Littelfuse launches SM10 series varistor

Notably, it's the first surface-mounted MOV device to comply with the AEC-Q200 automotive standard, offering high-temperature endurance and ultra-high surge current handling in a compact form. A video showcasing the product is available for viewing.

Key features of the SM10 Series Varistor include:

• High operating temperature: withstands temperatures up to 125°C, ensuring reliability under harsh conditions
• AEC-Q200 compliance: meets stringent automotive electronics standards, making it suitable for EVs and charging stations
• Ultra-high surge capability: handles up to 40 pulses of 6KV/3KA surges, enhancing product reliability and lifespan
• Compact design: measuring 15.7 x 8.5 x 14mm, it saves PCB space and suits automated SMT PCB assembly
• Wide voltage rating: ranges from 130 to 625Vac, catering to a wide array of electronic applications

Johnny Chang, Director of product management at Littelfuse, stated: "The SM10 Series Varistors effectively protect electronic circuits against multiple transient voltage surges with ultra-high surge handling capability. They are AEC-Q200 compliant, enabling end-products to work in harsh ambient environments for longer lifetimes."

Amy Chu, Global Product Manager at Littelfuse, also remarked: "The vertical surface-mounted SM10 Series Varistors enable electronics designers to realise a 'SMT components only policy' for primary side circuit surge protection. Their compact size and ability to replace through-hole devices allow for fully automated and SMT PCB assembly processes."

The SM10 is well-suited for a range of challenging applications, including automotive electronics, building automation, appliances, consumer electronics, power storage systems, and high-end power supplies. Its high operating temperature, superior repetitive surge capability, and compact size make it a highly attractive option for industries in need of reliable high-surge varistors.
