ASMPH-0603
SMD Multilayer Chip Power Inductor
FEATURES: APPLICATIONS:
1.6 x 0.8 x 0.8mm
Operating Temperature: -55 C to +125 C
Storage Temperature:
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.
Irms is the value of DC current as chip surface temperature rose just 40°C against chip initial surface
temperature.
Pb
RoHS/RoHS II Compliant
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.
ELECTRICAL SPECIFICATIONS:
Isat is the value of DC current inductance decreased just 30% against initial value.
