Package List: 1 x SMD Resistor Sample Book(170 value, 25pcs each, 4250pcs in total) Note: 1. Before using the resistance, use a multimeter to measure the resistance, and it can be used after checking.2. The choice of the size of the error, the selection of chip resistors is generally ±10% of the value of the circuit diagram.3. Selection of rated power, choosing high‑power chip resistors will increase the volume and increase the cost, which is not conducive to the design of the circuit.
