The resistor’s compact footprint of \u003cstrong\u003e71.1 mm x 12.7 mm\u003c\/strong\u003e and a profile height of \u003cstrong\u003e3.10 mm\u003c\/strong\u003e maximizes board area utilization while maintaining mechanical stability. Early integration into motor drives, inverters, and industrial automation systems is facilitated by its standard \u003cstrong\u003eProduct Type: 8JS Series Synchronous Motor\u003c\/strong\u003e compatibility and flange mounting provisions when required.\u003c\/p\u003e\n\n\u003cp\u003ePerformance characteristics focus on minimizing measurement error and maintaining signal integrity across a broad thermal range. The \u003cstrong\u003etemperature coefficient of ±150 ppm\/°C\u003c\/strong\u003e ensures negligible resistance drift from \u003cstrong\u003e-65°C to +170°C\u003c\/strong\u003e, supporting harsh industrial environments. Above \u003cstrong\u003e100°C\u003c\/strong\u003e, the component features a \u003cstrong\u003epower derating of 0.8 W\/°C\u003c\/strong\u003e, enabling designers to predict thermal behavior accurately. Its intrinsic \u003cstrong\u003einductance of 2.5 nH\u003c\/strong\u003e (typical) supports high-speed switching without introducing significant reactive impedance. Superior \u003cstrong\u003einsulation resistance of over 10 GΩ at 500 VDC\u003c\/strong\u003e preserves electrical isolation in precision circuits. The \u003cstrong\u003eflammability rating of UL 94 V-0\u003c\/strong\u003e guarantees compliance with safety standards and secures the resistor against flame propagation.\u003c\/p\u003e\n\n\u003cp\u003eReliability is further enhanced by self-cooling capabilities, ensuring passive heat dissipation under continuous operation. The \u003cstrong\u003eMounting Style: Flange mounting\u003c\/strong\u003e option complements standard surface-mount configurations for flexible system integration. Compatible with encoder-based feedback loops—leveraging \u003cstrong\u003eEncoder System: Resolver\u003c\/strong\u003e or angular position measurements down to \u003cstrong\u003e10 angular minutes\u003c\/strong\u003e—this resistor supports precise motor control schemes. The keyed shaft and flange provisions allow seamless coupling with existing motor assemblies, supporting nominal speeds up to \u003cstrong\u003e4500 RPM\u003c\/strong\u003e and accommodating a broad set of industrial automation applications.
