The 15 Ohm 1/4W 5% Copper Wire Through Hole Resistor
is a standard, general-purpose resistor commonly used in a variety of low-power
electronic applications. Below is a detailed description of its specifications
and typical uses:
Specifications:
- Resistance
Value: 15 ohms
This resistor has a resistance of 15 ohms, which is useful in applications
where a moderate current-limiting resistor or voltage drop is required. It
helps regulate the flow of current in 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 makes it suitable for low-power applications, such as
signal-level circuits, small power supplies, and other low-voltage
devices.
- Tolerance:
±5%
The resistor’s actual resistance value can vary by up to ±5% from the
nominal 15 ohms. This means the resistance could range from 14.25 ohms to
15.75 ohms. This level of tolerance is acceptable for general-purpose
applications where precision is not critical but reliability is important.
- Mounting
Type: Through hole
This resistor is designed with leads that pass through holes on a printed
circuit board (PCB), allowing for easy and secure soldering. The
through-hole mounting type provides strong mechanical support and is
commonly used in both prototyping and mass production.
- Material:
Copper Wire
The resistor is constructed with copper wire, which is chosen for its good
electrical conductivity and cost-effectiveness. Copper wire resistors are
widely used in low-power circuits where precision is not paramount.
Key Features:
- 15
Ohms Resistance: The 15-ohm resistance value is suitable for
current-limiting applications or in circuits where a moderate voltage drop
is required. It is commonly used in applications like controlling the
current in LEDs, regulating power supplies, or providing feedback in
amplifier circuits.
- 1/4W
Power Rating: The resistor has a 1/4W power rating, making it
appropriate for low-power applications. It is commonly used in circuits
that operate at low voltages and currents, such as in audio equipment,
sensor interfacing, or simple voltage regulation systems.
- 5%
Tolerance: With a tolerance of ±5%, the actual resistance may vary
slightly from the nominal value of 15 ohms, but the variation is typically
within acceptable limits for general-purpose applications. This level of
tolerance is commonly used in non-precision circuits.
- Copper
Wire Construction: Copper is a cost-effective material with excellent
electrical conductivity. While it may not be as thermally stable as
materials like metal oxide, copper wire is ideal for low-power
applications where cost and efficiency are the primary concerns.
Typical Applications:
- Current
Limiting: The 15-ohm value is often used in circuits where current
limiting is necessary to protect components from excessive current. It is
commonly used in LED circuits, motor drivers, and other power supply
systems where current needs to be controlled.
- Voltage
Division: This resistor can be used in a voltage divider network, in
combination with other resistors, to create a specific voltage drop. This
is useful in signal processing, sensor interfacing, and analog circuits
that require a reduced voltage.
