39 Ohm 1/4 Watt Resistors (10 Pieces) Pack

The 39 Ohm 1/4 Watt Resistors (10 Pieces) Pack contains ten high-quality fixed-value resistors designed for controlling current flow, dividing voltage, and protecting sensitive electronic components in a wide range of electronic circuits. Each resistor has a resistance value of 39 Ohms (39Ω) and a power rating of 1/4 Watt (0.25W), making it suitable for low-power electronic applications such as LED circuits, Arduino projects, embedded systems, educational experiments, circuit prototyping, and electronic repairs.

A resistor is one of the most essential passive components in electronics. Its primary function is to oppose the flow of electric current, helping to regulate current levels and create controlled voltage drops within a circuit. By limiting excessive current, resistors protect sensitive components such as LEDs, transistors, integrated circuits, sensors, and microcontrollers from damage caused by overcurrent conditions.

The 39 Ohm resistor is commonly used in current-limiting circuits, voltage divider networks, transistor biasing circuits, pull-up and pull-down resistor networks, signal conditioning applications, and power management circuits. It is available in carbon film or metal film construction, providing stable resistance values, low electrical noise, and reliable long-term performance.

These resistors feature a through-hole axial lead design, allowing easy installation on solderless breadboards, printed circuit boards (PCBs), stripboards, and prototype boards. The leads are easy to solder, making them suitable for both beginners and professional electronics engineers. Standard resistor color bands are provided for quick and accurate identification of the resistance value.

With a power dissipation rating of 0.25 Watts, these resistors can safely handle typical low-power applications while maintaining consistent electrical performance. The pack of 10 resistors offers excellent value for students, hobbyists, repair technicians, and engineers working on multiple electronics projects.

Working Principle

A resistor works by resisting the flow of electrical current.

• When current passes through the resistor, part of the electrical energy is converted into heat.

• The resistor limits current to safe levels for connected components.

• It creates controlled voltage drops where required.

• It helps stabilize circuits and ensures reliable operation of electronic devices.
