PTN15-C11SB20 PTN15-C11SB20 Trimmer Potentiometer

PTN15-C11SB20 is a high-quality trimmer potentiometer manufactured by Same Sky, a reputable name in passive components. This specific model falls under the category of trimmer potentiometers, which are variable resistors designed for fine-tuning and calibration in electronic circuits. Unlike standard potentiometers used for frequent user adjustments, trimmers are typically set once or a few times during manufacturing or servicing and are not intended for end-user manipulation. The PTN15-C11SB20, with its 1MΩ resistance and 0.15W power rating, is ideal for applications requiring precise resistance adjustment in a compact footprint, ensuring stable and reliable performance over its operational lifespan.

Key Specifications

The PTN15-C11SB20 boasts several critical specifications that define its functionality and suitability for various applications. The Resistance (kΩ) of 1000 kΩ, or 1 MΩ, indicates the maximum resistance value achievable, making it suitable for circuits requiring high resistance adjustments. A Resistance Tolerance (%) of 20% signifies the permissible deviation from this nominal resistance, which is standard for many trimmer applications where exact precision isn’t paramount but a range is acceptable. The Power (W) rating of 0.15W specifies the maximum power the device can safely dissipate without damage, an essential consideration for circuit design to prevent overheating. Its Size (mm) of 15mm refers to the body dimension, highlighting its compact nature, which is crucial for space-constrained designs. The Operating Temp Range (°C) of -10 ~ 70°C defines the environmental conditions under which the potentiometer can operate reliably, accommodating a wide range of typical indoor and some outdoor industrial environments. The Rotation (°) of 265° indicates the mechanical travel of the rotor from one end to the other, providing a good range for fine adjustments. The Taper is Linear, meaning the resistance changes proportionally with the angle of rotation, which is common for trimming applications. The Mounting Type is Through Hole, ensuring a robust mechanical and electrical connection to the PCB, enhancing durability and reliability. Finally, the Termination using Straight PC Pins simplifies soldering and integration into printed circuit boards.

Features and Benefits

• Precise Adjustment: The 265° rotation and linear taper allow for accurate and stable resistance tuning, crucial for calibration tasks.
• Compact Design: With a 15mm body size, this trimmer potentiometer is suitable for space-constrained electronic assemblies.
• Robust Construction: Designed for through-hole mounting with straight PC pins, ensuring a secure and reliable connection to the PCB.
• Wide Operating Temperature: Capable of functioning effectively across a -10°C to 70°C range, making it versatile for various environments.
• Screwdriver Adjustable Rotor: The screwdriver-actuated rotor ensures that adjustments are deliberate and not easily altered accidentally, maintaining set values.

Typical Applications

The PTN15-C11SB20 trimmer potentiometer finds its utility in a diverse array of electronic systems where precise, infrequent adjustments are required. One common application is in audio equipment, where it can be used for fine-tuning bias currents in amplifier stages or adjusting equalization settings during manufacturing to achieve optimal sound reproduction. In industrial control systems, these trimmers are invaluable for calibrating sensor outputs, setting threshold levels for alarms, or adjusting timing circuits to ensure precise operation of machinery. They are also frequently employed in power supply units for setting output voltage or current limits with high accuracy, compensating for component tolerances and ensuring stable power delivery. Furthermore, in test and measurement instruments, the PTN15-C11SB20 can be used for zeroing out offsets, calibrating gain stages, or fine-tuning reference voltages, contributing to the accuracy and reliability of the measurements. Its compact size also makes it suitable for integration into portable electronic devices where internal calibration is necessary for optimal performance and battery life management.

In summary, the PTN15-C11SB20 from Same Sky is a reliable and versatile trimmer potentiometer, offering precise resistance adjustment in a compact, through-hole package. Its robust design and broad operating temperature range make it suitable for a wide variety of professional and industrial applications.
