Key Features
- 100 kΩ resistance with 10% tolerance in a compact 3/8-inch (9.5 mm) square through-hole package for easy PCB mounting
- Single-turn cermet element provides smooth, repeatable resistance adjustment for precise analog calibration
- Through-hole leads simplify manual soldering and rework compared to surface-mount trimmers in low-volume or prototyping applications
Applications
The 67WR100KLF is used in analog circuit trimming applications such as op-amp offset nulling, voltage divider adjustment, and reference voltage fine-tuning in industrial instrumentation, audio equipment, and power supply circuits. Its 100 kΩ range and through-hole format make it a standard choice for board-level calibration where a screwdriver-adjustable resistor is needed during production test or field service.

Frequently Asked Questions
What resistance value and tolerance does the 67WR100KLF offer for precision trimming applications?
The 67WR100KLF provides a 100 kΩ resistance with a 10% tolerance, giving a trimming range from near 0 Ω to 100 kΩ across the adjustment arc. This wide range suits applications such as gain setting, offset nulling in op-amp stages, and reference voltage calibration where fine analog adjustment is required.
For a compact through-hole PCB design, how much board area does the 67WR100KLF occupy?
The 67WR100KLF uses a 3/8-inch (approximately 9.5 mm) square footprint, making it one of the more compact through-hole trimmer sizes available. This small outline allows it to fit in densely populated calibration circuits without displacing nearby components, supporting efficient use of PCB real estate in instrumentation boards.
In which analog calibration scenarios is a 100 kΩ through-hole trimmer preferred over a lower-value alternative?
A 100 kΩ trimmer like the 67WR100KLF is preferred when the circuit impedance is high, such as in CMOS op-amp input networks, audio tone controls, or high-impedance sensor bias networks where lower resistances would load the signal path. The 10% initial tolerance still provides sufficient adjustment range around the nominal operating point for most production trimming procedures.
