Dec 31, 2017 Forum for software engineering and programming. A collection of completed projects from All About Circuits forum. Datasheets; Electronic Components; Forum. A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other technical characteristics of a product, machine, component (e.g., an electronic component), material, a subsystem (e.g., a power supply) or software in sufficient detail to be used by a design engineer to integrate the component.

Date: 16-02-17 The Principles and Process of Electronic Component Selection (part-5) Component Selection: 'an art' for SMART and Cost-effective Designs Electronics components are the major part of the electronics system design and are rapidly undergoing technology advancements both, in performances and sizes. Obviously, the successful companies and products have utilized 'smarter' components in their designs. Windows 7 Faxcool Activator Boats.

The method of choosing such 'smart' components thus becomes 'an art' to be acquired by the engineers today. It appears as if the process of component selection for the hardware design requirements is very simple and straightforward but indeed there are many considerations and 'techniques' involved behind.

An error made in the component selection can cause serious damages up to an extent of thrashing and disqualifying the entire design and the product. So, utmost care and precautions are advisable while performing this activity. Gendex Gx 770 User Manual. Hence in most of the organisations, a dedicated team of component engineers are formed to help the design teams. The component engineers need to have the breadth of knowledge and experience in the fundamental understanding of components, their specifications, constructions, and functionalities.

The component engineer is the one who is approached for the selection of components and suppliers since he acts as the liaison between sourcing/supply chain, design and, manufacturing teams as well as strengthens the supplier relationship. Choosing the right component is the most important task involved in the product development cycle because a wrong selection here creates heavy and unpredictable losses (money, machine, men, time, etc.,) throughout the development activities causing failures and delays in the product releases. Even though the technology advancements, e-commerce and globalisation have made the engineer's life easier, the human interference and intelligence are still very much essential in one or the other form. Utilizing the web-based parametric tables and other user-friendly methods to select a component is easy but one should know how, when and where to use them appropriately. There are reference component databases available in the market, both free and subscription-based.

However, these databases may take the engineer to the nearest set-of-components but choosing the best one that suits the design is still the selector's task. There are various parameters such as electrical, mechanical, environmental, cost, reliability factor, availability (life cycle), etc., which should, at a minimum, be considered while selecting a component. Component selection is a process of selecting a suitable component or a set of similar components from different suppliers for the designed circuit to perform its intended operation. The component engineer may have to first understand the circuit functionality or has to get the exact parametric values with the permissible tolerance levels for each parameter from the design engineer. The component engineer has to volunteer in gathering as many details as possible from the design engineer in order to speed up the component selection. Most of the times, the design engineer invariably provides the list of critical parameters alone, but for the component engineer, the other non-listed parameters are also critical. Hence it's important for the component engineer to query the design team even for a small doubt and not to guess or consider the attribute values for granted.

The component engineer should also consider the 'underlying factors' or the 'competitive edge' of the component when compared with the nearest competitors. Due consideration should be given to the affordability - a factor that guides the company to prefer an expensive component to avail the additional features, become more competitive and reap the most out of the investment made. Here a line of compromise is drawn and compared between the investment made and the return on the investment while choosing the technology-based competitively-edged components. Mere choosing the right component is just not sufficient for product development but to track and control every component's specifications throughout the supply chain and the product's life cycle is also significant. Many companies implement part-specific and product-specific specification control documents which are updated as and when a change is made with respect to the part or the product.
