Resistors offer power rating up to 750 mW
Other specifications include long-term stability to ±0.005% and low typical TCR of ±0.2 ppm/°C
Designed for avionics, military, and space applications, the wraparound surface-mount Bulk Metal Z Foil resistors are the industry’s first devices to provide high-power ratings up to 750 mW at 70°C. Specifications include long-term stability to ±0.005%, low typical TCR of ±0.2 ppm/°C, a power coefficient of resistance of ±5 ppm at rated power, and tight tolerance of ±0.02%.
The resistors feature a low thermal EMF of less than 0.1 μV/°C, voltage coefficient below 0.1 ppm/V, inductance lower than 0.08 μH, and response time faster than 1 ns. Noise generated by these resistors is less than –40 dB. A post-manufacturing screening option is provided in accordance with EEE-INST-002, DSCC, and EPPL, for devices in the 0805 through 2512 case sizes. (From less than $4 — samples available now, 6 to 8 weeks ARO.)
