2006 POWER INDUCTORS High Reliability Power Inductors MS322PZA ■ High temperature materials allow operation in ambient temperatures up to 155°C ■ Tin-lead (Sn-Pb) termination for the best possible board adhesion ■ Lowest profile, ultra-miniature, shielded power inductor ■ Soft saturation makes them ideal for VRM/VRD applications. ■ Special construction allows it to pass vibration testing to 80 G and shock testing to 1000 G. Terminations Tin-lead (63/37) over copper. Core material Composite Weight 12 – 13 mg Ambient temperature –55°C to +105°C with Irms current, +105°C to +155°C with derated current Storage temperature Component: –55°C to +155°C. Tape and reel packaging: –55°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Enhanced crush-resistant packaging 2000/7″reel; 7500/13″ reel Plastic tape: 8 mm wide, 0.28 mm thick, 4 mm pocket spacing, 0.76 mm pocket depth Part number1 MS322PZA102MSZ MS322PZA222MSZ MS322PZA332MSZ MS322PZA472MSZ MS322PZA562MSZ MS322PZA682MSZ MS322PZA822MSZ MS322PZA103MSZ MS322PZA153MSZ MS322PZA223MSZ MS322PZA333MSZ MS322PZA473MSZ MS322PZA563MSZ MS322PZA683MSZ MS322PZA823MSZ MS322PZA104MSZ DCR (Ohms)3 Inductance2 ±20% (µH) typ max 1.0 0.153 0.169 2.2 0.278 0.306 3.3 0.460 0.506 4.7 0.665 0.732 5.6 0.75 0.825 6.8 0.92 1.02 8.2 1.08 1.19 10.0 1.27 1.40 15.0 2.02 2.22 22.0 2.78 3.06 33.0 4.45 4.90 47.0 5.60 6.16 56.0 6.65 7.32 68.0 8.50 9.35 82.0 9.25 10.18 100.0 11.10 12.25 SRF (MHz)4 min typ 136 170 88 110 70 88 54 68 49 61 45 57 41 51 36 45 29.6 37 24.4 30.5 19.2 24.0 15.6 19.5 13.2 16.5 12.8 16.0 10.8 13.5 10.4 13.0 Isat (A)5 Irms (A)6 10% drop 20% drop 30% drop 20°C rise 40°C rise 0.71 1.0 1.2 0.910 1.22 0.49 0.69 0.78 0.710 0.950 0.42 0.56 0.66 0.550 0.720 0.31 0.44 0.52 0.500 0.660 0.30 0.43 0.50 0.460 0.600 0.26 0.35 0.41 0.400 0.520 0.24 0.33 0.39 0.370 0.490 0.24 0.31 0.37 0.345 0.440 0.19 0.25 0.29 0.265 0.350 0.150 0.205 0.240 0.235 0.305 0.110 0.150 0.180 0.160 0.205 0.090 0.130 0.155 0.155 0.205 0.085 0.120 0.145 0.145 0.195 0.080 0.115 0.135 0.115 0.155 0.065 0.090 0.115 0.125 0.165 0.065 0.090 0.115 0.100 0.135 1.
