Description

A 91K Ohm 1/8W 5% Through Hole Resistor is a passive electronic component used to limit or control the flow of electrical current in a circuit. This resistor has a resistance value of 91,000 ohms (91KΩ), which means it resists the flow of electrical current by 91,000 ohms. The 1/8 watt (1/8W) rating indicates the maximum power the resistor can dissipate without being damaged, which is 0.125 watts. The 5% tolerance specifies that the actual resistance value could vary by ±5% from the nominal value, meaning the resistance could range from 86.45KΩ to 95.55KΩ.

This particular resistor features a through-hole design, meaning it has metal leads that pass through holes in a circuit board and are soldered on the opposite side. This makes it suitable for manual assembly, prototyping, or applications where components are placed on a traditional PCB (printed circuit board).

Key Features:

• Resistance: 91KΩ (±5% tolerance)
• Power Rating: 1/8 watt (0.125W)
• Tolerance: ±5%
• Type: Through-hole
• Application: Commonly used in voltage dividers, signal processing, biasing circuits, and current limiting applications.
• Size: Standard dimensions for through-hole resistors, making it compatible with typical hole sizes on most PCBs.

The 5% tolerance allows for minor variations in the resistor’s resistance, which is often acceptable in general-purpose electronics, especially in low-precision applications like basic signal conditioning and power supply circuits. This resistor is also designed to be highly reliable, ensuring stable performance across a wide range of operating conditions.

Applications:

• Voltage Divider Networks: Helps to create specific voltage levels in a circuit.
• Signal Filtering: Used in combination with capacitors or inductors to filter out unwanted frequencies.
• Current Limiting: Limits the amount of current flowing through certain components to prevent damage.
• Biasing Circuits: Helps set operating points for active devices such as transistors.

This resistor is an essential component for engineers, hobbyists, and technicians looking for a reliable, cost-effective solution for their electronic projects.
