Laser trimming is a manufacturing process where a laser removes material from the resistive element to precisely adjust the resistance value to a target tolerance.
Precision Trimmed Resistors Component Intelligence
High-accuracy resistive components for critical signal paths.
What are Precision Trimmed Resistors components?
Precision trimmed resistors are used where absolute accuracy is non-negotiable. They utilize laser-trimming to achieve tolerances as tight as 0.005% and superior TCR, essential for precision voltage dividers, bridge circuits, and high-resolution data acquisition.
How to Choose Precision Trimmed Resistors Components
Select based on the error budget of your signal chain.
Tolerance Requirements
Define the absolute accuracy needed; laser-trimmed parts offer sub-0.01% precision.
TCR Stability
Temperature Coefficient of Resistance is critical; ensure it matches your operating temperature range.
Power Rating
Higher precision often limits power dissipation; verify self-heating does not drift the resistance.
Noise Floor
For low-level signal paths, prioritize low-noise metal foil or thin-film construction.
Long-term Drift
Check load-life stability specs to ensure accuracy holds over the product's intended lifespan.
