4020 POWER INDUCTORS High Reliability Power Inductors MS433PYA ■ High temperature materials allow operation in ambient temperatures up to 155°C ■ Tin-lead (Sn-Pb) termination for the best possible board adhesion ■ Exceptionally low DCR – 5.81 mOhm ■ Soft saturation makes them ideal for VRM/VRD applications. Terminations Tin-lead (63/37) over copper. Core material Composite Weight 0.17 – 0.18 g 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 1000/7″reel; 3500/13″ reel Plastic tape: 12 mm wide, 0.23 mm thick, 8 mm pocket spacing, 2.3 mm pocket depth Part number MS433PYA221MSZ MS433PYA401MSZ MS433PYA601MSZ MS433PYA102MSZ MS433PYA152MSZ MS433PYA222MSZ 1 Inductance2 ±20% (µH) 0.22 0.40 0.60 1.0 1.5 2.2 DCR (mOhms)3 typ max 5.81 6.40 7.55 8.30 9.50 10.45 13.25 14.60 21.45 23.60 35.20 38.70 SRF (MHz)4 min typ 153 191 116 145 85 106 63 79 51 64 42 52 1. When ordering, please specify testing code: MS433PYA222MSZ Testing: Z = COTS H = Screening per Coilcraft CP-SA-10001 N = Screening per Coilcraft CP-SA-10004 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc. 3. DCR measured on a micro-ohmmeter. 4. SRF measured using an Agilent/HP 4395A or equivalent. 5. Typical dc current at which the inductance drops 30% from its value without current. 6. Typical current that causes the specified temperature rise from 25°C ambient. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. ® Irms (A)6 20°C rise 40°C rise 12.0 16.8 10.0 14.0 7.9 11.7 6.7 9.6 5.2 7.5 4.0 5.5 Irms Testing Irms testing was performed on 0.75 inch wide × 0.25 inch thick copper traces in still air. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, and proximity to other components. Therefore temperature rise should be verified in application conditions. Specifications subject to change without notice.
