MOKWN Recommendation

Keep a well-stocked resistor kit with common values like 1.8 kΩ to speed up your prototyping. For precise applications, consider using 1% tolerance resistors. For higher power needs, choose a 0.5W or 1W version. Always double-check your circuit calculations to select the right resistor value.
