2005 POWER INDUCTORS High-Reliability Power Inductors MS319PZA ■ High temperature material allows operation in ambient temperatures up to 155°C ■ Tin-lead (Sn-Pb) termination for the best possible board adhesion ■ Lowest profile, ultra-miniature, magnetically shielded power inductor; only 0.5 mm high, 2 mm × 2 mm footprint ■ 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. Core material Composite Terminations Tin-lead (63/37) over tin over nickel over silver-platinum. Weight 8.4 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 Plastic tape: 8 mm wide, 0.28 mm thick, 4 mm pocket spacing, 0.76 mm pocket depth Part number1 MS319PZA151MSZ MS319PZA221MSZ MS319PZA331MSZ MS319PZA471MSZ MS319PZA681MSZ Inductance2 ±20% (µH) 0.15 0.22 0.33 0.47 0.68 DCR (Ohms)3 nom max 0.085 0.098 0.111 0.128 0.144 0.166 0.177 0.204 0.215 0.247 SRF typ4 (MHz) 590 480 380 275 220 10% drop 1.05 0.72 0.65 0.60 0.50 Isat (A)5 Irms (A)6 20% drop 30% drop 20°C rise 40°C rise 1.55 1.90 1.25 1.60 1.20 1.50 1.13 1.48 1.05 1.30 1.00 1.30 0.97 1.20 0.95 1.25 0.75 0.95 0.80 1.05 1.
