RS PRO 4.7Ω 10% 225W Adjustable Wire Wound Resistor 50ppm/°C 21.6mm

RS PRO Vitreous Enamelled Adjustable Resistors

Introducing the range of RS PRO Adjustable Resistors, an ideal solution for applications requiring settings at different resistance values. These reliable wire-wound resistors are easy to fit and durable thanks to the vitreous enamel construction, making them suitable for use in a wide range of environments where adverse or challenging conditions may impact standard adjustable resistors.

Features and Benefits:

• RS PRO adjustable resistors are the ideal solution for resistance management in a wide range of applications


• These resistors are capable of withstanding adverse conditions thanks to the nickel-chrome winding being completely protected by several coats of vitreous enamel fired to create a highly reliable resistor


• They also offer particularly good resistance to thermal shock and leakage, offer high dielectric strength and high mechanical resistance over the complete temperature range


• These adjustable vitreous enamelled resistors are available in a range from 90 Watts to 750 Watts and are supplied with terminal tags suitable for screws or ’Fast On’ terminals on selected sizes


• Supplied with mounting brackets

Applications:

Adjustable or variable wire-wound resistors are a type of passive component used to reduce, restrict and adjust the electrical resistance when working with electrical circuits. The main advantages of these types of resistors are that they offer high accuracy and reliability, but with a low cost and wide resistance range, making them incredibly versatile for use in a range of different applications like:

• Audio and visual equipment


• Computers and telecommunication


• Aerospace, defense and military


• Medical equipment
