AVX Reduces ESR of Polymer Tantalum Capacitors

09 February 2016

AVX Corporation has reduced the ESR of its F38 Series polymer tantalum capacitors. The F38 Series polymer tantalum capacitors are currently available in two miniature cases sizes, 0603 and 0805, with ultralow profiles of 0.9mm and 1.0mm, voltage ratings spanning 6.3 V to 10V, and capacitance values spanning 2.2 μF to 68 μF with a ±20% tolerance at 120Hz. They offer the lowest ESR of small case size polymer capacitors, according to the company.

Made of conductive polymer materials and featuring SMD facedown terminals, the F38 Series capacitors exhibit high conductivity, low ESR, low ESL, and high ripple current capabilities. The series also offers a more benign failure mode than traditional SMD electrolytic capacitors, and is suited for use in microminiature hybrid circuits and handheld and wearable electronics.

Lead-free compatible and RoHS-compliant per the RoHS2 directive 2011/65/EU, the capacitors are rated at 85 °C and designed for use in operating temperatures spanning -55 °C to +105 °C. Lead time for the series is 8–10 weeks.
