Tantalum capacitors types

Tantalum capacitors can be broadly classified into several types based on their construction, electrolyte, and packaging. Here’s an overview of the main types:

·  Solid Tantalum Capacitors

·  Wet Tantalum Capacitors

·  Polymer Tantalum Capacitors

·  Tantalum Chip (SMT) Capacitors

·  Axial Lead Tantalum Capacitors

·  Radial Lead Tantalum Capacitors

Today, I would like to introduce Hongda Axial Lead Hermetically Sealed Tantalum capacitors.

CA35 series  (125°C) Hermetically Wet Tantalum Capacitors, this is a type of high-reliability capacitor designed for demanding applications, where performance and long life under extreme conditions are critical. These capacitors use tantalum as the anode material and are typically enclosed in a hermetically sealed case to protect the internal components from high-temperature and harsh-environment.

Below is a breakdown of their key features, types, and common applications.

Tantalum capacitors Key Features:

1.High Capacitance: Tantalum capacitors generally offer higher capacitance per unit volume compared to other types of capacitors.

2.Stable Electrical Performance: These capacitors maintain stable performance across a wide range of temperatures and environmental conditions.

3.Hermetically Sealed: The hermetic seal prevents moisture and oxygen from entering the capacitor, which can degrade its performance or cause failure, ensuring a longer operational life.

4.Axial Lead Configuration: In an axial capacitor, the leads extend from opposite ends of the cylindrical body, making it suitable for certain mounting configurations, especially in through-hole PCB designs.

5.High Reliability: Wet tantalum capacitors are used in environments where high reliability is crucial, such as aerospace and military applications.

6.Wet Electrolyte: These capacitors use a liquid (wet) electrolyte, which allows for higher capacitance and voltage ratings than solid tantalum capacitors.

7.Wide Operating Temperature Range: They can function over a broad temperature range, from -55°C to over 125°C.

8.Low Leakage Current: They generally have low leakage current, which is important for applications requiring minimal energy loss.

CA35 series  (125°C) Hermetically Wet Tantalum Capacitors use in these applications:

1.Aerospace and Defense: These capacitors are used in avionics, radar systems, and space applications due to their high reliability and performance in extreme conditions.

2.Medical Equipment: Wet tantalum capacitors are employed in life-support systems, implantable devices, and other critical medical electronics, where reliability is essential.

3.Oil and Gas Industry: They are used in downhole drilling equipment, where high temperatures and harsh conditions demand capacitors with excellent thermal stability and reliability.

4.Power Supplies: In high-performance power supply units, these capacitors help to filter and smooth voltage, ensuring consistent and clean power delivery.

5.Telecommunications: Used in high-reliability communication systems where long operational life and stable performance are crucial.

6.Industrial Equipment: Applications such as robotics, heavy machinery, and other industrial systems benefit from their high reliability and ability to withstand harsh environmental conditions.

CA35 series  (125°C) Hermetically Wet Tantalum Capacitors advantages:

Long Life: Hermetically sealed capacitors last longer than their non-sealed counterparts.

High Performance: Superior performance in high-temperature, high-pressure, and high-stress environments.

High Capacitance-to-Volume Ratio: These capacitors provide higher capacitance in smaller packages than many other technologies.

Tantalum capacitors Disadvantages:

Cost: Wet tantalum capacitors are generally more expensive than standard electrolytic or ceramic capacitors due to the materials and processes involved.
Size: Compared to some other capacitor types, they may be larger for equivalent ratings.
