Features 1、EASY TO ACCESS: The single page of the product has 6 kinds of capacity values, 50 capacitors of each capacity value are divided into two pieces, each of 25, placed separately for easy access, non interference, easy to identify. The page is a loose page and can be removed from a single page for flexible use in multiple scenarios 2、EASY TO USE: Hot gold text with leather shell, like a thick book, possess suitable size, easy to save, side marking capacitor symbol, easy to find and use when erected display. Packaged into a book, built in coded symbols. Deep understanding of the use of scenarios and needs, the use of leather shell with metal buckle rack, as well as gum packaging, long term use does not fade, clear identification parameters, long lasting use and storage 3、ACCURATE AND POWERFUL: Capacitor sample book adopt industrial production, mechanical position and cutting, accurate length Specifications, and unified standards. The high performance material can give the tool powerful function. The careful carving can bring different experience to the engineer 4、COG FEATURES: Capacitor sample book kit possess low mass loss, high insulation resistant, good temperature characteristics. Especially suitable for oscillators, resonant circuits, coupling capacitors in high frequency circuits, and other circuits requiring low loss and stable capacitance, or for temperature compensation 5、CAPACITIVE PARAMETERS: The specific capacitance of X5R, X7R capacitors is large, the capacitance changes nonlinear with temperature, and the loss is large, which is often used in electronic equipment for bypass coupling or other circuits that require low loss and capacitance stability. Class II ceramic capacitors are divided into stable stage and usable stage. X5R and X7R belong to the stable level of the order ceramic Specification Item Type: Capacitor Sample Book Material: COG, X7R, X5R Capacity: 84 Values Suitable For: Engineer, student, proofing, maintenance, teaching, experiment Package List 1 x Capacitor Sample Book
