KOA: Pulse resistant high temperature resistor

14. October 2021

KOA now offers a resistor that combines pulse resistance with high-temperature characteristics. The series called HSG73P (sizes 0402 – 1206) can be used in ambient temperatures of up to 200⁰C. In relation to the ambient temperature, derating starts at 70⁰C; if the terminal part temperature is used as a basis, derating starts at 105 resp. […]

Pulse resistant SG73P series from KOA: Power Up

9. July 2021

The resistor manufacturer KOA has improved its pulse-resistant SG73P series. This means in particular the 0402 (1E) size, whose rated power is now 0.25 watt. This applies to a max. ambient temperature of 70⁰C or a terminal part temperature of 125⁰C. This component, called SG73P1EW, can be used, for example, to replace a standard thick-film […]

RN73R – KOA with improved Thin Film series

20. December 2019

The KOA industrial standard Thin Film series RN73 becomes RN73R. But not only the designation changes, some technical parameters also improve significantly. For example, derating in the context of Rated Ambient Temperature only starts at 85°C, compared to 70°C before. Furthermore the long-term stability during the Load Life Test (1000h) improves to ±0.1%, compared to […]
