Tantalum Capacitors Offer Very Low ESR Ratings in C Case Size
Mon, 02/08/2010 - 7:30am
A new low ESR tantalum capacitor range which includes for the first time low ESR 330µF/6.3V parts in a C case size (6032-26) is available from AVX Corporation. Previously, the only low ESR option within this capacitance/voltage (C/V) ratio was only available in the larger D case size (7343-31). With an ESR as low as 80m, TPS Series capacitors are suitable for smoothing and filtering on 3.3 V power rails, a common output voltage of DC/DC converters. Thanks to its high capacitance capability, the TPS Series capacitors can also be used for battery support in handheld devices, where small size is a key design requirement. The TPS Series tantalum capacitors have a maximum direct leakage current of 19.8µA and a maximum dissipation factor at 120 Hz of 12%. Operating temperature range is -55°C to +125°C. In addition, these devices meet the requirements of AEC-Q200 for the automotive industry.
