver-palladium-platinum glass frit.
Special order:
S = Tin-lead (63/37) over silver-platinum-glass frit.
T = Tin-silver-copper (95.5/4/0.5) over silver-platinum-
glass frit.
Testing: Z = COTS
H = Group A screening per Coilcraft CP-SA-10001
2. Part is wound on low profile coilform.
3. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286A impedance analyzer or equivalent with Coilcraft-provided
correlation pieces.
4. Q measured using an Agilent/HP 4291A with an AgilentHP 16197A
test fixture or equivalents.
5. SRF measured using an Aglilent/HP 8753ES network analyzeror
equivalent and a Coilcraft SMD-D test fixture.
6. DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a
Coilcraft CCF858 test fixture.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
