Product Description
Product Description
The Yuanhui Electronics 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 are tested to meet vehicle-specific AEC-Q200 standards. They feature parasitic inductance less than or equal to 5 nH, making them suitable for high-frequency circuits. Available in LE (large electrode) and SE (small electrode) types, these resistors provide robust performance across a wide range of resistance values and power ratings.
