High-Performance Conductive Tantalum Capacitors: A Reliable Energy Solution for Miniaturized Electronic Devices

In today's rapidly evolving electronics industry, miniaturization, high performance, and high reliability have become key trends. YMIN's TPA16 series of conductive tantalum capacitors are high-end products meticulously designed and manufactured to meet the stringent component demands of modern electronic devices, providing a stable and reliable energy solution for various electronic systems.

Product Core Technical Features

The TPA16 series of conductive tantalum capacitors utilizes advanced materials and manufacturing processes, delivering superior electrical performance and reliability. This series achieves high performance in an extremely small size (3.2×1.6×1.6mm), demonstrating impressive technical advantages in miniaturized design.

The products offer an extremely wide operating temperature range of -55°C to +105°C, adapting to various harsh environmental conditions. The rated operating voltage range, from 2.5V to 25V, covers most low-voltage applications. Capacitance values ​​range from 6.8 to 100μF (measured at 120Hz/20°C), with a capacitance tolerance within ±20%, meeting the design requirements of precision circuits.

This series of tantalum capacitors features extremely low equivalent series resistance (ESR), below 200mΩ at 100kHz, enabling excellent performance in high-frequency applications. Furthermore, the loss tangent (Tanδ) is extremely low, exceeding 0.1 at 120Hz/20°C, minimizing energy loss.

Regarding leakage current performance, after charging for 5 minutes at rated voltage, the measured leakage current is well below industry standards. The specific value varies depending on the rated voltage, ranging from 15μA to 25μA. This performance is particularly important for battery-powered devices, significantly extending their battery life.

Excellent Reliability and Durability

The TPA16 series tantalum capacitors undergo rigorous quality control and reliability testing. Durability testing shows that after applying the rated operating voltage for 2000 hours at 105°C, the capacitance change remains within ±20% of the initial value, the loss tangent does not exceed 150% of the initial specification, and the leakage current remains within specifications.

High-temperature and high-humidity environmental testing also yielded satisfactory results. After a 500-hour no-voltage storage test at 60°C and 90%-95% relative humidity, the capacitance change remained between +40% and -20% of the initial value, the loss tangent did not exceed 150% of the initial specification, and the leakage current remained within 300% of the initial specification. These data fully demonstrate the product's excellent stability in harsh environments.

The product's surge voltage withstand capability reaches 1.15 times the rated voltage, providing an additional safety margin. The rated ripple current capability varies with ambient temperature: a factor of 1 in the -55°C to 45°C range, a factor of 0.7 in the 45°C to 85°C range, and a factor of 0.25 in the 85°C to 105°C range. Furthermore, the ripple current correction factor has been carefully optimized at different frequencies, achieving a correction factor of 1 in the 100-300kHz high-frequency range, making it particularly suitable for high-frequency switching power supply applications.

Wide Applications

The TPA16 series conductive tantalum capacitors, with their excellent performance characteristics, have found widespread application in a wide range of fields.

In the communications equipment sector, these products are widely used in mobile phones, wireless network equipment, satellite communication systems, and communications infrastructure, primarily for filtering, coupling, and power management. Their miniaturization is particularly well-suited for space-constrained modern communications equipment, while their low ESR ensures the integrity of high-frequency signal processing.

Computers and consumer electronics are another important application market for the TPA16 series. In computer motherboards, power modules, display devices, and audio equipment, these tantalum capacitors perform critical tasks such as voltage stabilization, charge storage, and current smoothing. The product's high reliability ensures long-term stable operation of computer systems, while its low leakage current helps reduce system power consumption.

Industrial control systems place extremely high demands on component reliability and environmental adaptability. The TPA16 series plays a vital role in industrial automation equipment, robotic control systems, and various industrial instruments, primarily for power management, signal processing, and circuit protection. Its wide operating temperature range and high moisture resistance make it suitable for a wide range of industrial environments.

Medical electronic devices are a traditional application for tantalum capacitors and one of the most stringent quality requirements. The TPA16 series is widely used in medical imaging equipment, pacemakers, and implantable medical devices, providing reliable power management and signal processing. Product consistency and reliability are directly related to the safety and effectiveness of medical devices, so manufacturers hold product quality requirements to an almost stringent standard.

Technical Advantages

Compared to traditional capacitors, the TPA16 series conductive tantalum capacitors offer multiple technical advantages. First, its extremely high capacitance density allows it to deliver high capacitance within a small footprint, a characteristic that is particularly important in the trend toward miniaturization of modern electronic devices.

Second, it offers excellent stability and reliability. The stable chemical properties of tantalum metal enable tantalum capacitors to maintain stable performance and a long service life under various environmental conditions. Their low ESR and low leakage current ensure efficient system operation and reduce energy waste.

Furthermore, these products comply with the RoHS Directive (2011/65/EU) and are free of hazardous substances such as lead, mercury, and cadmium, meeting the environmental requirements of modern electronic products. The manufacturer has also established a comprehensive quality traceability system, ensuring that every product can be traced back to the raw material batch and production process.
