FOJAN Component Intelligence

Start with the full electrical and mechanical requirements: resistance value, tolerance, TCR, package size, power rating, maximum working voltage, pulse and overload behavior, operating temperature, and environmental requirements. For automotive designs, also verify AEC-Q200 or customer-specific qualification evidence.

PartGenie provides a searchable manufacturer part catalog when source catalog data is available; this FOJAN hub is the intelligence and navigation layer that summarizes product families, sourcing risks, and decision paths so engineers can move through the catalog more efficiently.

They may serve the same circuit function in some designs, but they should be treated as functional alternatives until the datasheet confirms resistance value, tolerance, package, power rating, sulfur-resistance specification, and application qualification.

Industrial-control and power designs often require thick-film chip resistors, alloy or ultra-low-ohm current-sense resistors, and anti-sulfur or automotive-grade options where harsh environments, high current, or reliability targets apply.
