■Features
-The
miniature chip inductors is wound on a special ferrite core.
-VLH322515/322520/453226
are low DC resistance.
-VLH322520C/453226C/565047C
are low DC resistance, high
current capacity, and high impedance characteristics. They are
excellent for using as a choke coil in DC power supply circuits.

■Characteristics
for252010E/ 252012E/252510/322515C
-Rated
DC Current(I sat): The current when the inductance becomes
30% typical its initial value (Ta=25°C)
-Temperature
Rise Current(I rms):
The actual current when the
temperature of coil becomes
∆ T40℃..
(Ta=25°C)
-Operating
temperature range: -40½105°C
■Characteristics
except 252010E/252012E/252510/322515C
-Rated
DC Current: The current when the inductance becomes 10% lower than its
initial value or the current when the temperature of coil increases
∆ T20℃.
The
smaller one is defined as Rated DC Current. (Ta=25°C)
-Operating
temperature range: -40½105°C
