2010 POWER INDUCTORS High Reliability Power Inductors MS338PWA ■ High temperature materials allow operation in ambient temperatures up to 155°C ■ Very low DCR and excellent current handling. ■ Soft saturation makes them ideal for VRM/VRD applications. ■ Tin-lead (Sn-Pb) termination for the best possible board adhesion ■ Special construction allows it to pass vibration testing to 30 G and shock testing to 500 G. Weight 20 mg Terminations Tin-lead (63/37) over tin over nickel over silver. 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. 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 1000/7″reel Plastic tape: 8 mm wide, 0.23 mm thick, 4 mm pocket spacing, 1.19 mm pocket depth DCR (Ohms)3 SRF (MHz)4 Inductance2 Part number1 ±20% (µH) nom max min typ 10% drop MS338PWA201MSZ 0.20 0.024 0.027 286 408 2.80 MS338PWA331MSZ 0.33 0.031 0.035 216 309 1.90 MS338PWA501MSZ 0.50 0.040 0.045 153 218 1.80 MS338PWA681MSZ 0.68 0.057 0.063 106 152 1.55 MS338PWA821MSZ 0.82 0.068 0.075 93 132 1.25 MS338PWA102MSZ 1.0 0.081 0.089 82 117 1.20 MS338PWA152MSZ 1.5 0.105 0.116 56 80 0.950 MS338PWA222MSZ 2.2 0.156 0.173 53 75 0.940 MS338PWA332MSZ 3.3 0.207 0.228 39 55 0.700 MS338PWA472MSZ 4.7 0.336 0.370 28 40 0.580 MS338PWA682MSZ 6.8 0.421 0.463 23 33 0.450 MS338PWA822MSZ 8.2 0.457 0.503 21 30 0.440 MS338PWA103MSZ 10 0.555 0.611 20 28 0.390 1. When ordering, please specify testing code: 2. 3. 4. 5. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc. DCR measured on a micro-ohmmeter. SRF measured using Agilent/HP 4395A or equivalent. DC current at which the inductance drops the specified amount from its value without current. 6. Current that causes the specified temperature rise fron 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
