Tantalum capacitors, or “Tant caps”, are a type of conductive electrolytic capacitor — they offer good performance in applications where size and capacity are key components. The T540D477M004BH86107610 is one such tantalum capacitor, offering good capacitance and resistance in a small, lightweight package. This article will discuss the application field, working principles, and characteristics of the T540D477M004BH86107610.

Application Field for the T540D477M004BH86107610

The T540D477M004BH86107610 offers an excellent choice for a range of applications, particularly in audio applications or when high capacitance and small size are required. As it is a surface-mounted capacitor, it is suitable for printed circuit boards and other compact designs, where its compact form factor and good dissipation ability help to optimize the system. It is also robust and resilient, making it an ideal choice for military, avionics, and industrial grade applications. With high ripple current and low equivalent series resistance, the T540D477M004BH86107610 is also suitable for power decoupling, voltage stabilization, energy storage, and high-frequency filtering.

Working Principles

At its most basic, the T540D477M004BH86107610 is a capacitor composed of a Ta (tantalum) anode and a polymer cathode, separated by an electrolyte. It utilizes the fact that when electrical current passes through the electrolyte, it forms an electric charge which accumulates on the capacitor plates as they polarize. This charge is then used to store electrical energy in an electrical field.

The T540D477M004BH86107610 utilizes an anodic layer at the center of the capacitor plate. This layer is made of Ta and serves to provide additional electrical insulation when the external voltage is applied. It also helps prevent degradation of the capacitor due to dendrite formation, which can occur when a pure electrolyte solution is used. This improved construction helps to improve its overall performance.

Characteristics and Specifications

The T540D477M004BH86107610 has a capacitance range of 47-540µF, with a maximum working voltage of 10Vdc. It has an operating temperature range of -55°C to +125°C, and a capacitance tolerance of ±20%. Its total case height is 4.3mm, with a diameter of 6.1mm. The dielectric strength is measured at 25VDC for 30 minutes, with an ESR value of 2.4 ohms. It has a maximum ripple current rating of 240mA, and a typical equivalent series resistance (ESR) of 2.7 ohms.

The T540D477M004BH86107610 is a RoHS compliant product, making it a safe and reliable choice for applications requiring restricted use or disposal of hazardous materials. It also has an industry-leading shelf life of up to 10 years, making it one of the most reliable tantalum capacitors on the market.

The T540D477M004BH86107610 is an excellent choice for applications requiring high capacitance and low size. With its robust construction and impressive performance characteristics, it is suitable for a wide range of applications — from audio to military grade. Its high ripple current, low ESR, and RoHS compliance make it a safe and reliable choice.
