Myrtle Beach, S.C. Helping design engineers to comply with emerging international directives such as Reduction of Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE) legislation, AVX has developed a new series of low equivalent series resistance (ESR) conductive polymer tantalum capacitors specifically designed to withstand the higher temperatures required for lead-free soldering processes and are capable of withstanding 260°C reflow temperatures three or even four times, said the company.
The TCJ capacitors are constructed using a conductive polymer cathode technology that enables users to take advantage of the volumetric efficiency of tantalum, reduced ESR in addition to withstanding lead-free soldering temperatures.
Available in A and B case sizes, the TCJ Series capacitors are available in capacitance values from 4.7 to 150 microfarads (μF) in voltage ratings of 4 V, 6.3 V and 10V. The operating temperature range is -55°C to 125°C.
The TCJ series devices exhibit excellent ESR characteristics. For example, an A case size (1206) 10 μF tantalum capacitor with a traditional manganese dioxide cathode typically has an ESR measured in ohms, while the equivalent TCJ Series device has an ESR of less than 300 milliohms, which makes the new capacitors suitable for high-frequency and high-speed digital circuits, said the company.
Typical pricing for the TCJ Series capacitors ranges from $0.25 to $0.35 in quantities of 10,000. Delivery is eight to ten weeks. Samples are available immediately.
