Product Certification

This article explains the saga of having electronic products certified for sale.   In order to be able to sell a piece of electronic equipment or device in a country, various certifications may be required to be acquired as per the appropriate governing regulations set by that country. Each country may mandate compliance with its own set of standards which would form a large stockpile of documents. However in most cases, such standards are derived from or are variations of a more internationally recognized standard such as the one laid out by the IEC (International Electrotechnical Commission). An example is the BS EN 55024, a British Standard that lays down the limits ...

Golden Rules for Electronic Circuit Design

This short article presents a concise checklist of rules that must be followed for an electronic design to be successful. Ascenten ensures that all of its designs conform to the following guidelines:

• All components must conform to the specified temperature range. For resistors, de-rating of power rating at peak temperature must be considered. For capacitors de-rating of capacitance, leakage and increase in ESR at peak temperature may be important. For other components such as diodes and transistors, parameters such as recovery times and current gain vary with temperature and must be considered at extreme temperatures. In summary, no design calculation must be left to chance (as is often the
