Application
◾ DC-DC converters
◾ Server
Notes
◾ All data is tested based on 25℃ ambient temperature.
◾ Inductance measure condition at 100kHz, 0.5V.
◾ Saturation current：the actual value of DC current when the inductance decrease 30% of its initial value.
◾ Temperature rise current：the actual value of DC current when the temperature rise is ΔT50℃(Ta=25℃).
◾ Special remind：Circuit design, component placement, PCB size and thickness, cooling system and etc.
◾ All will affect the product temperature. Please verify the product temperature in the final application.
Save
◾ Product in packing storage condition : temperature 5～40℃, RH≤70%.
◾ If taking out for use, the remaining products should be sealed in plastic bags and preserved in accordance with the above conditions, to avoid oxidation of terminals (electrodes), affecting soldering status.
◾ A storage of Codaca Electronic products for longer than 12 months is not recommended within other effects, the terminals may suffer degradation, resulting in bad solderability. Therefore, all products shall be used within the period of 12 months based on the day of shipment.
◾ Do not keep products in unsuitable storage conditions, such as areas susceptible to high temperatures, high humidity, dust or corrosion.
◾ Always handle products with care.
◾ Don't touch electrodes directly with bare hands as oil secretions may inhibit soldering.
◾ Always ensure optimum conditions for soldering.
