Operating Temperature: -40˚C to +85˚C

Storage Temperature: -10˚C to +40˚C andRH 70% (Max.)

• High DC bias current due to trench technology

• Much lower profile than any other series

• Monolithic structure for high reliability

• Excellent solderability and heat resistance

• Magnetically shielded structure to eliminate cross coupling

Unless otherwise specified, the standard atmospheric conditions for measurement/test as:

a. 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

ASMPH family is a miniature type of multilayer power

inductors constructed using low loss ferite material to

support high-speed switching frequencies.The compact

size and high efficiency is ideal for DC/DC converter

applications in space limited boards.

Switching mode regulators for smart phones and cameras.

Buck convertersfor RFIC, RFPA and Audio Codec modules.

Boost converters for flash drivers.

Wireless cards, DVD players and other electronic devices.
