Description
Production is strictly controlled and follow an extensive set of instructions established in production procedure for reproducibility. A special homogeneous film of metal glaze is sintered on high-grade ceramic rods (85%~96% AL2O3) and conditioned to achieve the desired stability and reliability.
The resistor elements are covered by a protective silicon coating designed for electrical, mechanical, and climatic protection. The leads are covered with a final pure tin plating for keeping perfect solderability and wonderful outlooking.
Color code rings designate the resistance value and tolerance in accordance with IEC60062 but the yellow and white color rings are used to replace gold and silver rings for better high voltage performance.
Digital marking is available upon request
Applications
High resistance, high stability, high reliability at high voltage circumstances
