Explore key design factors and discover reliable options for long-term performance.
When stability matters, plastic film capacitors remain one of the most trusted passive components for engineers. From power supplies and automation systems to lighting controls and industrial inverters, their low loss and consistent performance make them indispensable in modern circuit design.
But how do you choose the right one—especially when reliability and layout flexibility are critical?
In high-performance applications, energy loss can’t be ignored. A low dissipation factor (DF) prevents overheating and extends capacitor life.
✅ Kingtronics FKT-MM offers an ultra-low DF of 0.1%, helping maintain circuit stability even under prolonged operation.
Whether you're designing a compact power module or an industrial control board, capacitor form factors matter.
The FKT series offers multiple structures — Mini Box, Stacked, and Box Type — with various pitch and lead options to simplify PCB layout without compromise.
More than just capacitance and voltage, the internal construction and film quality determine how a capacitor performs over time.
The Kingtronics FKT-MS / MT / MM series is known for consistent thermal stability and endurance under switching stress, ensuring long-term reliability in demanding environments.
For projects that cross borders or industries, compliance matters.
The entire FKT series is RoHS-compliant, and widely used in industrial electronics, energy systems, and control modules.
Whether you're upgrading an industrial system or building from scratch, the Kingtronics FKT Series gives you the performance, flexibility, and reliability you need — without compromise.

Kingtronics International Company — Inspired by Innovation Power loss might only last a few milliseconds—but that’s all it takes to corrupt memory, crash modules, or reset real-time clocks (RTC). In critical applications like smart meters, embedded memory modules, or compact UPS control boards, even a short interruption can cause data errors, configuration loss, or system downtime. While traditional battery backups and large capacitors have long been used, they often come with trade-offs: bulky form factors, limited lifespans, or slow response times. That’s where Kingtronics DKT-DA Super Capacitor steps in. The DKT-DA series is designed to deliver rapid-response energy storage in a compact footprint, tailored for: With 5.5V rated voltage and up to 1.5F capacitance, this coin-type super capacitor supports flexible mounting orientations (C/V/H), making it ideal for modern, space-constrained designs. More than just backup power, it’s design assurance—helping prevent unexpected failures and ensuring long-term system integrity. The DKT-DA boasts up to 500,000 charge/discharge cycles, eliminating many of the reliability concerns that come with batteries. It’s maintenance-free, stable across operating temperatures, and ready for harsh environments. Whether you’re upgrading a smart grid solution or refining your embedded system architecture, reliable power backup isn’t a luxury—it’s a necessity. We’re here to help you optimize your systems and designs. Learn more from our product specs: Visit our website for more details: Contact us directly:Reliable Backup for RAM, RTC & Embedded Modules
