Unlike small carbon film or metal film resistors used in low-power signal circuits, this component is specifically designed to safely dissipate significant heat while providing precise, stable resistance in higher-power circuits — commonly used wherever excess current or voltage needs to be dropped, limited, or dissipated as heat in a controlled way.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eCore Electrical Ratings:\u003c\/h2\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eParameter\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eRating\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance Value\u003c\/td\u003e\n\u003ctd\u003e160Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTolerance\u003c\/td\u003e\n\u003ctd\u003e±5% (J-code)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Rating\u003c\/td\u003e\n\u003ctd\u003e50W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Continuous Current (calculated, @ rated power)\u003c\/td\u003e\n\u003ctd\u003e~0.56A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing Material\u003c\/td\u003e\n\u003ctd\u003eAluminum (anodized, gold finish)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eTwo mounting tabs with screw holes (for heatsink\/chassis mounting)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Style\u003c\/td\u003e\n\u003ctd\u003eFlying lead wires (axial)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTypical Operating Temp Range\u003c\/td\u003e\n\u003ctd\u003e-55°C to +155°C (standard for this resistor class)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2 dir=\"ltr\"\u003eImportant Usage Notes (for support\/troubleshooting reference):\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeatsinking significantly improves performance:\u003c\/strong\u003e While rated at 50W in free air, this resistor's aluminum housing is designed to be bolted to a metal chassis or heatsink via its mounting tabs — doing so allows it to dissipate heat far more effectively and reliably sustain closer to its full rated power.
