Product Description
Product Overview
The Yuanhui Electronic Technology (Jiangsu) Co., Ltd. 2512 Alloy Resistance series offers high-performance metal alloy resistors designed for demanding applications. These resistors comply with RoHS requirements and undergo AEC-Q200 vehicle-specific testing. They feature parasitic inductance less than or equal to 5nH, making them suitable for precise circuit designs. Available in LE (large electrode) and SE (small electrode) types, these resistors provide a wide range of resistance values, power ratings, and accuracy tolerances.
