NettetSmaller power-resistors are often used to sense current. The power ratings of surface mount resistors can usually be judged by their size as well. Both 0402 and 0603-size resistors are usually rated for 1/16W, … Nettet11. okt. 2024 · The resistance value for a pull-up resistor is not usually that critical but must maintain the input pin voltage above V IH. The use of 10kΩ pull-up resistors are common but values can range from 1k to 100k ohms. Pull-down resistors are a little more critical because of the low input voltage level, V IL(max) and the higher I IL current.
