The 4E7 Ohm (4.7E) 1/4W 5% Copper Wire Through Hole
Resistor is a versatile resistor commonly used in electronic circuits where
a resistance of 4.7 ohms is required. It is a general-purpose component,
designed for low-power applications. Below is a detailed description of its
specifications and typical uses:
Specifications:
- Resistance
Value: 4.7 ohms (4.7E)
This resistor provides a resistance of 4.7 ohms, suitable for
current-limiting applications or where a specific voltage drop is
required. It is commonly used in circuits for controlling the flow of
current or creating voltage dividers.
- Power
Rating: 1/4 watt (0.25W)
The resistor can safely dissipate up to 1/4 watt of power without
overheating or failure. This makes it suitable for low-power applications
where only small amounts of power need to be dissipated.
- Tolerance:
±5%
The resistor's actual resistance can vary by ±5% from the nominal value of
4.7 ohms. This means that the resistance may range between 4.465 ohms and
4.935 ohms, a typical tolerance for general-purpose resistors.
- Mounting
Type: Through hole
The resistor features leads that pass through holes on a printed circuit
board (PCB) for soldering. This through-hole mounting method ensures a
secure mechanical and electrical connection, making it ideal for both
prototyping and production-level applications.
- Material:
Copper Wire
The resistor is constructed using copper wire, which is favored for its
good electrical conductivity and cost-effectiveness. Copper wire resistors
are often used in low-power circuits where high precision or thermal
stability isn't as critical.
Key Features:
- 4.7
Ohms Resistance: This resistance value is commonly used in
applications such as current limiting in power supply circuits, voltage
drop control, or low-power signal conditioning. It can also be used in
high-current applications to reduce or regulate the flow of current.
- 1/4W
Power Rating: With a power rating of 1/4 watt, this resistor is
suitable for circuits where only small amounts of power are dissipated. It
is not suitable for high-power applications where significant energy
dissipation could occur.
- 5%
Tolerance: The resistor's tolerance of ±5% means the actual resistance
can vary within 5% of the nominal value. This is acceptable for
general-purpose applications where exact precision is not always
necessary.
- Copper
Wire Construction: Copper is a cost-effective material with excellent
conductivity. While it is not as thermally stable as other materials like
metal oxide, copper wire resistors are ideal for low-power applications
where cost and efficiency are important.
Typical Applications:
- Current
Limiting: The 4.7-ohm value is ideal for circuits where controlling
the flow of current is critical. It can be used in power supply circuits,
LED drivers, motor controllers, or any system requiring current regulation
to prevent damage to sensitive components.
- Power
Dissipation: Given its 1/4W power rating, this resistor is designed
for low-power circuits. It can be used in voltage regulation, simple
amplifiers, or as part of a power distribution system where minimal power
loss is acceptable.
