Tantalum capacitors are used extensively across many application markets and for a variety of purposes. The M39003/03-4015/HSD is a particular type of tantalum capacitor, with a range of various specifications and physical properties. This article will cover the various applications and working principles of the M39003/03-4015/HSD.

What are Tantalum Capacitors?

Tantalum capacitors are electrochemical components with an internally controlled oxide layer of tantalum. Characterized by excellent high temperature characteristics, high stability, small size and low weight, they are used widely in a multitude of applications such as LED lighting, instrumentation, consumer electronics, and aerospace. The tantalum capacitor is constructed with two electrical connections: a positive and negative electrode, referred to as anode and cathode respectively. Connecting the electrodes to a circuit, the capacitor acts as a filter, providing a small amount of energy storage and filtering out high frequency noise from a circuit.

M39003/03-4015/HSD

The M39003/03-4015/HSD is a type of tantalum capacitors manufactured to meet the MIL-PRF-39003 specification. Such capacitors are made specifically for continuous and reliable operation in military or aerospace applications, where robust performance is a must. The ‘HSD’ in the product designation stands for ‘High Surge Dissipation’, which implies that the capacitors are designed with enhanced surge and vibration features that are specific for situations where a capacitor needs to be exposed to acceleration, deceleration, or prolonged vibration.

Application Areas

The M39003/03-4015/HSD capacitors are most suitable for portable electronic devices, due to their small size and lightweight, such as hearing aids, cell phones, laptops, and portable gaming devices. They form an important part of circuits used in consumer electronics, communications, military and aerospace applications. Given the rigid MIL-PRF-39003 specification and the capacitors’ high surge and vibration capabilities, the M39003/03-4015/HSD are ideal for applications such as:

• Power conditioning, voltage monitoring and transients suppression
• Backlighting for automotive and industrial displays
• Circuits requiring very small size capacitors
• Signal filtering, such as in television and radio applications
• High temperature/high shock and vibration types of circuits
• On-board and backplane power distribution
• Power supply circuits for medical and industrial applications.

Working Principle

When a voltage is applied to the M39003/03-4015/HSD capacitor, electrons start to travel through the dielectric material and the capacitance and impedance of the capacitor increases. At this time, a minimum resistance can be measured across the leads of the capacitor, providing a pathway of current that can now flow throughout the circuit. This process helps the capacitor to filter out certain high-frequency noise and to store a small amount of energy.

The capacitor switch off happens when the applied voltage across the capacitor decreases below the holding voltage of the capacitor. At this point, current can no longer flow and the capacitance returns back to its original state. This helps protect the circuit from any unexpected voltage fluctuations and helps maintain the current flow in the circuit in a regulated manner.

Conclusion

The M39003/03-4015/HSD tantalum capacitor is a specifically designed, mil-spec part that provides high surge and vibration dampening for application in military/aerospace applications, as well as in many consumer level electronics. With its small size and lightweight design, it is ideal for portable electronic devices and circuits, such as cell phones, laptops and hearing aids. Its capacitance and impedance increase when a voltage is applied, allowing current to flow throughout the circuit. The switch off process helps protect the circuit from any unexpected voltage fluctuations and helps maintain the current flow in a regulated manner.
