Advantages, disadvantages, and application scope of patch film resistors
Surface mount thin-film resistors are ubiquitous in electronic circuits and are one of the essential electronic components in most circuits. Thin film patch resistors use thin film technology to sputter deposit metal resistive thin films (0.2~1 μ m) on ceramic substrates, which are then packaged and manufactured after precise resistance tuning. Thin film patch resistors can be appropriately selected in thickness to create various resistance values, with specific films corresponding to a certain range of resistance values
Advantages of Thin Film Chip Resistors:
High resistance accuracy and low temperature coefficient;
Less loss and low noise;
Low parasitic effects, excellent high-frequency performance;
Chip miniaturization, suitable for SMT process;
Disadvantages of thin-film surface mount resistors:
The thin film of the resistor will oxidize in high temperature, chemical corrosion and other situations, causing the resistance value to constantly change; The resistance film of high resistance thin film resistors is very thin, making them more susceptible to oxidation and resulting in greater resistance deterioration.
The thin film of the resistor is easily affected by ESD electrostatic discharge voltage.
The application range of thin-film surface mount resistors:
Automotive electronics, medical electronics, LED lighting related products, power products, daily household appliances, computer edge office products, large industrial equipment controllers, network equipment, communication products, digital products, etc.
