Frequently Asked Questions
Why choose an anti-sulfur resistor like RN73R2ATTD1001D25 for industrial panel designs?
Standard thick-film resistors can fail in environments with sulfur-containing gases because silver in the electrode migrates to form silver sulfide, causing open-circuit failures. The RN73R2ATTD1001D25 uses anti-sulfur construction to resist this degradation, making it reliable for industrial panels where the 1 kΩ, 0.5 mm profile SMT chip must retain precision over thousands of operating hours.
What package dimensions should PCB designers use when placing RN73R2ATTD1001D25 in a high-density layout?
The RN73R2ATTD1001D25 measures 2 mm × 1.25 mm with a 0.5 mm package height, corresponding to an 0805 SMT footprint. This compact profile allows designers to achieve high component density on multilayer boards, and the surface-mount format is fully compatible with standard reflow soldering at typical peak temperatures of 260°C.
How precise is RN73R2ATTD1001D25 for use in voltage divider and reference networks?
The RN73R2ATTD1001D25 is a precision chip resistor with a nominal 1 kΩ resistance. The RN73 series from KOA Speer is characterized by tight tolerances, making it suitable for precision voltage dividers, current-limiting networks, and feedback resistor pairs in operational amplifier circuits where 1% or better tolerance is required.
Is RN73R2ATTD1001D25 compliant with REACH and RoHS requirements for export to Europe?
Yes. The RN73R2ATTD1001D25 carries REACH Compliance Code: Compliant and meets RoHS requirements as indicated by its JESD-609 Code e3 designation. This makes it suitable for products sold in European Union markets, ensuring the 1 kΩ SMT resistor does not contain restricted substances above permitted thresholds.
