Introduction

Tantalum capacitors (or tantalum-based capacitors) are a type of electrolytic capacitor, a passive two-terminal electrical component consisting of two conducting plates and an electrolyte, designed for use in electronic circuits. Tantalum capacitors offer a variety of advantages over other capacitor types, including low ESR (equivalent series resistance), low leakage current, high-temperature stability, and high capacitance. The M39003/01-3139/HSD is a series of solid tantalum capacitors designed by Vishay Intertechnology for high-reliability, high-frequency, and long-term operation.

M39003/01-3139/HSD Design and Capabilities

The M39003/01-3139/HSD series is a range of solid tantalum capacitors, featuring a case size of 4.70mm x 5.80mm. The capacitors are fortified with a glass-to-metal seal to protect them from moisture and other contaminants, and are designed for use in a wide range of environments, including extreme temperatures and radiation exposure. The M39003/01-3139/HSD series is rated for an operating voltage range of 1.5V to 33V and capacitances from 0.47 μF to 470 μF. The series also includes a ESR rating range of 0.08 mΩ to 30 mΩ@50Hz. The M39003/01-3139/HSD series is available with a variety of termination finishes, including gold, tin-silver-copper, and matte tin. The series is also rated for a temperature range of -55°C to +125°C and a maximum peak current of 3A (with a duty cycle of 1% max). In addition, the capacitors feature a low equivalent series resistance (ESR) and low leakage current, making them ideal for applications that require high frequency and long-term operation.

M39003/01-3139/HSD Application Field and Working Principle

The M39003/01-3139/HSD series is designed for use in high-frequency circuits with long-term repetitive operations. The capacitors are ideal for use in automotive, telecommunications, defense, aerospace, and medical electronics applications. The capacitors are useful in a variety of circuits, including noise filtering, voltage conversions, signal processing, power supplies, DC-DC converters, and specialized signal-isolation circuits. The capacitors are also suitable for use in circuits that require temperature tolerance, high-frequency stability, and radiation hardening. The working principle of the M39003/01-3139/HSD series is based on the two-terminal "dielectric" capacitor design, where one terminal serves as the anode, and the other the cathode. In this design, a thin film of an insulating material, called the dielectric, is inserted between two plates. When a voltage is applied, an electric field develops across the dielectric, enabling the capacitor to store energy. By increasing the surface area of the plates, or by decreasing the thickness of the dielectric, the capacitance of the capacitor can be increased. The M39003/01-3139/HSD series utilizes an electrolyte to increase the capacitance even further for a given size of capacitor.
