PTN10-E05HB20 PTN10-E05HB20 Trimmer Potentiometer

PTN10-E05HB20 is a high-quality trimmer potentiometer manufactured by Same Sky, a reputable name in electronic components. This single-turn, 10mm component is designed for precise resistance adjustments in various electronic circuits. As a passive component, it functions by providing a variable resistance, allowing engineers to fine-tune voltage levels, current, or signal attenuation within a system. Its compact design and reliable performance make it a popular choice for applications requiring stable and accurate calibration.

Key Specifications

The Rotor of this trimmer potentiometer is Hexagonal, a design choice that often facilitates easier adjustment using standard tools, enhancing user convenience during calibration. The Taper is Linear, meaning the resistance changes proportionally with the rotation of the rotor. This is crucial for applications where a predictable and consistent response to adjustment is required. The absence of a Detent indicates a smooth, continuous rotation without discrete click stops, offering finer resolution for adjustments. Belonging to the PTN10 Series, this component is part of a family known for its compact size and reliability. The specification of No Bushing implies a direct mounting approach, often simplifying the mechanical integration into a PCB. With a Power (W) rating of 0.15 Watts, it is suitable for low-power applications, ensuring efficient operation without excessive heat generation. The compact Size (mm) of 10mm makes it ideal for space-constrained designs. The Orientation is Horizontal, which dictates its physical placement on a PCB, often preferred for low-profile designs. The Shaft Style is Shaftless, meaning adjustments are typically made directly on the rotor, further contributing to its compact form factor. Termination via Straight PC Pins ensures robust and straightforward through-hole mounting. The Mounting Type is Through Hole, providing a strong mechanical connection to the PCB. A Rotation (°) of 235 degrees offers a sufficient range for precise adjustments across its resistance value. As a Component Type, it is explicitly a Trimmer Potentiometer, designed for set-and-forget adjustments rather than frequent user interaction. It features Number of Turns as 1, indicating a single-turn device for quick adjustments. The nominal Resistance (kΩ) is 5 kOhms, a common value suitable for a wide array of circuit designs. A Resistance Tolerance (%) of 20% is standard for many trimmer potentiometers, indicating the permissible deviation from the nominal resistance. Finally, an Operating Temp Range (°C) of -10 to 70 degrees Celsius ensures reliable performance across typical industrial and commercial environmental conditions.
