1. These capacitors which adopt polypropylene film sa most suitable for oscillation circuits and filters requiring high performance and high stability in electronic equipment and are high precision capacitors with little aging. 2. The armor is a powder coated flame resisting epoxy resin.(UL 94 V-0) 3. Non-inductive structure in which leads are directly welded to an aluminum terminal. 4. Small tan ,good high-frequency performance. 5. High insulation resistance. 6. Temperature coefficient of capacitance is negative and almost constant. BOXES/2000.
