Product Identification

· Pagers, Cordless Phone.
· High Frequency Communication Products.
· Personal Computers.

· Disk Drives And Computer Peripherals.
· DC Power Supply Circuits.

· 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.

for 252010E / 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 ΔT40°C.

(Ta=25°C)
- Operating temperature range: -40 ~ 125°C

 

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 ΔT20°C. The smaller one is defined as Rated DC Current.

(Ta=25°C)
- Operating temperature range: -40 ~ 125°C
