What is a MELF resistor?
MELF resistors consist of a homogeneous film of metal alloy deposited on a high-grade ceramic body. Nickel- plated steel termination caps are pressed on the metalized rods, before a special laser cuts a helical grove in the resistive layer to achieve the target resistance value.
What is a Vishay resistor?
Vishay’s discrete resistors serve applications in virtually all major market sectors. Vishay is the number one manufacturer worldwide of wirewound and other power resistors, leaded film resistors, and thick film surface-mount resistors.
How to measure smd resistor size?
The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the width and height of the package. So, the imperial code 0603 indicates a length of 0.060″ and a width of 0.030″.
What sizes do resistors come in?
SMD resistors come in standardized sizes; usually either 0805 (0.08″ long by 0.05″ wide), 0603, or 0402. They’re great for mass circuit-board-production, or in designs where space is a precious commodity.
What is Mel F?
Metal electrode leadless face (MELF) is a type of leadless cylindrical electronic surface mount device that is metallized at its ends. MELF devices are usually diodes and resistors.
When would you use a MELF resistor?
MELF, Metal Electrode Leadless Face resistors are used where higher reliability and performance than that provided by normal SMT resistors are needed.
What is a through hole resistor?
A through-hole resistor is a fixed resistor that has long, pliable leads that can be stuck into a breadboard, or hand- or wave-soldered into a printed circuit board (PCB). Also known as a leaded resistor, a through-hole resistor is used to reduce the flow of electrical current within a circuit.
Where are Vishay resistors made?
Vishay has manufacturing plants in Israel, Asia, Europe, and the Americas where it produces rectifiers, diodes, MOSFETs, optoelectronics, selected integrated circuits, resistors, capacitors, and inductors. Vishay Intertechnology revenues for 2018 were $3.035 billion….Vishay Intertechnology.

What is the highest resistor value?
714 K
The total range of possible resistances is almost 100K. The fourth resistor’s nominal value is 680 K. Performing the same process with tolerances, we find that the highest possible value is 714 K while the lowest possible value is 646 K.
What is resistor?
Resistor is defined as an electrical component which is used for controlling temperature and voltage. There are two types of resistors: linear resistor and non-linear resistor. Resistors are identified with the help of color codes. Resistor finds application in demodulator.
What are the sizes of the MELF resistors?

What is the size of an SMD resistor?
The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the width and height of the package. So, the imperial code 0603 indicates a length of 0.060″ and a width of 0.030″.
What is the standard size of a surface mount resistor?
The shape and size of surface mount resistors are standardized, with most manufacturers using the JEDEC standards. The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the width and height of the package. So, the imperial code 0603 indicates a length of 0.060″ and a width of 0.030″.
