RND Electrical and Electronic Components used in Industrial Applications

Sourcing electronic components consumes a lot of an engineer’s time. There are typically several vital factors that influence the final choice. Subtle differences in a product’s specification, performance and price can make selecting components a challenging task. This is why focusing on what components can offer overall across its entire lifespan is critical. For example, components offering higher than required performance but also at a higher price may not be the best overall offering. Components that are fit for purpose at a much more economical price makes much more sense.

This is where a brand like RND comes into its own, providing an extensive product portfolio for maintenance technicians and engineers. RND offers a wide range of high-quality electronic products and components at reasonable prices.

Electronic component sourcing

Look inside any piece of modern electrical equipment, and you’ll find a variety of electronic components. If you peer at the printed circuit boards, you may see a number of complex and sophisticated processing integrated circuits, known as ‘ICs’ or ‘chips’. These ‘chips’, such as microcontrollers (MCUs), field-programmable gate arrays (FPGAs), and graphics processing units (GPUs), provide the machine’s digital processing capabilities. However, the vast number of components you’ll see are passive components, such as resistors, capacitors, and inductors. But let’s not also forget the crucial hardware items, including connectors, ferrules, enclosures, and LED panel indicators.

Whether specialised or commodity, every component must be accounted for on a bill of materials (BOM) and needs sourcing. Together, everything on the BOM makes the product function, but equally as important is the product’s reliability and longevity of operation. To comply with regional and international safety standards, the internal workings of the equipment must also conform to stringent standards and requirements. In short, a high degree of trust is needed in components to deliver a high degree of reliability and that they meet all relevant technical and safety standards.

Industrial components selecting guidelines

The easiest way to choose the right electronic or electrical equipment is to use already proven devices. Being familiar with the designs will save you time and effort. However, you can miss out on the advantage of new parts with that in mind. Some newer devices offer much better efficiency, ease of integration and often a more affordable price.

Choosing new parts that haven’t previously been sourced might be problematic. This is why validating products, to ensure that are fit for purpose, is really important before making any selection.

Manufacturers

Devices keep changing, and it is good to keep up to date with the latest technologies and specifications. Manufacturers might enhance and even change some component speciation’s over time without prior notice. This makes selecting manufacturers and brands that provide datasheets, reference designs and application notes very important.

Quality

Out of the thousands of products available from plenty of manufacturers, suppliers, and distributors, it is difficult to find the right equipment that will be affordable and high-quality. RND products offer genuinely great value to engineers wishing to buy competitively priced, high-quality components that offer efficiency and longevity of performance across the entire lifecycle.

Electrical parameters

Electrical parameters, specifications and section criteria will usually differ according to the product being sourced. For example, for a DC-DC converter IC, you have to consider: voltage range, output voltage accuracy, over and under voltage, thermal shutdown, power rating, inbuilt protections, light load efficiency, thermal management, etc.

PCB package

A PCB package aims to describe numerous parameters of actual electronic components graphically. It shows the component size, length and width, in-line, patch, pad size, pin length and breadth, pin spacing, etc. These parameters may be referred to when constructing a PCB diagram. It is important to know the PCB footprint, especially if you order something to fit in on the board and is too big or too small.

Costs

Sourcing components that are attractively priced, particularly those that are required in large numbers, ensure the manufacturer maintains profit margins and their end-products are commercially viable. Choosing RND products from Distrelec guarantees access to low-cost components without compromising on quality.

Fuse

A fuse is a material or a piece of wire that protects components from being destroyed by too much current flowing through them. When an excessive amount of current is passed through a circuit, the wires become hot and damaged. As a result, the current comes to a halt. When a fuse melts owing to an overload of current, the fuse element absorbs some of the energy. The RND 5 x 20 Fuses have quick blow (F) IEC60127-2/2, nickel-plated end caps, and are UL approved, E492698.
