TTElectronics - Welwyn WINT0603LF0321R5B Precision Chip Resistor

The Welwyn WIN series are water-insoluble nitride thin film precision chip resistors. They feature a resistance range from 5 ohms to 1 megaohm, available in E24, E96, and E192 series. Manufactured using advanced metal film technology, these resistors offer high reliability and stability suitable for precision applications. They are available in T0603, T0805, and T1206 case sizes with power ratings of 0.1W, 0.25W, and 0.33W at 70°C respectively. The resistors come with tolerances of ±0.05%, ±0.1%, ±0.5%, and ±1%, and temperature coefficients of ±15ppm/°C, ±25ppm/°C, and ±50ppm/°C. They operate in ambient temperatures from -65°C to +150°C, feature anti-sulphur terminations, and demonstrate excellent moisture resistance with typical stability of ±100ppm. Rated for prolonged exposure in 85°C, 85% RH humidity conditions for 2000 hours, they provide high stability in humid and polluted environments and have superior moisture protection compared to passivated Nichrome chip resistors.
