Description

The E1 Ohm (0.1E) 1W 5% Through Hole Resistor is a general-purpose resistor commonly used in electronic circuits that require low resistance and high power handling. It has a resistance value of 0.1 ohms, a power rating of 1 watt (1W), and a 5% tolerance. This resistor is designed for through-hole mounting, making it suitable for a wide range of applications, including power regulation, current sensing, and general circuit protection.

Key Specifications:

• Resistance: 0.1 ohms (or 0.1E)

  • This low resistance value is ideal for applications that require minimal voltage drop, such as current sensing or low-resistance power distribution.

• Power Rating: 1 watt (1W)

  • The resistor can safely dissipate up to 1 watt of electrical power, which makes it suitable for circuits where moderate power dissipation is required without overheating.

• Tolerance: ±5%

  • The actual resistance can vary by up to 5% from the nominal value. For example, the resistance can range from 0.095 ohms to 0.105 ohms.

• Mounting Type: Through-hole

  • The resistor is designed for insertion into holes on a printed circuit board (PCB), where the leads are soldered to the opposite side. This type of mounting ensures strong mechanical connections and is ideal for both prototyping and final circuit assemblies.

Applications:

• Current Sensing:
  The 0.1 ohm resistor is commonly used in current sensing applications, where the small voltage drop across the resistor is measured to calculate the current flowing through the circuit.

• Power Regulation:
  It is used in power supply circuits, voltage regulation, and current limiting applications, where its low resistance helps regulate power while minimizing power loss.

• Voltage Drop Minimization:
  This resistor is ideal for applications that require minimal voltage drop, such as battery-powered systems, power-efficient designs, or high-current circuits.

• General-Purpose Use:
  With its 1 watt power rating and 5% tolerance, this resistor is suitable for various general-purpose applications, including low-power devices, amplifiers, and protection circuits.

Physical Characteristics:

• Size:
  Typically, a 1 watt resistor has a size of about 1/4 inch (6.35 mm) in length and around 1/8 inch (3.18 mm) in diameter, depending on the design.

• Construction:
  The resistor has a cylindrical body with two metal leads extending from each end, which are inserted into the PCB and soldered in place to ensure a reliable electrical connection.

Summary:
The E1 Ohm (0.1E) 1W 5% Through Hole Resistor is a versatile, low-resistance resistor designed for applications such as current sensing, power regulation, and voltage drop minimization. Its 1-watt power rating and 5% tolerance make it suitable for moderate power applications, while the through-hole mounting ensures durability and ease of use in both prototypes and finished products. This resistor is ideal for use in circuits that require efficient current flow with minimal loss.
