In today’s demanding electronic design landscape, where reliability, consistency, and space efficiency are critical, choosing the right capacitor can significantly impact performance and longevity. The Kingtronics® FKT Series Film Capacitors are engineered for stable operation across a range of high-performance applications, including EMI suppression, power filtering, and industrial electronics.

1. Multiple Series, One Unified Standard

The FKT series features a full spectrum of film capacitors designed for diverse circuit environments:

  • FKT-MB – Box type: Consistent dimensions for compact PCB designs
  • FKT-AD / FKT-AC – Axial types: Easy to integrate in lighting, audio, and power circuits
  • FKT-MQ – Subminiature design: Optimized for high-density layouts
  • FKT-MP – Designed for automatic insertion: Lightweight and assembly-friendly

2. Excellent Electrical Performance

  • Capacitance Range: 0.001μF to 47μF
  • Voltage Ratings: Up to 1250VDC
  • Dissipation Factor: As low as ≤0.0015 @ 1kHz
  • Tolerance Options: ±5%, ±10%, ±20%
  • Dielectric Strength: Withstands up to 1.7×UR

3. Built to Last in Harsh Conditions

All models in the FKT series are encapsulated with epoxy resin for superior resistance to:

  • High temperature
  • Humidity and moisture
  • Solvents and environmental contaminants

These properties make the FKT series ideal for industrial automationpower supply systems, and HVAC applications.

4. Applications Across Industries

Whether you're developing switch mode power supplies (SMPS)LED lighting circuitsaudio systems, or inverter modules, the FKT film capacitors offer the reliability and flexibility your projects demand.

  • Filtering and snubbing in power supplies
  • EMI suppression circuits
  • DC-link energy storage
  • Audio signal filtering

Kingtronics FKT Series Film Capacitors – Full Range for EMI Suppression and Industrial Use

Kingtronics International Company — Inspired by Innovation

When it comes to high-demand electronic applications, not all potentiometers are created equal. Kingtronics' RKT series offers a variety of wirewound and adjustable potentiometers engineered specifically for heavy-duty, high-power environments. But what makes them ideal for industrial-grade use?

1. High Power Handling Across the Series

The RKT-WS and RKT-WT series can handle up to 5000W and beyond, using robust aluminum or ceramic enclosures for stable heat dissipation. Ideal applications include:

  • Power supply units
  • Motor control systems
  • Load testing environments

From compact 50W models to massive 3000W configurations, RKT offers scalable solutions for demanding environments.

2. Precise Adjustment for Fine Control

For applications that require precision tuning, RKT-WJ (conductive plastic) and RKT-WP (digital knob) models deliver smooth adjustment curves, low noise, and high linearity. Key features:

  • Electrical travel up to 345°
  • Over 50 million rotational lifespan (RKT-WJ)
  • 0–14 scale digital feedback (RKT-WP)

3. Flexible Mounting & Rugged Construction

RKT-WQ models include enclosed metal casings suitable for outdoor or vibration-prone environments, supporting up to 82KΩ and 2000V. The RKT-WH carbon film option is perfect for budget-conscious applications with reliable results.

All RKT potentiometers are:

  • Easy to mount
  • Available in multiple sizes
  • Engineered for shock, vibration, and heat resistance

4. Wide Range, Unified Standards

The RKT series covers a spectrum from low-ohmic precision control to high-resistance voltage division:

Model Type Power Rating Key Application
RKT-WS Wirewound (Aluminum) 50W–5000W Heat-sensitive systems
RKT-WT Wirewound (Ceramic) 20W–3000W Power adjustment, load control
RKT-WQ Enclosed Resistor 5W–500W Rugged environments
RKT-WJ Conductive Plastic 2W Precision control
RKT-WP Digital Knob Manual adjustment interfaces
RKT-WH Carbon Film 2W General-purpose adjustment

Summary: When Stability Meets Versatility

If your circuit design demands high power tolerance, precise adjustment, and long-term reliability, the Kingtronics RKT series delivers a flexible, modular solution for both industrial and commercial systems.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
