1.5K Ohm 1/4w Film Resistor - Pack of 10

The 1.5K Ohm 1/4W Film Resistor – Pack of 10 is a useful collection of fixed resistors designed for general-purpose electronics applications. Each resistor has a resistance value of 1.5 kilo-ohms (1.5KΩ or 1500Ω) and a maximum power rating of 0.25 Watt (1/4W).

Resistors are among the most commonly used components in electronics. They are essential for controlling electrical current, dividing voltages, setting signal levels, and protecting LEDs and other sensitive components.

This pack includes 10 pieces, making it convenient for electronics students, hobbyists, makers, and engineers.

1.5K Ohm Resistance Value

The resistance value of each component is:

1.5KΩ = 1500Ω

The "K" represents kilo, meaning one thousand.

Therefore:

• 1KΩ = 1000Ω
• 1.5KΩ = 1500Ω

A 1.5K resistor can be used in many circuit designs depending on the required current and voltage.

1/4 Watt Power Rating

This resistor has a 1/4 Watt (0.25W) power rating.

The power rating indicates the approximate maximum power the resistor is designed to dissipate under appropriate operating conditions.

When designing a circuit, ensure that the resistor power dissipation remains within its rated limit.

The power dissipated by a resistor can be calculated using:

P = I²R

or:

P = V² / R

Where:

• P = Power in Watts
• I = Current in Amperes
• R = Resistance in Ohms
• V = Voltage across the resistor

For reliable operation, avoid operating a resistor continuously at or beyond its maximum rated power.

Fixed Film Resistor

This product is a fixed-value film resistor.

Film resistors are widely used in electronic circuits because they are suitable for general-purpose applications and are easy to install on breadboards and PCBs.

They are commonly used in:

• Educational circuits
• DIY electronics
• PCB designs
• Prototyping
• Electronic repairs

Through-Hole Design

The resistor features a traditional through-hole design with two leads.

This makes it easy to use with:

• Breadboards
• Perfboards
• Prototype boards
• Printed circuit boards
• Hand-soldered circuits

The leads can be inserted into a breadboard or soldered directly onto a PCB.

Ideal for Breadboard Projects

The 1.5K Ohm resistor is suitable for breadboard prototyping.

It can be used while experimenting with:

• LED circuits
• Transistor circuits
• Sensor circuits
• Microcontroller projects
• Voltage divider circuits

Its standard through-hole design makes it convenient for repeated use during prototyping.

Suitable for Arduino and ESP32 Projects

This resistor pack is useful for microcontroller-based projects involving:

• Arduino
• ESP32
• ESP8266
• STM32
• Raspberry Pi-compatible electronics
• Other development platforms

A resistor may be required for pull-up, pull-down, current limiting, or signal conditioning depending on the circuit design.

LED and Current Limiting Applications

Resistors are commonly used to control current flowing through LEDs.

A suitable resistor value must be selected according to:

• Supply voltage
• LED forward voltage
• Desired LED current

The 1.5KΩ resistor may be suitable for certain low-current LED circuits, but the correct value should always be calculated based on the specific application.

Voltage Divider Circuits

The 1.5K resistor can also be used as part of a voltage divider circuit.

A voltage divider typically uses two resistors to create a lower voltage from a higher input voltage.

The output voltage depends on the ratio between the resistor values.

This is useful for:

• Analog signal conditioning
• Sensor circuits
• Microcontroller input circuits
• Voltage measurement applications

How to Identify a 1.5K Ohm Resistor

The exact colour bands may depend on the resistor type and tolerance.

For a common 4-band resistor with a standard tolerance, 1.5KΩ may typically be represented by:

• Brown
• Green
• Red
• Tolerance band

Always verify the resistance value using the colour code or a multimeter when necessary.

Important Notes

• Resistance value: 1.5KΩ (1500Ω)
• Power rating: 1/4W (0.25 Watt)
• Do not exceed the resistor's rated power.
• Resistor tolerance may vary by manufacturing batch.
• Physical size and colour may vary.
• The exact film material may vary depending on the supplied product.
• Always verify component specifications for critical applications.
