Customer Questions & Answers
What are the main advantages of the metal film resistors in this pack compared with traditional carbon resistors?
Metal film resistors offer greater precision (±1% tolerance versus ±5% for carbon resistors), better thermal stability and lower electrical noise. This makes them preferable in electronic applications where accuracy and reliability are required, although they are usually slightly more expensive.
What electrical and physical parameters should I consider to install them correctly on a circuit board?
Each resistor is rated at 1/4 W (0.25 W) maximum power and supports a typical maximum voltage of 200–250 V depending on the application. The body measures approximately 6.3 mm long and 2.3 mm in diameter, with 0.5 mm leads. Make sure not to exceed the rated power and respect the pin spacing on the board.
Are these resistors compatible with 3.3 V and 5 V microcontroller projects, and what limits should be considered?
Yes, they can be used directly in 3.3 V and 5 V circuits as long as the power dissipation (P = V^2 / R) does not exceed 0.25 W per resistor. For very low ohm values or applications involving high currents, check the dissipation calculation before integrating them.
In terms of durability, how do factors such as ambient temperature or oxidation affect the accuracy or lifespan of these resistors?
Metal film resistors usually have a low temperature coefficient (±50 ppm/°C), so they maintain their value across ranges from -55°C to 155°C. However, prolonged exposure to damp or corrosive environments can damage the leads. We recommend storing them in a dry place and mounting them in accordance with IPC standards for maximum durability.
What type of resistors does this pack include?
It includes metal film resistors with a rated power of 1/4 watt and 1% tolerance.
How many resistors and different values are in the pack?
The pack contains a total of 1220 resistors, arranged in 122 different values, with 10 units per value.
What applications are these resistors recommended for?
They are ideal for electronics projects, repairs, prototypes and as a replacement for 1/4W carbon resistors with 5% tolerance.
Are the resistors labelled?
Yes, each resistor is labelled to make identification and use in circuits easier.
What is the resistance value range in this pack?
The values range from 0.1 Ohm to 4.7M Ohm, covering a wide variety of needs.
