Description

The 330K Ohm 1/4W 1% Through Hole Resistor is a high-precision, standard-size resistor designed for electronic applications requiring a specific resistance value, power rating, and tolerance. This resistor has a resistance of 330,000 ohms (330KΩ), making it suitable for circuits where high resistance is needed to limit current flow or set voltage levels.

Key Features:

• Resistance: 330KΩ, which makes it ideal for applications involving signal conditioning, voltage dividers, filtering, and other precision circuit designs.
• Power Rating: 1/4 watt (0.25W), indicating the maximum power the resistor can safely dissipate without overheating or causing damage to the component. This is suitable for most general-purpose circuits that operate at low to moderate power levels.
• Tolerance: 1% tolerance, meaning the actual resistance can vary by no more than ±1% from the nominal value. This ensures reliable and consistent performance for precision circuits where tight resistance values are necessary.
• Through-Hole Package: Designed for through-hole mounting, this resistor has lead wires that are intended to be inserted into a PCB (Printed Circuit Board) and soldered into place. This is a traditional and widely used mounting type for ensuring strong mechanical and electrical connections.

Applications:

• Signal Processing: It can be used in various analog signal processing circuits to set desired impedance or control current flow.
• Voltage Dividers: With its precise resistance value, it can be part of a voltage divider network to scale down voltages accurately.
• Amplifiers: It’s often used in amplifier circuits for biasing and setting feedback levels.
• Filtering Circuits: Useful in passive filter designs, where the resistor is part of the RC (Resistor-Capacitor) network to filter specific frequencies.

Mechanical and Electrical Characteristics:

• Body Type: Cylindrical, with the resistor leads extending from each end for easy mounting on a PCB.
• Construction: Made from a metal oxide or carbon film, providing stable resistance with low noise for high-performance applications.
• Size: Typically around 6.3 mm (L) x 2.3 mm (D), fitting most standard PCB designs without taking up excessive space.
• Operating Temperature: Can generally operate within a temperature range of -55°C to +155°C, making it suitable for a wide range of environments and industrial applications.

Benefits:

• High precision with a 1% tolerance for tight control in circuits.
• Durable and reliable with a low failure rate, making it ideal for mission-critical applications.
• Versatile for use in different electronic designs, from hobbyist projects to professional engineering.

This 330K Ohm 1/4W 1% Through Hole Resistor is an essential component for any electronic designer who needs to ensure stable, consistent resistance values in their circuits. It provides a combination of precision, reliability, and power-handling capacity for various applications, making it a go-to choice for both prototyping and production environments.
