The 27 Ohm 1/4W 5% Copper Wire Through Hole Resistor
is a widely used resistor designed for general-purpose low-power electronic
applications. Below is a detailed description of its key specifications and
typical uses:
Specifications:
- Resistance
Value: 27 ohms
This resistor has a resistance of 27 ohms, making it ideal for moderate
current-limiting applications. It can be used where a specific voltage
drop is needed or where moderate current control is required in a
low-power circuit.
- Power
Rating: 1/4 watt (0.25W)
With a power rating of 1/4 watt, this resistor can safely dissipate up to
0.25W of power without overheating. This makes it suitable for low-power
applications, such as signal-level circuits, small voltage regulators, and
low-power control systems.
- Tolerance:
±5%
The resistor has a tolerance of ±5%, meaning the actual resistance value
may vary by 5% above or below the nominal value of 27 ohms. The resistor's
value could range from 25.65 ohms to 28.35 ohms, which is standard for
general-purpose resistors where precision is not critical.
- Mounting
Type: Through hole
This resistor is designed with leads that pass through holes on a printed
circuit board (PCB), making it easy to solder and securely mount.
Through-hole resistors offer a reliable mechanical and electrical
connection, commonly used in both prototyping and mass production.
- Material:
Copper Wire
The resistor is constructed from copper wire, which is a good conductor of
electricity and cost-effective for low-power applications. Copper wire
resistors are commonly used when high precision is not critical but
reliability and cost-efficiency are important.
Key Features:
- 27
Ohms Resistance: The 27-ohm resistance value is useful in applications
where moderate current regulation is needed. It is typically used in
voltage division, current-limiting circuits, or feedback networks in
low-power systems.
- 1/4W
Power Rating: With a 1/4W power rating, this resistor is suitable for
circuits where small amounts of power need to be dissipated. It is ideal
for low-voltage circuits, audio systems, signal processing, and other
applications that do not require high power dissipation.
- 5%
Tolerance: The ±5% tolerance allows for slight variations in the
resistor’s resistance, which is generally acceptable for non-precision
applications. This tolerance range is typical for general-purpose
resistors used in consumer electronics, hobbyist projects, and
non-critical applications.
- Copper
Wire Construction: Copper wire is chosen for its good conductivity and
low cost. While copper resistors may not be as thermally stable as metal
oxide resistors, they are ideal for low-power, cost-sensitive applications
where performance and cost are key considerations.
Typical Applications:
- Current
Limiting: The 27-ohm resistor is often used in circuits where current
needs to be limited to prevent damage to sensitive components. It is
commonly found in LED circuits, motor driver circuits, or power supply
circuits where current control is important.
- Voltage
Division: This resistor can be part of a voltage divider network, in
combination with other resistors, to reduce voltage to a specific level
for a particular part of a circuit. It is used in analog signal
processing, sensor interfacing, and various power supply circuits.
