Product Description
Product Overview
The Yuanhui Electronics Technology (Jiangsu) Co., Ltd. Metal Alloy Resistance 2512 Series is designed for high-performance applications. These resistors comply with RoHS requirements and undergo vehicle-specific AEC-Q200 tests. They feature parasitic inductance of less than or equal to 5nH, making them suitable for demanding electronic circuits. Available in LE (large electrode) and SE (small electrode) types, these resistors offer a range of power ratings, resistance values, and tolerances.
