Overview

The Yageo MFR-25FBF52-20K is a through-hole, metal film fixed resistor from the MFR-25 series. It is designed for general-purpose and precision electronics where stable 20 kΩ resistance, good temperature stability, and low noise are required. As a typical 1/4 W (0.25 W) axial lead resistor, it is suitable for through-hole PCBs, supporting standard low-voltage analog and digital circuits. The metal film construction offers tighter tolerance and better long-term stability than carbon film types, making this part a solid choice for signal conditioning, bias networks, and feedback paths in a wide range of equipment.

Applications

• Precision biasing and gain-setting networks in analog amplifier and op-amp circuits
• Voltage divider networks in measurement, sensing, and control systems
• Signal filtering and timing networks in audio, instrumentation, and test equipment
• General-purpose pull-up, pull-down, and termination resistors in microcontroller and digital logic designs
• Power supply feedback and monitoring circuits in industrial and consumer electronics
• Educational, prototyping, and lab development boards using through-hole components

Alternatives & Replacement

Depending on stock levels, lead time, or specific design constraints, it may be necessary to consider alternative parts within the same resistor family. Yageo offers multiple resistance values in the MFR-25FBF52 series that share the same package, power rating, and general electrical characteristics, allowing easy substitution when a different resistance is acceptable in the circuit.

Recommended alternatives:

• Yageo MFR-25FBF52-1K24 – same series, 1.24 kΩ, full drop-in mechanical and package compatibility
• Yageo MFR-25FBF52-5K62 – same series, 5.62 kΩ, full drop-in mechanical and package compatibility
• Yageo MFR-25FBF52-8K45 – same series, 8.45 kΩ, full drop-in mechanical and package compatibility
• Yageo MFR-25FBF52-12K1 – same series, 12.1 kΩ, full drop-in mechanical and package compatibility
• Yageo MFR-25FBF52-221K – same series, 221 kΩ, full drop-in mechanical and package compatibility

Engineering note: even within the same resistor family, always verify that the replacement value, power rating, tolerance, temperature coefficient, voltage rating, and axial lead spacing match your design requirements. Ensure that substitutions will not affect bias points, timing constants, or safety margins in the target circuit.
