What Stands Out
High Precision
Featuring a 1% tolerance, these resistors ensure accurate resistive values, essential for reliable electronic circuit performance.
Durable Material
Constructed from metal film, these resistors offer superior stability and longevity, making them suitable for use in demanding applications.
Cost-Effective Bulk
Packaged in convenient sets of 100, this bulk purchase provides exceptional value for hobbyists and professionals alike, reducing overall costs and downtime in projects.
Product Details
- 1% precision metal film resistor for LED projects - 100 1% tolerance metal film resistors for precision LED current limiting, voltage dividers, pull-up/pull-down networks, and general electronics applications with tight resistance accuracy
- Precision 1% tolerance metal film construction - 220Ω resistance with ±1% tolerance and low temperature coefficient for accurate, stable performance across operating range. Metal film element produces lower noise than carbon composition and maintains tight resistance accuracy over temperature swings and aging cycles.
- Axial through-hole package - Standard axial leads on a cylindrical body fit 2.54mm grid breadboards, perfboard, and standard PCB footprints. Leads accept hand soldering, screw terminals, or wire-wrap. Color-coded bands identify resistance value: red-red-brown-gold for 220Ω at 5% reference or brown band for 1% tolerance.
- Circuit-design context - 220Ω suits LED current limiting at 20mA on 5-6V rails with 1.8-2.2V LEDs, base-drive resistors for small-signal BJTs, pull-up/pull-down on logic lines, and RC timing networks paired with capacitors. Also serves as series protection on input pins and shunt loads in voltage divider configurations.
- Applications across electronics projects - 220Ω metal film resistors are a standard value for LED current limiting on 5V supplies, voltage divider networks setting reference levels, GPIO pull-up and pull-down on microcontroller inputs, breadboard prototyping, PCB assembly, electronics repair, and general hobby circuit construction.

Customer Questions & Answers
-
Question:
What is the significance of a 1% tolerance in resistors?
Answer: A 1% tolerance in resistors indicates that the actual resistance value can vary by 1% from its stated value. This is crucial for precise electronic applications where accurate resistance is essential for desired circuit functionality. For example, in audio circuits or precision measurement equipment, using resistors with tighter tolerances like 1% ensures better performance and reliability. -
Question:
What applications are suitable for 220 ohm - 1 Watt metal film resistors?
Answer: 220 ohm - 1 Watt metal film resistors are ideal for various applications including analog circuits, signal processing, and power supply circuits. Their stability and low noise characteristics make them suitable for audio equipment, precision measurement systems, and high-frequency applications. For instance, they are commonly used in audio amplifiers, where maintaining signal integrity is crucial. -
Question:
How does a metal film resistor differ from a carbon film resistor?
Answer: Metal film resistors offer better thermal stability, lower noise, and a higher precision compared to carbon film resistors. The metal film provides a consistent resistance value and better performance in high-frequency applications. Therefore, for projects requiring high accuracy and stability, such as in RF applications or precision sensors, metal film resistors are recommended. -
Question:
Can 220 ohm - 1 Watt resistors be used for LED applications?
Answer: Yes, 220 ohm - 1 Watt resistors are often used in LED circuits to limit the current flowing through the LED, preventing damage while ensuring optimal brightness. When calculating the resistor value needed for an LED, using Ohm's Law can help in determining the right resistance needed to achieve the desired current, making the 220 ohm resistor a good choice depending on the LED and power supply specifications. -
Question:
What does the '1 Watt' rating mean in resistor specifications?
Answer: '1 Watt' indicates the power rating of the resistor, meaning it can safely dissipate up to 1 Watt of power without overheating. This rating is important to prevent the resistor from burning out during operation. When designing circuits, ensure that the total power dissipated doesn't exceed this rating to maintain circuit integrity and performance. -
Question:
What are the temperature coefficient values for metal film resistors?
Answer: Metal film resistors typically have a temperature coefficient of about ±100 to ±200 ppm/°C, which means their resistance can change slightly with temperature. This value is much lower than that of carbon resistors, making them more stable in varying environmental conditions. For precision applications where temperature variations occur, it's beneficial to choose metal film resistors. -
Question:
Are there specific storage conditions for these resistors?
Answer: Yes, it is advisable to store 220 ohm - 1 Watt metal film resistors in a cool, dry environment. Avoid exposing them to high humidity or extreme temperatures, as these conditions can affect their performance and reliability. Proper storage ensures their longevity and maintains their resistance values, making them ready for use in your projects. -
Question:
What is the maximum voltage rating for 220 ohm - 1 Watt resistors?
Answer: The maximum voltage rating for a 220 ohm - 1 Watt resistor is typically around 200 to 250 volts, but it can vary by manufacturer. It’s crucial to consider this rating when designing circuits to prevent breakdown and failure, especially in high-voltage applications. Always refer to the datasheet for specific voltage ratings to ensure safe operation. -
Question:
Can these resistors be used in RF circuit designs?
Answer: Absolutely, metal film resistors like the 220 ohm - 1 Watt variant are commonly used in RF circuit designs due to their low noise characteristics and stability at high frequencies. They ensure minimal signal distortion and maintain the integrity of the RF signals, making them suitable for amplifiers and RF filter circuits. -
Question:
Where can I buy 220 ohm - 1 Watt Metal Film Resistors 1% Tolerance, Pack of 100?
Answer: You can purchase the 220 ohm - 1 Watt Metal Film Resistors 1% Tolerance, Pack of 100 from Ubuy in Cook Islands. Ubuy offers a wide selection of electronic components, making it a reliable source for your resistor needs.
