AIR CORE INDUCTORS
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.
Ambient temperature  –40°C to +125°C with Imax current, +125°C
to +140°C with derated current
Storage temperature  Component: –40°C to +140°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat  Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Temperature Coefficient of Inductance (TCL)  +5 to +70 ppm/°C
Moisture Sensitivity Level (MSL)  1 (unlimited floor life at <30°C /
85% relative humidity)
Packaging  800 per 13″ reel  Plastic tape: 24 mm wide,
0.3 mm thick, 12 mm pocket spacing, 6.1 mm pocket depth

1. When ordering, please specify tolerance, termination and testing codes:
ST536RATR54GLZ
Tolerance: G = 2%  J = 5%
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.
Testing:
Z = COTS
H = Screening per Coilcraft CP-SA-10001
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.
