AVX Develops New NOM OxiCap Capacitor Series

AVX Corp. (Myrtle Beach, SC) has developed a new niobium-oxide multi-anode (NOM) capacitor, designed to deliver low ESR, high capacitance, high ripple current capacitor performance. Designated the OxiCap™ Series, the new family of capacitors provides a safe (non-burning), high-resistance failure mode. The OxiCap NOM features a multi-anode configuration in a standard "E" (7343-43) case package. It is suitable for power supply decoupling and high-speed data processing applications.

The OxiCap capacitors provide a readily available alternative anode material. Niobium-oxide is a low-density material, providing lighter overall package weight. In addition, the multi-anode cap replaces up to three single anode caps, delivering higher performance while reducing board space and placement costs. The OxiCap Series solves the problems of capacitance drop and dc leakage encountered with aluminum electrolytics. A single OxiCap capacitor exhibits ESR values that normally would require up to 10 aluminum capacitors to achieve.

The OxiCap capacitors feature capacitance values ranging from 220 µF to 470 µF, with capacitance tolerances at ±20 percent. Voltage rating options are 2.5 W/Vdc, 4.0 W/Vdc and 6.3 W/Vdc. The operating temperatures range from –55 °C to +125 °C. Pricing starts at $2.55 for the OxiCap NOM capacitors in quantities of 10,000 to 100,000, with lead times from stock to eight weeks.
