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

Matters Needing Attention
- Chip resistor shall be stored in a room where temperature and humidity must be controlled. (temperature 5 to 35, humidity 45 to 75% RH). However, a humidity keep it low, as it is possible.
- Chip resistor shall be stored as direct sunshinedoesnt hit on it.
- Chip resistor shall be stored with no moisture, dust, a material that will make solder ability inferior, and a harmful gas (Hydrogen chloride, sulfurous acid gas, and Hydrogen sulfide).
- Storage life: 1 year.
