A 4W precision resistor with the same 0.5Ω resistance and ±1% tolerance in a 2512 package, offering a significant power upgrade.
FRL2512FR500TS is a 1W, 0.5Ω, ±1% tolerance thick film chip resistor in a 2512 package. Finding a substitute requires matching the package and resistance while carefully evaluating tolerance and power rating for your application.
Tolerance and TCR differences can impact performance in precision applications.
The 2512 package is standard, and compatible alternatives are available.
VMS-R500-1.0-U is a strong pin-compatible upgrade. For a lower-cost option, FRM252WJR500TK is available but has a wider tolerance that must be verified.
Upgrade to a higher power, precision resistor like VMS-R500-1.0-U for improved reliability and performance.
The primary risk is accepting a substitute with a wider tolerance (e.g., ±5% vs ±1%), which can compromise circuit accuracy.
