10K Ohm Resistor (10kΩ) 1/4W 1% – Pack of 10

10K Ohm Resistor (10kΩ) 1/4W 1% Metal Film – Pack of 10

These 10kΩ 1/4W metal-film resistors have a tight ±1% tolerance and are supplied as a pack of 10. Metal-film construction gives better stability and lower noise than carbon-film resistors, so the value stays accurate across temperature changes.

They are most commonly used for pull-up and pull-down resistor for push buttons and GPIO pins, voltage dividers and transistor base biasing. The axial through-hole leads fit standard breadboards, perfboards and PCBs with 0.1″ (2.54mm) spacing.

Features

• Resistance: 10kΩ with ±1% tolerance
• Metal-film construction for low noise and good stability
• 1/4W (0.25W) power rating
• Axial through-hole leads — breadboard and PCB friendly
• 5-band colour code for easy identification
• Pack of 10 pieces

Specifications

• Resistance: 10kΩ
• Tolerance: ±1%
• Power rating: 1/4W (0.25W)
• Type: Metal film
• Temperature coefficient: ±100 ppm/°C
• Colour code (5-band): Brown – Black – Black – Red – Brown
• Mounting: Through-hole, axial leads
• Pack size: 10 pieces

Quick Calculation

• At 5V a 10kΩ resistor draws only 0.5 mA, which is why it is the standard choice for pull-up/pull-down resistors.
• Formula: R = (Supply voltage − LED forward voltage) ÷ desired current.
• Keep power below 0.25W: P = I² × R.

Applications

• Pull-up / pull-down resistors for buttons and GPIO
• I2C bus pull-ups (with 3.3V/5V logic)
• Voltage dividers for ADC scaling
• Transistor base biasing
• Thermistor and LDR sensor circuits

Package Includes

• 10 x 10kΩ 1/4W 1% metal-film resistors

Frequently Asked Questions

How do I identify a 10kΩ resistor by colour code?
These are 5-band 1% resistors. The bands read Brown – Black – Black – Red – Brown (the last brown band means ±1% tolerance).

What is the difference between metal-film and carbon-film resistors?
Metal-film resistors have tighter tolerance (±1% vs ±5%), lower noise and better temperature stability. They work as a drop-in replacement anywhere a carbon-film resistor is used.

Can I use a 1/4W resistor with Arduino or ESP32?
Yes. In typical 3.3V and 5V microcontroller circuits the power dissipated is far below 0.25W.

Do you sell other resistor values?
Yes — we stock 220Ω, 330Ω, 1kΩ and 10kΩ packs. Contact us for bulk quantities or other values.
