Product Description
Product Overview
The Yuanhui Electronics Technology (Jiangsu) Co., Ltd. 2512 Alloy Resistance Specification details the Metal Alloy Resistance 2512 Series. These resistors comply with RoHS requirements and undergo vehicle-specific AEC-Q200 tests. They feature parasitic inductance less than or equal to 5 nH. Available in LE (large electrode) and SE (small electrode) types, with various power ratings, resistance tolerances, and a wide resistance range. The coding principle follows Manufacturer/Product, Size, Type, Power, Resistance, Accuracy, and Quantity.
