Aluminum Electrolytic Capacitors: Solid Polymers and Aluminum Electrolytics

Aluminum electrolytic and solid polymers, both have advantages and disadvantages when comparing to one another. Designers need to be aware of these differences when determining which capacitor type is best suited for use in their application.

The most notable difference between aluminum electrolytics and polymers is their electrolyte. Aluminum electrolytics have a liquid electrolyte while polymers have a solid electrolyte. These differences play a major role in the characteristics of each type of capacitor.

The solid polymer electrolyte gives the polymer capacitors advantageous characteristics over liquid aluminum electrolytic capacitors.

🔎The advantages are as follows:
🔘 Lower ESR at high frequency
🔘Lower D.F. / tan δ
🔘Higher ripple current ratings
🔘 Stability over temperature
🔘Wider operating frequency range
🔘Long life

Kt Kingtroncs-Work Together for Preparing the Upcoming 5G Era with Increasing Demand of MLCCs

It said most popular topic in 2018 is Artificial Intelligence (AI), then the promising keyword in 2019 must be 5G mobile communication technology.

As EPCI reported:

In many respects, however, 5G will be a two-edged sword in that customer demand for new 5G mobile phones in 2019/20 is going to put additional strain on capacity within the electronic components supply network as components manufacturers and their distributors struggle to keep up with demand.

Here’s why: smartphones are the largest application market for multilayer ceramic chip capacitors (MLCCs) and at a time when major MLCC manufacturers are trying to increase production capacity to alleviating the current shortage, the dawning of the 5G era will rapidly increase the amount of MLCC s used. The average MLCC usage of 4G + (LTE-advanced) smartphones is estimated to be in the range of 550 to around 900, and it is predicted that each device in the 5G era will boost this number to more than 1,000.

We can imagine it will be a new trend and challenge to the components manufacturers and distributors for the upcoming increasing demand.

In order to have well-prepared, Kingtronics could support MLCC with Radial & SMD type with competitive lead time.

Pls feel free to share if any possible demand, we’re willing to share your burden through tough time.

Let’s work together for the prospect 5G new era ! ^@^
