AIRCOREINDUCTORS
AirCoreInductorsforCriticalApplications ST536RAT
■ Air core inductors feature higher Q, L and current ratings
■ Rigid package provides a flat surface for pick and place
■ Leads are locked in position for precise terminal spacing
Terminations RoHS compliant tin-silver over copper. Other termina-
tions available at additional cost.

1. When ordering, please specify tolerance, termination and testing codes:
ST536RATR54GLZ
Tolerance:
Termination: L = RoHS compliant tin-silver over copper.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or
S = non-RoHS tin-lead (63/37) over copper.
Z = COTS
H = Screening per Coilcraft CP-SA-10001
G = 2% J = 5%
Testing:
2. Inductance measured at 50 MHz on an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A test fixture and correlation.
3. Q measured at 50 MHz on an Agilent/HP 4291A or equivalent with a 16193A test fixture or equivalent.
4. SRF measured on an Agilent/HP 8753ES or equivalent with a Coilcraft CCF1268 test fixture.
5. DCR measured on a Keithley 580 Micro-Ohmmeter or equivalent.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Specifications subject to change without notice.
