This product is a multilayer ceramic capacitor with extremely high volumetric efficiency, nonlinear capacitance change, and Y5U characteristic. It is used for blocking, coupling, decoupling, and interference suppression.
The EPCOS B37979N series provides leaded multilayer ceramic capacitors in several dielectric classes (C0G, X7R, Z5U/Y5U) with standard rated voltage of 50 VDC. The document lists detailed electrical parameters, dimensional drawings, and typical characteristics such as dissipation factor and insulation resistance.
Packaging options include cardboard tape, ammo packing, 360‑mm reel and bulk. Ordering codes are provided for a range of capacitance values from 10 nF up to 1 µF, with lead spacings of 2.5 mm or 5.0 mm. The brochure also outlines typical applications like blocking, coupling, decoupling and interference suppression.
