Tantalum Chip Capacitor Raises Capacitance

A new solid tantalum chip capacitor has been designed with new E and R case sizes, as well as ultra-low equivalent series resistance and high capacitance values. The Sprague conformal-coated 597D multi-anode capacitor provides increased reliability and improved reception in dc/dc conversion, line cards, mother boards, and power supply applications in end products including test equipment, PCs and base stations. The product’s maximum ESR values range from 13 to 35 mΩ within a temperature range of +25°C to +100°C. Capacitance values range from 22 to 1,500 µF with standard tolerances of ±10% and ±20%, and working voltage ranges from 4 to 50 Vdc. Maximum current leakage ranges from 27 to 68 μA, and the maximum dissipation factor is 6% at +25°C and 120 Hz. Capacitors in the E case size measure 7.3 mm x 4.3 mm with a 4.0 mm height profile. The R case measures 7.3 mm x 6.0 mm with a 3.6 mm height profile. Operating temperature for the 597D capacitor ranges from –55°C to +85°C, up to +125°C with voltage derating.
