MVH series high temperature resistant aluminum electrolytic capacitors

Model Naming and Selection Guide

The MVH series adopts a clear model naming system, which facilitates users to accurately select the required products. Its format is MVH 10 VC 221 M H10 TP.

Series Name (MVH): Represents the MVH series.

Rated voltage: For example, 10 represents 10V.

Lead configuration (VC/VD):

VC: Vertical chip, 2 SMD terminals.

VD: Vertical chip, 4 SMD terminals (including 2 false pins for enhancing mechanical fixation), typically used for large-sized packages of L17 and above.

Capacitance value: For example, 221 represents 220 μ F (the first two digits are significant, and the third digit is the number of "0"). R22 represents 0.22 μ F, and 2R2 represents 2.2 μ F.

Capacitor tolerance (M): represents ± 20%.

Shell code: such as H10, K14, M22, corresponding to specific physical dimensions.

Packaging method (TP/TR):

TP: Standard tape packaging, suitable for sizes D55 to K16.

TR: Plastic tray packaging, suitable for large sizes such as L17 to M22, K14-K16 optional.

Summary and Design Application Suggestions

The MVH series high-temperature resistant aluminum electrolytic capacitors from United Chemi Con provide a high-performance solution for high reliability electronic system designers, thanks to their high temperature tolerance of 125 ° C, wide selection of CV values, rigorous lifespan testing, and solvent resistance characteristics. When designing circuits, the following points deserve special attention:

Reduced use at high temperatures: Although the MVH series can operate at 125 ° C, reducing voltage ripple or operating voltage appropriately can further extend the actual service life of capacitors where possible.

ESR and Ripple Current: In high-frequency applications such as output filtering of switching power supplies, ESR directly determines the heat generation and ripple voltage of capacitors. Be sure to select and design the heat according to the ESR value and rated ripple current provided in the data sheet.

Mechanical stability: For large-sized capacitors (L17 and above), it is recommended to prioritize VD packaging with 4 terminals to ensure sufficient mechanical reliability in environments with severe vibrations, such as automotive applications.

Cleaning process: For applications that require solvent cleaning, it is important to confirm whether the selected model (63V and above pressure resistant products) supports solvent protection and follow the cleaning guidelines recommended by UCC.
