ROHM Launches High-Power Anti-Surge Resistors for Compact Electronics
Event summary
- ROHM introduced the SDR01 Series of high anti-surge chip resistors with 0.33W rated power in a 0402 size.
- The series is designed for automotive, industrial, consumer electronics, and AI server applications.
- Optimized resistive element and electrode designs enable high power handling in compact sizes.
- Products guarantee 0.33W up to a rated terminal temperature of 125°C, reducing thermal design burdens.
- Achieves a TCR of ±100ppm/°C for stable circuit operation in power supply and interface circuits.
The big picture
As electronic devices demand higher functionality and power in increasingly compact form factors, ROHM's SDR01 Series addresses critical needs for smaller, high-reliability chip resistors. This aligns with industry trends toward miniaturization and higher power handling in automotive, industrial, and consumer electronics, as well as AI server applications. The innovation reduces thermal design burdens and supports stable circuit operations, positioning ROHM as a key player in high-performance electronic components.
