Anti-surge resistors reduce component count
Anti-surge chip resistors in Rohm’s SDR01 series deliver a rated power of 0.33 W in the 0402 (1005 metric) package. The devices save board space and lower component count by replacing larger-size resistors in automotive, industrial, and AI server applications that require increased mounting density.
With optimized resistive element and electrode designs, the SDR01 series achieves a high rated power in the 0402 size while maintaining the reliability expected of high anti-surge chip resistors. The devices maintain their 0.33-W rating at terminal temperatures up to 125°C, making them suitable for demanding thermal environments.
Qualified to AEC-Q200, the chip resistors operate over a temperature range of -55°C to +155°C. The SDR01MZPF has a resistance tolerance of ±1% and a resistance range of 1 Ω to 2.2 MΩ, with a TCR of ±100 ppm/°C from 10 Ω to 2.2 MΩ. The corresponding ratings for the SDR01MZPJ are ±5%, 1 Ω to 10 MΩ, and a TCR of ±200 ppm/°C from 10 Ω to 10 MΩ, respectively.
The SDR01 series is now in mass production.
