Non-combustible oxidized metal film fixed resistors 'RSF/RSMF'
RSF/RSMF
Towards the standardization of power supply and inverter design! The "RSF/RSMF series," chosen for its top-level flame retardancy of UL94V-0 and extensive processing options.
Body (Product Introduction) Are you struggling with wanting to "reduce the heat risk associated with high output circuits" or "finding the optimal mounting shape that fits your PCB layout"? In the design of power supplies and inverter circuits, ensuring safety during abnormal conditions and flexibility in implementation are significant challenges that can impact the overall speed of development. This product, which has received numerous inquiries from designers over the past six months, smartly addresses these issues and achieves standardization in design (common parts). 【This product features】 Overwhelming safety: It uses UL94V-0 grade flame-retardant paint for its exterior, demonstrating high safety that does not ignite even during accidental overload tests. Excellent mounting adaptability: It supports a wide range of axial and radial taping, as well as various forming processes, making it ideal for space-saving on PCBs and automatic mounting. As a highly reliable power resistor, it contributes to the optimization of procurement and design, ensuring the safety performance of your products in one go.
