Ambient Temperature: 20±15˚C b. Relative Humidity: 65±20% c. Air Pressure: 86 kPa to 106 kPa Inductance (L): HP4291B+HP16192A or Equivalent, tested at 1MHz, -20dBm or 50mV. Direct Current Resistance (DCR): Milliohmeter-HP4338B or Equivalent Self-Resonant Frequency (SRF): HP4291B+HP16192A or Equivalent, -20dBm or 50mV. Temperature Rise current (Irms): Electric Power, Electric current meter, Thermometer. Irms is the value of DC current as chip surface temperature rose just 40°C against chip initial surface temperature. Saturation Current (Isat): HP6632B system DC power supply, HP4291B+HP16192A+HP16200A or equivalent. Isat is the value of DC current as inductance decreased just 30% against initial value ABRACON IS ABRACON IS 9001:2008 ISOISO 9001 / QS 9000 CERTIFIED CERTIFIED Visit www.abracon.com for Terms & Conditions of Sale Revised: 02.12.13 30332 Esperanza, Rancho Santa Margarita, California 9268 tel 949-546-8000 | fax 949-546-8001 | www.abracon.com SMD Multilayer Chip Power Inductor ASMPH-1008 RoHS/RoHS II Compliant Pb 2.5 x 2.0 x 0.9mm PART IDENTIFICATIONS: ASMPH-1008Inductance Code Please refer to the table above Packaging Tolerance M=±20% N=±30% T: Tape and Reel (3kpcs / reel) OUTLINE DRAWING: Recommended Land Pattern L 2.5±0.2 W T 2.0 (+0.3, -0.1) 0.9±0.1 a A B C 0.5±0.3 1.0~1.4 0.6~1.0 1.8~2.2 Dimension: mm MATERIALS: Side View Top View 1 ABRACON IS ABRACON IS 9001:2008 ISOISO 9001 / QS 9000 CERTIFIED CERTIFIED 2 3 4 1 2 3 Part Name Base Material Internal Conductor Pull out Electrode 4 Terminal Electrode Material Ferrite Ag Ag Ag (Inner layer) Ni-Sn (Outer layer) Visit www.abracon.com for Terms & Conditions of Sale Revised: 02.12.13 30332 Esperanza, Rancho Santa Margarita, California 9268 tel 949-546-8000 | fax 949-546-8001 | www.abracon.com SMD Multilayer Chip Power Inductor ASMPH-1008 Pb RoHS/RoHS II Compliant 2.5 x 2.0 x 0.9mm REFLOW PROFILE: Preheat Condition Allowed time above 217 ˚C Max temperature Max time at max temperature Solder paste Allowed Reflow time 150 to 200 ˚C; 60 to 120 sec. 60 to 90 sec. 260 ˚C 10 sec.
