Wet Tantalum capacitors -six Gold Standards for Harsh Environment Applications

In critical industries such as aerospace, defense, and oil exploration, electronic components must endure extreme temperatures, mechanical stress, and voltage fluctuations. Hongda Capacitors’ Wet Tantalum Capacitors emerge as the ultimate solution, leveraging advanced electrochemical technology to deliver unmatched reliability and performance.

Hongda Capacitors’ wet Tantalum Capacitors excel in environments where failure is not an option:

• Aerospace: Satellites, rockets, and avionics systems.

• Defense: Missile guidance, radar, and military electronics.

• Energy: Down-hole drilling tools and offshore platforms.

• Industrial: High-temperature sensors and heavy machinery controls.

Hongda capacitor's wet tantalum series can meet these 6 golden standards.

1.Ultra-Low DC Leakage

Performance: The 135D series achieves DCL as low as 1 µA at 25°C, minimizing power loss in DC circuits.

Long-Term Efficiency: The electrochemical process reduces leakage over time, optimizing battery life and system stability.

2.Reverse Voltage Tolerance

Safety Design: Wet tantalum capacitors with tantalum metal cases withstand up to 3V of reverse voltage, preventing catastrophic failures common in solid tantalum or silver-cased alternatives.

3.High Ripple Current Handling

Example: The 10 V, 750 µF 135D series handles 2,360 mA at 40 kHz, outperforming aluminum electrolytic capacitors by 20–30%.

Heat Management: Efficient ripple dissipation ensures stable operation under heavy loads.

4.No Derating Below 85°C

Design Flexibility: Full-rated performance is maintained at 85°C, enabling higher capacitance density compared to solid tantalum capacitors (which require up to 50% derating).

5.Extreme Temperature Capability

Industry-Leading: the HCA53 series operates at +200°C, surpassing standard wet tantalum limits (+125°C) for down-hole drilling and aerospace applications.

6.Unmatched Longevity

Storage Stability: No aging or reforming is needed after prolonged storage, with shelf life limited only by environmental conditions.

Proven Legacy: Selected models have served in avionics for over 50 years, demonstrating zero premature failures.

Hongda Capacitors’ Wet Tantalum Capacitors redefine reliability in harsh environments. With unrivaled thermal stability, low leakage, and mechanical toughness, they enable mission-critical systems to perform flawlessly under extreme conditions.
