The M39003/01-5087H is a tantalum capacitor, which is a type of electrolytic capacitor characterized by extraordinarily high capacitance relative to its volume. This capacitor is commonly used in the application of audio and high-frequency-signal filtering, and its ability to provide low impedance at both low and high frequency signals makes it an ideal choice for applications like these. In this article, we’ll discuss the details of the M39003/01-5087H including its manufacture, application field, working principle, and selection criteria.

The M39003/01-5087H utilizes automated tape and reel for production. This capacitor is a molded micro-surface-mount tantalum with a CV range of 30µF to 270µF and a tolerance of ±20%. It has an operating temperature range of -55°C to +125°C, and it is available in a wide variety of package sizes and case styles ranging from 0603 to 1812 in size. Depending on the application, the M39003/01-5087H can be provided with an epoxy conformal coating for top insulation.

The M39003/01-5087H’s application includes automotive, medical, consumer, and industrial applications requiring low distortion and high reliability. Its low ESR and high ripple current capability make it ideal for these applications. The capacitor can also be used in DC-to-DC converters, signal distortion free switches, power supply bypassing, and timing circuits, as well as for filtering and energy storage.

The working principle of the M39003/01-5087H is relatively simple, yet highly effective. It has a sliver of anodic oxide, usually made from tantalum, which is used as the dielectric material. When voltage is applied to the capacitor, positive charge accumulates on one side of the anodic oxide dielectric layer while negative charge accumulates on the other. This induced charge creates a field of electrostatic repulsion that resists changes in the voltage across the capacitor. This helps keep the voltage stable, and thus is necessary for proper operation.

When selecting a M39003/01-5087H, there are a few factors to keep in mind. Firstly, consider the application and its requirements. Opt for higher CV values for applications that require stable power supply or audio filtering. Secondly, pay attention to the case size. The case size impacts the amount of space available. Last but not least, look for one with a higher temperature rating if your application is operating in a high temperature environment.

In summary, the M39003/01-5087H is a high-performance bipolar tantalum capacitor that is well-suited for a wide range of applications. It has low ESR and high ripple current capabilities, making it ideal for applications such as DC-to-DC converters, signal distortion free switches, power supply bypassing, and timing circuits. Looking for a higher temperature rating, larger CV values, or a smaller case size can further help refine your selection.
