Inductance measured at 150 MHz on an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A test fixture and correlation. 3. Q measured at 150 MHz on an Agilent/HP 4291A or equivalent with a 16193A test fixture or equivalent. 4. SRF measured on an Agilent/HP 8753ES network analyzer or equivalent with a Coilcraft CCF1268 test fixture. Parts with SRF >5 GHz are verified to >5 GHz in screening 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. Dimensions are in inches mm AT439RAT AT470RAT Terminations Tin-lead (63/37) over copper Ambient temperature –60°C to +150°C with Imax current, +150°C to +200°C with derated current Storage temperature Component: –60°C to +200°C. 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) Enhanced crush-resistant packaging AT439RAT: 700/7″ reel Plastic tape: 12 mm wide, 0.32 mm thick, 8 mm pocket spacing, 3.3 mm pocket depth AT470RAT: 500/7″ reel Plastic tape: 16 mm wide, 0.28 mm thick, 8 mm pocket spacing, 3.4 mm pocket depth PCB washing Only pure water or alcohol recommended Special materials allow operation in ambient temperatures as low as –60°C and up to 200°C. ■ Passes NASA low outgassing specifications ■ Tin-lead (Sn-Pb) terminations ensures the best possible board adhesion
