Vishay / Sfernice TS4Y Series Cermet Trimmers

Introduction

The Vishay / Sfernice TS4Y series is a compact surface-mount trimmer potentiometer family designed for reliable circuit adjustment in industrial electronic assemblies. With a 4.0 mm square footprint and single-turn cermet construction, these components provide a practical solution where small size, board-level tuning, and production-friendly mounting are important.

Part Description

TS4Y Series Cermet Trimmers are single-turn adjustable resistors intended for calibration and fine adjustment tasks on printed circuit boards. Their cermet resistive element supports stable adjustment behavior suitable for industrial electronics.

The series features a compact 4.0 mm square surface-mount package and is available in J-hook or gull-wing terminal configurations. These options support different PCB layout and mounting preferences. The devices are compatible with vacuum pick-and-place equipment, helping simplify automated assembly processes.

A fully sealed construction protects the trimmers during board washing operations, making them suitable for manufacturing environments that use post-assembly cleaning. The TS4Y series is rated for 0.25 W dissipation at 70°C.

Key characteristics include:

• 4.0 mm square surface-mount package
• Single-turn adjustment
• Cermet resistive element
• 0.25 W power rating at 70°C
• Fully sealed for board washing
• Vacuum pick-and-place compatible

Usage Ideas

1. Adjustable Sensor Interface
   Use a TS4Y trimmer to calibrate the gain or offset of an analog temperature, pressure, or light sensor signal before it reaches an ADC.

2. Programmable Bench Power Supply
   Install the trimmer in a feedback network to set a precise output voltage or current limit during final production calibration.

3. Threshold Alarm Module
   Add the trimmer to a comparator circuit so users can set the trigger point for an overtemperature, liquid-level, or battery-voltage alarm.

Conclusion

Vishay / Sfernice TS4Y Series Cermet Trimmers combine a compact 4.0 mm surface-mount format with industrial-focused features such as board-wash sealing, automated placement compatibility, and a 0.25 W power rating at 70°C. Their adjustable resistance function makes them well suited for calibration, tuning, and threshold-setting applications in space-conscious electronic designs.
