1、 Industrial control application scenarios and core values

Power Management and Filtering

In PLCs, servo drives, and motor controllers, surface mount aluminum electrolytic capacitors achieve

 efficient ripple suppression through low ESR characteristics (usually<50m Ω), which can reduce power

 ripple to less than 5% of the rated value. For example, in industrial frequency converters, their filtering

 capability can support switching frequencies up to 100kHz.

Energy storage and energy buffering

Used for robot joint drive systems and automation equipment, it can provide emergency power in the 

event of a 1-10ms short power outage, with a typical capacity range of 470 μ F-2200 μ F/63V. A case 

study of an industrial robotic arm shows that six 1000 μ F capacitor groups can support a 500W motor 

to run continuously for 0.5 seconds.

High frequency noise suppression

In industrial Ethernet communication modules and sensor circuits, surface mount aluminum electrolytic 

capacitors achieve high-frequency noise attenuation above 10MHz through low ESL design (<3nH), and 

are combined with ceramic capacitors to construct a composite filtering network.

Pulse circuit support

Suitable for pulse generation circuits in laser cutting machines and welding equipment, supporting μ s

 level fast charge and discharge cycles, with typical parameters including withstand voltage of 100V and

 capacity of 330 μ F ± 20%.

2、 Industrial control environment adaptation characteristics

Extreme temperature adaptability

The working temperature range of mainstream products has been extended to -55 ℃~125 ℃, and the

 FOLLON FVG series can have a lifespan of up to 5000 hours in an environment of 105 ℃. Through 

oxide film strengthening technology, high-temperature leakage current can be controlled below the 

rated value of 0.01CV.

Mechanical reliability improvement

Adopting enhanced resin packaging and passing 10-55Hz/1.5mm amplitude vibration testing

 (IEC60068-2-6 standard), it is suitable for strong vibration scenarios such as CNC machine tools.

Long-Life Technology 

The lifespan index of industrial control specific models generally reaches 8000-10000 hours (@ 105 ℃), 

and the annual capacity decay rate is controlled at<5% through a low volatility electrolyte formula.

3、 Key technical parameters for industrial control selection

Typical requirements and selection suggestions for parameter industrial control

Rated voltage 1.5 × peak voltage of the circuit 50V/63V/100V, three mainstream specifications

ESR ≤ 50m Ω @ 100kHz, preferred conductive polymer hybrid type 4

Ripple current needs to be calculated for heat loss Δ T ＜ 15 ℃, referring to IEC61000-4-17 standard

Temperature cycling -40 ℃~125 ℃ 500 times, choose glass sealed end structure

96 hour salt spray test requirement for anti sulfurization performance: gold-plated terminals

4、 Typical application cases

Industrial robot controller

Using a 35V/220 μ F capacitor bank, instantaneous current compensation of the servo driver is 

achieved with a response time of less than 10 μ s.

Smart grid relay protection device

100V/470 μ F capacitors are used for energy storage in fault recording circuits, meeting the 

IEC60255-24 standard.

CNC machine tool spindle drive

The 63V/1000 μ F low ESR capacitor (ESR<20m Ω) effectively suppresses IGBT switching spikes.

5、 Technical Challenges and Development Trends

High-frequency contradiction

The impedance of existing industrial capacitors significantly increases in the frequency range of>500kHz,

 and the applicable frequency is being extended to 2MHz through nano oxide film technology.

Intelligent monitoring integration

In 2025, new products will begin to integrate temperature/voltage sensors and support predictive 

maintenance (such as TDK's iC series).

Environmentally friendly material substitution

The new EU industrial control equipment regulations require the elimination of PFOS containing

 electrolytes by 2027. Currently, water-based electrolyte technology has achieved a lifespan of 85 ℃/2000h.

The field is developing towards "high-frequency+intelligent+environmentally friendly" direction, and 

it is expected that the market size of industrial control surface mount aluminum electrolytic capacitors 

will exceed 4.2 billion US dollars (CAGR 8.7%) by 2028.
