Tantalum-Polymer capacitors (Ta-Poly C’s) are gaining popularity in the electronics industry as they offer a cost-effective solution for bulk capacitance storage applications with improved performance potential. The T540B157M003AH8610WAFL is a 10µF, 16V, safety certified, conformal-coated molded SMD tantalum capacitor. It is designed to provide reliable electrical performance over wide temperature ranges while meeting application-specific requirements such as board-level system-level performance.

A Ta-Poly C uses a polymeric material as its dielectric, which generally allows for lower ESR value compared to standard tantalum capacitors.

T540B157M003AH8610WAFL is a molded surface-mount tantalum polymer capacitor with a high temperature rating for use in applications such as power management and signal processing where board-level temperature extremes from -55.. +125°C may be encountered. The T540B157M003AH8610WAFL is compliant with safety agency recognized safety standards including safety certification ratings such as UL, CSA and IEC. They offer good performance up to frequencies of over 1MHz and with no breakdown voltage derating. It also meets industrial standards such as ESCC, CECC and MIL standards.

The T540B157M003AH8610WAFL also supports Automatic Insertion, Automatic Placement and Automatic Termination. Electrostatic discharge immunity has been tested and meets the requirements of IEC 61000-4-2 (Level 3). Its chip form allows for high reliability mounting while its conformal coating provides superior protection against moisture, humidity, and other corrosive environments. It also offers only 1mm of additional space to fit larger components after attachment and is RoHS compliant for lead-free operation.

The T540B157M003AH8610WAFL features robust operation and differs from traditional tantalum capacitors in that it utilizes a different dielectric material due to its improved capacitance stability over temperature and higher capacitance value. This improved stability and higher capacitance makes it ideal for a wide range of applications requiring high capacitance value and improved capacitance stability. There are various application fields in which Ta-Poly Cs such as the T540B157M003AH8610WAFL can be found including, but not limited to, automotive industry, parallel switching/merging and audio/video in home entertainment systems.

The working principle of Ta-Poly Cs, such as T540B157M003AH8610WAF, is similar to conventional tantalum capacitors. The capacitance value is derived from the area of the plate and the spacing between them, with the polymeric dielectric material holding the charges in place. When a voltage is applied, an electric field is created, which causes electrons to flow from one plate to the other, forming an electrical current. The capacitance is then determined by the amount of charge (electrons) stored on each plate per unit voltage. This is known as the capacitance leakage current and its magnitude is inversely proportional to the area of the plates and the thickness of the dielectric layer.

Most Ta-Poly Cs, such as the T540B157M003AH8610WAFL, can offer over 10,000 hours of life in extreme temperature applications with lifetimes of over 1 million hours guaranteed at room temperature. This is because Ta-Poly Cs have an improved resistance to aging effects due to the improved stability and fewer migration issues that can occur in older temperature dependent capacitors.

Therefore, the T540B157M003AH8610WAFL is an ideal solution for high capacitance storage applications in various industries that require increased performance potential and improved capacitance stability. It is a cost-effective solution for a variety of applications and its compatibility with SMD mounting and its safety certification ratings makes it a perfect choice for applications where protection against extreme temperatures, humidity and other environmental conditions is needed.
