The 22 Ohm 1/4W 5% Copper Wire Through Hole Resistor
is a versatile, general-purpose resistor commonly used in electronic circuits
for low-power applications. Below is a detailed description of its
specifications and typical uses:
Specifications:
- Resistance
Value: 22 ohms
This resistor has a resistance of 22 ohms, making it suitable for
applications where moderate current-limiting or voltage drop control is
required. It is commonly used to regulate the flow of current in various
low-power circuits.
- Power
Rating: 1/4 watt (0.25W)
The resistor can safely dissipate up to 1/4 watt (0.25W) of power without
overheating. This power rating is typical for low-power applications, such
as signal-level circuits, audio equipment, and small power supplies.
- Tolerance:
±5%
The resistor's actual resistance value can vary by up to ±5% from its
nominal value of 22 ohms. This means the resistance could range from 20.9
ohms to 23.1 ohms. The 5% tolerance is acceptable for general-purpose
applications where precision is not critical, but reliability is
essential.
- Mounting
Type: Through hole
The resistor is designed with leads that pass through holes on a printed
circuit board (PCB), making it easy to solder and securely mount onto the
board. Through-hole mounting is commonly used for both prototyping and
mass production, offering strong mechanical and electrical connections.
- Material:
Copper Wire
The resistor is made from copper wire, which is an excellent conductor of
electricity and a cost-effective material. Copper wire resistors are
widely used for low-power applications where high precision is not
required but reliability and efficiency are important.
Key Features:
- 22
Ohms Resistance: A resistance value of 22 ohms is suitable for use in
current-limiting circuits, voltage dividers, or as part of a feedback
network. This value is commonly used in circuits that require modest
current regulation, such as LED drivers, power supply filters, or
amplifiers.
- 1/4W
Power Rating: With a 1/4 watt power rating, this resistor is designed
for low-power applications where minimal power dissipation is required. It
is ideal for use in circuits that operate with low voltage and current,
such as audio systems, simple voltage regulators, and small control
circuits.
- 5%
Tolerance: The ±5% tolerance means that the actual resistance can vary
by up to 5% from the nominal value of 22 ohms. This level of tolerance is
typical for general-purpose resistors, and while it may not offer
precision accuracy, it is sufficient for most non-critical applications.
- Copper
Wire Construction: Copper is a commonly used material in resistors due
to its excellent conductivity and affordability. Copper wire resistors are
ideal for low-power circuits where cost-effectiveness is important and the
need for thermal stability or high precision is low.
Typical Applications:
- Current
Limiting: The 22-ohm resistor is commonly used in circuits where
limiting current is important. It is often used in LED circuits to prevent
overcurrent that could damage the LEDs, or in power supply circuits to
regulate current to sensitive components.
- Voltage
Division: In combination with other resistors, the 22-ohm resistor can
be part of a voltage divider network to reduce voltages to appropriate
levels for different stages of a circuit. This is useful in signal
processing, sensor interfacing, and voltage regulation.
