The 33 Ohm 1/4W 5% Copper Wire Through Hole Resistor
is a commonly used resistor for a variety of low-power electronic applications.
Below is a detailed description of its specifications and typical uses:
Specifications:
- Resistance
Value: 33 ohms
This resistor provides a resistance of 33 ohms, which is ideal for
applications requiring moderate current limiting or voltage drop control.
It is commonly used in low-power circuits where a specific resistance is
necessary for current regulation or voltage division.
- Power
Rating: 1/4 watt (0.25W)
The resistor can safely dissipate up to 1/4 watt (0.25W) of power without
overheating, making it suitable for low-power applications. This power
rating is appropriate for circuits that operate at low voltage and current
levels, such as audio equipment, small power supplies, or control systems.
- Tolerance:
±5%
The resistor’s actual resistance can vary by up to ±5% from its nominal
value of 33 ohms. This means the resistance could range from 31.35 ohms to
34.65 ohms. This level of tolerance is typical for general-purpose
resistors used in non-precision circuits.
- Mounting
Type: Through hole
The resistor has leads that pass through holes on a printed circuit board
(PCB), making it easy to solder and securely mount in both prototyping and
mass production environments. Through-hole mounting ensures a strong
mechanical and electrical connection.
- Material:
Copper Wire
The resistor is made from copper wire, which is a good conductor of
electricity and offers a cost-effective solution for low-power
applications. Copper wire resistors are commonly used when high precision
is not required, but reliable and efficient performance is necessary.
Key Features:
- 33
Ohms Resistance: The 33-ohm value is often used for current limiting,
voltage regulation, or as part of a voltage divider network. It is ideal
for use in circuits that require a moderate level of resistance to
regulate current or reduce voltage.
- 1/4W
Power Rating: With a power rating of 1/4 watt, this resistor is
designed for low-power circuits. It is well-suited for applications that
don’t require large amounts of power dissipation, such as signal
processing, small power supplies, or low-voltage circuits.
- 5%
Tolerance: The ±5% tolerance indicates that the actual resistance can
vary by up to 5% from the nominal value. This is acceptable for
general-purpose applications where high precision is not required, but
stability and reliability are important.
- Copper
Wire Construction: Copper is used for its good conductivity and
cost-effectiveness. It provides reliable performance in low-power circuits
where cost is a consideration but high precision is not critical.
Typical Applications:
- Current
Limiting: The 33-ohm resistor can be used to limit the flow of current
in a circuit. It is often found in LED circuits, motor drivers, or other
circuits where protecting components from excessive current is important.
- Voltage
Division: This resistor can be used as part of a voltage divider
circuit, in combination with other resistors, to reduce the voltage to a
level suitable for specific components. It is commonly used in signal
conditioning, sensor interfacing, and power supply circuits.
