SOLID TANTALUM ELECTROLYTIC CAPACITORS – F93 Series Overview

The F93 Standard Series of solid tantalum electrolytic capacitors provided in this datasheet are designed to be resin-molded chips that are compliant with the RoHS directive (2002/95/EC). These capacitors are suitable for a temperature range of -55°C to +125°C, with the rated temperature being 85°C. Notably, the capacitors maintain a capacitance tolerance of ±20% or ±10% when measured at 120Hz.

Performance Characteristics

Leakage Current: The datasheet specifies the leakage current limits for these capacitors. At 20°C, after applying the rated voltage for a minute, the leakage current must not exceed either 0.01CV or 5μA, whichever is greater. Similarly, at 85°C and with the same voltage application, it should not surpass 0.1CV or 5μA. There’s also a specification for leakage current at 25°C after applying a derated voltage.

Capacitance Change by Temperature: The capacitors exhibit stability in capacitance change across temperatures, with the maximum variance being +15% and no less than -10%. This is after exposing the capacitors to a damp heat test at 40°C with a relative humidity of 90 to 95% for 500 hours, even without voltage applied. Detailed changes in capacitance and dissipation factor related to temperature cycles, soldering heat, and endurance tests reference further pages in the datasheet for specifics.

Reliability Tests

The capacitors are tested for reliability through various stresses, such as temperature cycles and soldering heat. After undergoing tests like the surge test at 85°C and the endurance test at 85°C or 125°C, capacitors must meet certain characteristic requirements.

Mechanical Robustness

Mechanical tests are about the capacity to endure physical stresses. The shear test, for instance, involves applying a horizontal force to the capacitor’s side for a set time to ascertain that there’s no exfoliation at the terminal electrode. The terminal strength test checks for the capacitor’s resilience when the substrate is bent to a specified degree.

Product Coding and Standards

To aid in product identification and selection, a type numbering system is provided (e.g., “10V 10μF” denotes a capacitor with a rated voltage of 10V and a capacitance of 10μF). The rating code for voltage and capacitance (e.g., “20V 624” which stands for 20 volts and a capacitance code of 624) is further outlined, assisting in decoding the specifications of each capacitor within the series.

Availability and Development

While standard ratings for the capacitors are listed, the datasheet indicates the ongoing development of certain series (CAL8100B). It urges potential users to get in touch with local Nichicon sales offices when considering including these capacitors in their applications. Additionally, compliance to AEC-Q200 standard is available, with a recommendation to contact the Nichicon sales office for more information.

Overall, the datasheet provides comprehensive details on the specifications, performance, and reliability tests for the F93 Series of solid tantalum electrolytic capacitors, suggesting its applicability in a wide range of electronics due to its robust and stable characteristics.
