Know before you buy
Yes, the extra thick copper leads are designed for durability and provide a secure fit in standard solderless breadboards, making them ideal for rapid prototyping.
Each of the 140 resistance values is individually packaged and clearly labeled, which helps you quickly locate the exact component you need without having to decipher color codes.
These are 1/4 Watt (0.25W) metal film resistors with a 1% tolerance, providing the precision and power handling required for most general electronics projects.
The kit contains 1400 pieces in total, with 10 individual resistors provided for each of the 140 distinct ohm values.
These are metal film resistors, which are generally preferred for their lower noise levels and better stability compared to carbon film alternatives.
