TQD28: High-Performance Conductive Polymer Tantalum Capacitors Powering Modern High-Density Electronic Devices
In today's rapidly evolving electronics industry, the intelligentization, miniaturization, and efficiency of equipment have become irreversible trends. From high-speed AI data centers to precision-controlled automotive electronics, from agile drones to stable and reliable communication base stations, each generation of electronic devices places increasingly stringent demands on core components: providing stable, clean, and robust power support within extremely limited space. YMIN understands this well, leveraging its deep expertise in materials science and manufacturing processes to launch the TQD28 series of conductive polymer tantalum capacitors. With their superior overall performance, these capacitors are a powerful tool for engineers to address the dual challenges of space and performance.
The most obvious advantage of the TQD28 series lies in its compact physical structure. Measuring only 7.3mm (length) x 4.3mm (width) x 2.8mm (height), it achieves an ultra-thin, flat design. This "slimming down" is not achieved at the expense of electrical performance, but rather through precise internal structural optimization and advanced material forming technology. For modern electronic products seeking ultra-thin and lightweight designs, such as ultra-thin laptops, motherboards for high-end smartphones, compact PD fast chargers, and wearable devices, the TQD28 can be easily embedded in the narrow gaps of PCB boards, providing unprecedented flexibility in board layout and enabling more attractive industrial designs.
The core value of the TQD28 lies in its excellent electrical parameters. It uses a highly conductive polymer as the cathode material, replacing manganese dioxide in traditional tantalum capacitors, resulting in revolutionary performance improvements:
• Ultra-low ESR and high ripple current capability:
The conductivity of conductive polymer materials is far higher than that of traditional electrolytes, giving the TQD28 extremely low equivalent series resistance at 100kHz. The direct benefit of low ESR is that the capacitor's own heat generation is minimized when large ripple currents are passed. The TQD28 can withstand ripple currents of up to several amperes at an ambient temperature of 45°C and 100kHz, which is crucial for handling the high-frequency charging and discharging of switching power supplies. For example, capacitors in server motherboard CPU/GPU power supply circuits (VRM), motor driver inverter circuits, and onboard DC-DC converters in new energy vehicles need to continuously withstand high current surges. The TQD28's low ESR and high ripple current capability ensure low temperature rise and long lifespan under harsh operating conditions, fundamentally avoiding the risk of performance degradation or failure due to capacitor overheating.
• Stable Capacitance Over a Wide Temperature Range:
The TQD28 boasts a wide operating temperature range of -55℃ to +105℃, and its capacitance remains stable across the entire temperature range. Whether in automotive electronic systems starting in cold environments or next to AI data server chips operating at continuously high temperatures, the TQD28 provides a relatively stable capacitance value, ensuring the continuity of filtering and decoupling effects without performance degradation due to drastic fluctuations in ambient temperature.
• Reliable Durability and Stability:
Sungming employs extremely rigorous quality verification procedures for the TQD28. The product underwent 2000 hours of high-temperature load life testing (at rated voltage and 105°C) and 500 hours of high-temperature and high-humidity no-load testing. Test results show that its capacitance change rate, loss tangent, and leakage current are all far superior to standard requirements. This demonstrates that the polymer material inside TQD28 possesses excellent oxidation resistance and long-term stability, capable of withstanding prolonged and harsh environmental conditions, making it particularly suitable for mission-critical applications requiring high reliability and long lifespan, such as industrial robots, military projects, communication infrastructure, and energy metering equipment.
These characteristics of TQD28 make it stand out in several high-end application scenarios:
• Automotive Electronics:
With the increasing electrification and intelligence of automobiles, the number of onboard electronic control units is surging. TQD28's high-temperature resistance, high reliability, and miniaturization make it perfectly suited for engine ECUs, ADAS modules, BMS systems, etc., effectively resisting voltage surges and complex electromagnetic interference during vehicle startup, ensuring driving safety.
• AI Data Servers/Communication Equipment:
The ever-increasing power density of server CPUs, GPUs, and ASIC chips demands nanometer-level response speeds for power supply network decoupling and filtering. The TQD28's low ESL/ESR characteristics provide these power-hungry chips with the closest and purest current "reservoir," significantly reducing power supply noise, ensuring optimal chip computing power, and minimizing data errors and system downtime.
• Robots and Drones:
These devices are space-constrained, and their current demands change dramatically during movement. The TQD28's small size and fast response capabilities enable efficient decoupling in the main control board and servo drive components, ensuring precise execution of control commands and stable power output.
• PD Chargers and Smart Meters:
In the PD fast charging field, which pursues high power density (watts per cubic inch), the TQD28 helps reduce PCB area and achieve higher power output. In smart meters and water meters, its low leakage current and long lifespan ensure accurate metering and reliable outdoor operation for many years.
