Descrizione

Through-Hole Resistors 47K ohm 5% 1/4W – Pack of 25: Essential Electronic Components

This product offers a convenient pack of 25 standard through-hole resistors, crucial for a vast array of electronic projects. These passive components are fundamental for controlling current flow and voltage levels within a circuit, making them indispensable for hobbyists, students, and professional engineers alike.

Key Features and Specifications

  • Resistance Value: Each resistor has a nominal resistance of 47 Kilo-ohms (47,000 ohms). This mid-range value is highly versatile and commonly used in circuits for applications such as pull-up/pull-down configurations, current limiting for LEDs (depending on voltage), and voltage dividers.
  • Tolerance: With a tolerance of 5%, these resistors are suitable for general-purpose applications where precise resistance values are not absolutely critical. This indicates that the actual resistance value will fall within ±5% of 47K ohms.
  • Power Rating: Rated at 1/4 Watt (0.25W), these resistors are designed for low-power circuits, which is typical for most hobby electronics, microcontrollers, and small signal applications. The power rating defines the maximum amount of power the resistor can safely dissipate without overheating and failing.
  • Mounting Type: As ‘Through-Hole’ resistors, they feature leads that are inserted through holes on a printed circuit board (PCB) and then soldered. This mounting method is robust, easy to work with for manual assembly, prototyping on breadboards, and perfboards, and generally more resistant to physical stress compared to surface-mount components.
  • Packaging: Supplied in a pack of 25 units, this quantity is ideal for small projects, educational kits, repairs, or for stocking up on common values without over-purchasing.

Applications and Uses

The 47K ohm 5% 1/4W resistor is a workhorse in electronics and can be found in:

  • Hobby Electronics: Perfect for Arduino, Raspberry Pi, and other microcontroller-based projects.
  • Prototyping: Essential for breadboard and perfboard circuit development.
  • Educational Kits: Widely used in electronics learning kits due to their ease of use and versatility.
  • Current Limiting: While 47K is high for many direct LED applications, it can be used for very low current signals or in combination with other resistors.
  • Voltage Dividers: Crucial for stepping down voltages or creating reference points in a circuit.
  • Pull-up/Pull-down Resistors: Commonly employed to define a default state for digital input pins, preventing ‘floating’ states.
  • Filter Circuits: Used in RC filters for signal conditioning.
  • Repair and Replacement: A common value for repairing various electronic devices.

Why Choose Through-Hole Resistors?

Through-hole components remain popular due to their ease of handling, especially for beginners or those performing manual soldering. Their larger size compared to surface-mount devices (SMD) makes them simpler to identify, manipulate, and replace. They also offer excellent mechanical stability when soldered, making them suitable for applications where physical robustness is required.

Conclusion

This pack of 25 Through-Hole Resistors with a 47K ohm resistance, 5% tolerance, and 1/4W power rating provides excellent value and utility. It’s an indispensable component for any electronics enthusiast’s toolkit, enabling a wide range of circuit designs and ensuring reliable performance in low-power applications. Whether you’re building, prototyping, or learning, these resistors offer the consistency and adaptability needed for successful electronic projects.
