  2. C1 = .07 Only 2 inputs, 1 output but still modestly complex πT = .24 Digital MOS, assuming at 45C C2 = .0016 5 pins πE = 2 Ground fixed assumed πQ = 10 Commercial part πL = 1 Out since 2007 λp = .22 fails / 10^6 hours 1/λp= 4545454.5 hours to failure TPS62203 – TI 3.3v Regulator

  3. C1 = .14 Very complex die πT = .24 Digital MOS, assuming at 45C C2 = .025 48 pins πE = 2 Ground fixed assumed πQ = 10 Commercial part πL = 1.8 Out since Jan, 2012 λp = .696 fails / 10^6 hours 1/λp= 1436781 hours to failure **16GB Micron Flash has a min of 7,992 blocks functional and a max of 8,192 when shipped MT29F16G08QAAWC - NAND Flash

  4. Capacitor, Electrolytic, Aluminum λb= .012 Base Failure Rate: assumed to be around 40C πCV= 1 Capacitance Factor: assumed to be 400uF πE= 2 Environmental Factor: Ground fixed assumed πQ = 10 Quality Factor: Commercial part λp= λb * πCV * πE * πQ = .24 fails / 10^6 hours 1/ λp = 4166666.7 hours to failure Union Battery 063450 - 1000mAh
