Recharging the Future: DKT-DZ Super Capacitors Lead the Way in Compact Imaging Systems

                Kingtronics International Company — Inspired by Innovation

  In a world where electronics are getting smarter and smaller, backup power solutions must evolve to meet higher expectations. For imaging devices that can’t afford a second of downtime, Kingtronics DKT-DZ Super Capacitors offer the perfect blend of speed, reliability, and compact design—without compromise.

Why Imaging Devices Need Smarter Backup

From high-resolution digital cameras and dashcams to security surveillance modules, modern imaging systems handle larger data loads, faster processing, and continuous operation. Traditional lithium batteries, while familiar, struggle with:

• Slow recharge cycles

• Limited lifespans

• Sensitivity to temperature shifts

• Space-consuming formats

These challenges can lead to missed frames, file corruption, or system reboots—problems you can't afford in professional or consumer imaging products.

DKT-DZ: Designed for Speed and Space-Saving

The DKT-DZ series is built for modern electronic design. Whether you’re working with modular PCBs or ultra-compact embedded systems, DKT-DZ offers a high-performance drop-in replacement for conventional battery-based backups. Key benefits include:

• ✅ Fast Charging & Discharging – Ideal for real-time data storage during power interruptions

• ✅ Low ESR (Equivalent Series Resistance) – Ensures minimal energy loss and better efficiency

• ✅ Over 500,000 Charge Cycles – Far outlasting the lifespan of traditional batteries

• ✅ Flexible Mounting Options – Available in radial, snap-in, and screw types

• ✅ Compact Dimensions – Perfect for space-constrained applications like wearable cams or slim enclosures

Built to Withstand Real-World Demands

Imaging systems must function flawlessly in dynamic environments—heat, cold, vibration, voltage fluctuations. The DKT-DZ capacitor is engineered for resilience, maintaining performance across temperature extremes and power spikes. For both consumer and industrial-grade applications, it ensures seamless operation during:

• Short-term outages

• Sudden voltage drops

• File-saving processes

• Real-time clock continuity

The Result? No Lost Images. No Reboots. No Compromise.

DKT-DZ super capacitors are already being adopted by manufacturers building the next generation of compact imaging electronics. Their footprint is small—but their impact on system performance is massive.

Kt Kingtronics Sharing More Information about Super capacitor with You

 Super capacitor is an electrochemical capacitor with the ability to store more energy than conventional capacitors. Super capacitors can charge and provide energy faster than batteries. The increasing application of instantaneous standby power supply promotes the demand for super capacitor.

The remarkable advantage of super capacitor is that it can cycle thousands of times before aging, while the battery can only cycle hundreds of times.
The latest development of super capacitor has introduced lithium-ion hybrid capacitors which can be charged to high voltage (up to 4V), which has less self-discharge and high energy density. The disadvantage of these super capacitors is that they cannot discharge to less than 2.2V, otherwise they will be damaged.

The composition of super capacitors makes their self-discharge rate significantly higher than that of battery. The higher the working temperature of super capacitor, the higher the charging voltage, the faster the aging; The capacitance of super capacitor will decrease and the equivalent series resistance (ESR) will increase. This means that the super capacitor can provide less energy for the application. ESR of capacitor increases power loss of the system.

The temperature is only 10% higher, the life of the super capacitor can be reduced by half. In addition, it is usually used to charge the super capacitor to a voltage below the nominal voltage to increase its life.

Since the maximum voltage of the super capacitor charging is between 2.7V and 3V, it is necessary to connect several super capacitors in series for most applications. Therefore, the super capacitor must be balanced; Otherwise, one unit may charge more than another, leading to the aging of unequal capacitors, reducing the capacity of capacitor banks to provide the energy required for application.

The methods used to balance the super capacitor include: passive balance of resistor string, switch resistor, zener diode and active balance. The first three methods can cause power loss in resistors, and the fourth is the most effective but also the most expensive.

When super capacitors are used for standby power applications, their capacitors and ESRs must be monitored to ensure that the minimum energy required for the application can be provided.

Super Capacitor applications: RAM; Detonator; car recorder; smart meter; Vacuum switch; digital camera; motor drive; clock circuit; UPS; toy; program-controlled switch; etc.

Kt Kingtronics Tell You Automotive / Industrial Demand for Automotive Capacitors Has Increased

Demand for automotive chips has unexpectedly increased recently, attracting the attention of analysts and investors. 

The survey shows that demand from the automotive and industrial industries is expected to recover from the fourth quarter to 2021.

The report from Barron`s indicated that the rebound in automobile market conditions is much better than expected, mainly due to the return of Chinese automobile production to the level before the epidemic, the 100% capacity utilization rate of US automobiles and trucks, and the low dealer inventory. 

There are also signs of improvement in the trend of the business cycle industry. China, the United States and Europe's Purchasing Managers Index (PMI) for the July-September quarter all indicate that the business is beginning to expand.

Aluminum Electrolytic Capacitors

Various types of capacitors can be found throughout automotive subsystems of all types of cars, including internal combustion engine (ICE) types that now dominate the market.

For example, aluminum electrolytic capacitors are employed in convenience systems like air conditioning, window wipers and motors used for automatic windows, seats and other purposes. 

These devices also are employed in key safety and control systems like power steering, airbag controls and braking systems. 

Furthermore, aluminum electrolytic capacitors are used in engine control units (ECU) for battery controls, gas- and diesel-engine controls and electric motor drives for uses like fuel pumps and fans.

Supercapacitor Car Battery

Supercapacitors promise to play a much larger role in the EV market in the future. A major factor inhibiting the acceptance of some EVs has been their limited range.

Recent breakthroughs in supercapacitors could make them a viable and superior replacement for lithium-ion batteries, however. Conventional supercapacitors can charge up much more quickly than batteries.
