Tantalum capacitors come in two basic varieties: solid types (SMD) and wet or electrolytic types (Case leaded or Chassis mounting). The TPSD687M004R0045 is a solid type tantalum capacitor. It is a single anode, non-polarized device, meaning that no polarity is necessary for operation. It has a rated capacitance of 4.7 µF and a rated voltage of 16 VDC. The device has a maximum operating temperature range of -55°C to +125°C.

The TPSD687M004R0045 is commonly used in a variety of applications, ranging from filtering and decoupling to power supply smoothness and television set noise suppression. Its non-polarized design allows for standard use in AC circuits, and it is suitable for oscillators, filters, and any circuit where a low-cost capacitor is necessary. It is also ideal for industrial applications, as it has an extremely high melting point (3,000 °C) that exceeds that of most other capacitors.

The TPSD687M004R0045 is a self-healing device, meaning that it automatically repairs itself if it is ever damaged due to over-voltage or external shocks. The source of the mechanical damage is "blown" away as a portion of the dielectric material is ejected in the form of a gas. This process allows the TPSD687M004R0045 to operate reliably again.

The working principle of the TPSD687M004R0045 is that of a polarized capacitance. The device consists of two layers of tantalum pentoxide, separated by a spacer material. A voltage applied across the device causes charge to accumulate on the individual layers, which acts to store electrical energy as electrostatic potential between the two plates. This stored energy can later be released when the charge carriers move back to their original positions. The voltage-capacitance (V-C) characteristic is described by the equation C = εA/d, where ε is the dielectric constant of the material, A is the area of the plates, and d is the spacing between them.

As with all capacitor types, the TPSD687M004R0045 has associated characteristics such as low leakage current, high insulation resistance, high frequency performance, and low ESR (Equivalent Series Resistance). The device also offers other advantages, such as good thermal stability, low noise generation, good stability over long life, and RoHS compliance. In addition, the solid construction of the TPSD687M004R0045 makes it extremely durable and has led to widespread demand for the device in both commercial and military applications.

In summary, the TPSD687M004R0045 is a single anode, non-polarized, solid type tantalum capacitor, with a rated capacitance of 4.7 µF and a rated voltage of 16 VDC. It has a wide range of applications and offers advantages such as low leakage current, high insulation resistance, and RoHS compliance. The device has a self-healing characteristic, along with good thermal stability, low noise generation, and good stability over long life. As such, the TPSD687M004R0045 is an ideal solution for a variety of applications, from filtering and decoupling to power supply smoothness and television set noise suppression.
