Panasonic — Understanding Hybrid and Polymer Capacitors

FTMSept2018-DN-Panasonic-tile-200x200

Specifying capacitors might seem a simple task, but it has actually become more complicated in recent years. The reason is growing freedom of choice. The universe of capacitors has expanded greatly over the past few years, in large part because of the new capacitor technologies which have provided many advances in conductive polymer solutions. These […]

Renesas — Dual-Protocol Transceivers Simplify Industrial PC Interfaces

FTMSept2018-DN-Renesas-DualProtocol-tile-200x200

The trend in industrial PC designs towards smaller form factors and more communication versatility is driving the development of modern bus transceivers. New transceivers are favored over legacy designs because of their high level of integration, dual-protocol capability supporting the RS-232 and RS-485 standards, and ample configuration features. Developed in the early 1980s, the RS-485 […]

Renesas — How to Protect Buck Regulators from Over-Current Damage

FTMSept2018-DN-Renesas-tile-200x200

A synchronous buck regulator will often be used in an industrial application to step down 12V rails to point-of-load inputs, sometimes supplying a voltage as low as 0.6V to a microcontroller, FPGA, memory IC or peripheral I/O. In these cases, Over-Current Protection (OCP) is necessary to protect the switching regulators from damage caused by excessive […]

Vishay — Apples to Apples? Considerations When Substituting Polymer and Tantalum Capacitors for MLCCs

FTMSept2018-DN-Vishay-tile-200x200

By Craig Hunter, Senior Director, Global Marketing Communications and Dave Richardson, Senior Manager of Field Applications, Vishay Intertechnology OEMs are today suffering from shortages of Multi-Layer Ceramic Capacitors (MLCCs), especially for devices in large case sizes and in high capacitance values. This has led them to evaluate the polymer tantalum capacitor as an alternative for […]
