What is the difference between alloy resistance and chip resistance?

Alloy resistance is a kind of resistance that uses alloy as current medium. It usually has the characteristics of low resistance, high precision, low temperature coefficient, resistance to impulse current, and high power. It is often used in various electronic products and used in current sampling or short-circuit protection.

The main material of the alloy is copper, and other materials have become constantan, manganese copper and so on. There are many other auxiliary materials, but the main performance is determined by the alloy material itself.

The often mentioned chip resistors generally refer to common types of chip thick film and thin film resistors.

Compared with thin films, thick films are classified from the perspective of materials and processes;

A resistor may be both a thick film and a patch, that is, a patch resistor is made by a thick film printing process,


Of course, thick film printing can also be used to make thick film hybrid circuits, and chip resistors can also be made using thin film technology.

In terms of price: the price of alloy resistors is about 0.1-0.2 yuan. The larger the package body, the more precise the precision and the more expensive the price.

The price of thick film resistors ranges from low to expensive. It is also distinguished by packaging and accuracy.

The precision of alloy resistors is much more accurate than thick film resistors. The precision of thick film resistors is usually between 1% and 5%, and alloy resistors can reach below 1%.
