About Capacitor Code Calculator

Decode electronic component markings with ease using Capacitor Code Calculator – the ultimate tool for engineers, students, makers, and hobbyists.

Whether you are working with ceramic disc, polyester film, or electrolytic capacitors, this app simplifies finding the capacitance, tolerance, and voltage ratings in seconds.

Key Features:
★ Bidirectional Calculations: Convert numerical marking codes (like 104 or 4R7) into value ratings, or enter values (pF, nF, µF) to generate the corresponding EIA standard code.
★ Dynamic 3D/2D Visualizer: Watch the capacitor render in real-time! The visualizer draws the capacitor body (Ceramic Disc, Mylar Film, or Cylindrical Electrolytic) and stamps the exact marking text directly on its surface.
★ Built-in Monospace Keypad: Type markings rapidly with a custom-engineered numeric and letter keypad featuring tactile haptic feedback.
★ Complete EIA Reference Guide: Access interactive, searchable lookup tables covering tolerance letters (J, K, M, etc.), voltage codes (2A, 1H, etc.), and ceramic dielectric classifications (Class 1 & 2 temp coefficients like NP0/C0G, X7R, and Y5V).
★ Calculation History: Save your decodings locally. Easily load them back into the calculator or swipe to delete.
★ Premium Dark & Light Themes: Work comfortably in any environment with a sleek glassmorphic dashboard styled for optimal contrast and readability.

No more guessing codes or digging through tables during a hardware build. Download Capacitor Code Calculator today!
