Nichicon Solid Tantalum Electrolytic Capacitors F91 and F92 Series Datasheet

Category: Capacitors, Electronics, Nichicon America Corporation

Overview of Nichicon Solid Tantalum Electrolytic Capacitors F91 and F92 Series

The Nichicon F91 and F92 series represent a range of resin-molded chip solid tantalum electrolytic capacitors suited for surface-mount device (SMD) applications in high-frequency environments. These capacitors are in full compliance with the RoHS directive (2002/95/EC) and are designed to offer low equivalent series resistance (ESR), making them ideal for the electronics industry where high performance and reliability are crucial.

Key Performance Characteristics and Ratings

The datasheet presents the capacitors’ performance characteristics which include a wide operating temperature range from -55°C to +125°C, with a rated temperature of +85°C. Capacitance tolerance is specified at ±20% or ±10%, measured at 120Hz. The dissipation factor and ESR vary across models and are detailed in the provided tables.

Leakage current parameters are also provided, showing maximum allowable leakage after a minute’s application of rated voltage at 20°C, after application at 85°C, and after application of derated voltage at 125°C. In addition to operational leaks, the capacitors are tested for their endurance and stability in various conditions such as damp heat, temperature cycles, and exposure to soldering heat.

Mechanical Tests and Designation

Capacitors in this series are subjected to rigorous mechanical tests including the shear test and the terminal strength test to ensure the device’s integrity in harsh mechanical environments.

The type numbering system is detailed for both F91 series examples (such as “F910J337MNC”) and the F92 series (like “6.3V 1OF”), which describe the different capacitance and voltage ratings available within the series. Each part number is methodically constructed to convey a wealth of information such as rated capacitance, voltage, capacitance tolerance, and packaging code.

Standard Ratings and Additional Information

The provided standard ratings table lists specific models with their associated capacitance values ranging from 0.22µF to 470µF and rated voltages from 6.3V to 250V. Capacitance codes are given for each case size to assist in product selection and design integration. Nichicon encourages contacting local sales offices for information on developing series.
