The 67WR2M series from BI Technologies Corporation is a line of through-hole trimmer resistors rated at 2M Ohms with a tolerance of ±10%. These components are designed for applications requiring precise resistance adjustments without soldering. If you're working on projects that need adjustable resistances, such as test equipment, audio circuits, or calibration setups, these trimmers are a go-to solution. They offer a simple way to fine-tune circuit performance by allowing manual adjustment of the resistance value.

One thing worth noting is their robustness; they are built for environments where mechanical durability is crucial. Engineers tend to reach for these when they need a reliable, easily adjustable resistor that can withstand repeated adjustments and harsh conditions. The through-hole design makes them easy to integrate into existing PCB layouts, though they do take up more space compared to surface-mount alternatives. Another practical use is in prototyping and testing, where quick and easy adjustments are necessary.
