Product Introduction

Metal film precision resistor is formed by using high-temperature vacuum coating technology to tightly attach nickel chromium or similar alloys to the surface of a ceramic rod to form a film. After cutting and adjusting the resistance value, the final required precision resistance value is achieved. Then, appropriate joints are added and cut, and epoxy resin is coated on its surface for sealing protection. Due to its lead type resistor, it is convenient for manual installation and maintenance and is used in most household appliances, communications, and instrumentation.

main features

1. Compared to precision plug-in resistors and wire wound resistors, it has a compact and exquisite appearance. If it is used for some small-sized products, it will save a lot of space. The consistency of soldering on the surface mount machine is good, and the efficiency is high.
2. The highest accuracy can reach 0.01%, and the lowest temperature coefficient can reach 5PMM.
3. The size range is wide, with a minimum of 0201 and a maximum of 2512.
4. High cost-effectiveness, about twice as cheap as cylindrical metal film resistors of the same specifications, and even more in some specifications.

Suggestions for using resistors

It is best to leave 1.5 times the power margin for resistors in circuits. For example, if the voltage in the circuit is 100V and the current is 0.01A, the calculated power P=100 * 0.01=1W. At this time, a resistor of 1W cannot be used, and 1 * 1.5=1.5W is calculated. If there is no 1.5W resistor, a resistor of 2W is needed.
Resistors should not exceed their maximum operating voltage during use
