On March 9, 2025, a fire occurred at Panasonic's Device Solutions Division factory in Chitose City, Hokkaido, leading to a temporary suspension of production for several key electronic components. The affected products include Chip Multilayer Varistors (EZJ series), NTC Chip Thermistors (ERT series), and Varistors SMD Type HF Series (ERZHF series).
Impact on the Electronics Supply Chain
These components are integral to various applications across the electronics industry:
- Chip Multilayer Varistors (EZJ series): Provide surge protection in consumer electronics, industrial equipment, and automotive systems.
- NTC Chip Thermistors (ERT series): Used for temperature sensing and compensation in devices such as HVAC systems, medical instruments, and consumer electronics.
- Varistors SMD Type HF Series (ERZHF series): Offer over-voltage protection in power supplies, telecommunication equipment, and automotive electronics.
Given the widespread use of these components, the production halt is anticipated to disrupt supply chains globally. Many manufacturers rely on these specific parts, and sourcing alternatives may be challenging due to their specialized nature and the prevalence of single Approved Vendor Lists (AVLs).
