Sumida has developed a new type of high-current power inductor CDPQ2419. This surface-mounted product can be used for PV inverter (Photovoltaic) and UPS power supply as well as for mobile phone base station. It can withstand saturation current of 100A (3.3uH).
Size: 26.5 x 27.5 x H20.0 mm (max.)
Product Weight: 38g (ref.)
Operating Temperature Range: -40°C to +125°C
(Including coil’s self temperature rise)
High Current Inductor for DC/DC converters in distributed power systems and PV inverters etc.

※1 Measuring condition at 100kHz 0.1V.
※2 Saturation current: This indicates the actual value of D.C. current when the inductance becomes 20% lower than its initial value.
※3 Temperature rise current: The actual value of D.C. current when the temperature of coil becomes △T=40°C (Ta＝20°C).
