TO-220 Thin Film Power Resistor ( Non-Inductive Design)

Technical Features

• Base Plate Center Temperature : ≤ 25°C, rated power is 20W.

• Packaging : Standard TO-220 molded package, ceramic base with exposed terminals.

• M3 Screw Installation : Overcomes the mechanical weakness of axial resistors by directly applying screw pressure to the center of the resistor, enhancing thermal conductivity.

• UL94-V0 : Flame retardant material.

  Application Cases

  1. 1. Power Supply Regulation :
        • Scenario : In a switching power supply, this resistor can be used as a current-limiting component in the feedback loop to regulate output voltage.
        • Example : A 10Ω resistor with ±1% tolerance ensures precise current control, maintaining stable output under varying loads.
     2. Overcurrent Protection :
        • Scenario : In motor control circuits, the resistor can act as a shunt to monitor current flow and trigger protective mechanisms if the current exceeds safe limits.
        • Example : By monitoring the voltage drop across a 0.2Ω resistor, an overcurrent condition can be detected and mitigated using a comparator circuit.
     3. Heating Element Control :
        • Scenario : In precision heating applications, such as temperature-controlled ovens or industrial heaters, the resistor can be used to dissipate controlled amounts of power.
        • Example : A 100Ω resistor with high power rating (e.g., 20W) can be used to dissipate heat in a controlled manner, ensuring uniform temperature distribution.
     4. Signal Conditioning :
        • Scenario : In audio or signal processing circuits, the resistor can be part of a filter network to attenuate signals or adjust impedance levels.
        • Example : A 1kΩ resistor in series with a capacitor forms a low-pass filter, smoothing out high-frequency noise in audio signals.
