Precision 1206 resistors handle 1W
The AEC compliant parts have “excellent electrical and environmental stability, showing minimal resistance shifts over most industry standard tests and are anti-sulphur per ASTM-B-809-95 with shifts less than 1%”, according to the company.
They are also AEC-Q200 compliant for automotive use.
Operation up to 200V (400V overload) and over -55 to +155°C (linear derating above 70°C to zero at 155°C).
Resistance values from 10Ω to 100kΩ are available, with 0.1%, 0.25%, 0.5% or 1% tolerance and ±10, 15
25 or 50ppm/°C drift.
