Compact & Durable: FKT Capacitors for Demanding Applications

  Kingtronics International Company — Inspired by Innovation 

Choosing the right capacitor can make or break your circuit—especially when you're working with limited space or dealing with unstable power. Many engineers have shared stories of failed prototypes simply due to the wrong capacitor type. That’s why Kingtronics® FKT Series has become a favorite: it’s compact, reliable, and made to last under pressure.

What Makes FKT Capacitors Stand Out?

• Flame-retardant encapsulation (plastic + epoxy resin)
• Self-healing properties for higher durability
• RoHS-compliant and long operational life

Which Series Is Right for You?

• FKT-AA: Best for standard AC/DC circuits, household appliances, and audio systems. Range: 0.033μF–68μF, 100–630VDC.
• FKT-AB: Compact oval axial design for tight PCB spaces. Same electrical performance in smaller form.
• FKT-AC: Ideal for high-frequency, high-voltage circuits like inverters and industrial power modules. Rated up to 1250VDC with ultra-low loss.

Common Questions We Get

“Can I just replace any capacitor with an FKT?” Not always. Be sure to match the capacitance, rated voltage, and form factor to your layout. If you're not sure, we’re happy to help you compare.

Compact Trimming Resistors for Accurate PCB Adjustment – RKT Series

      Kingtronics International Company — Inspired by Innovation 

When designing high-performance electronic circuits, engineers often face the challenge of achieving precision without compromising on space. That’s where Kingtronics® RKT Trimming Resistors come in — offering compact, durable, and flexible solutions for board-level calibration.

Small Footprint, Big Accuracy

The RKT series is engineered with space-constrained applications in mind. Whether it’s a consumer gadget, a sensor module, or an industrial PCB, these trimming resistors deliver:

• Compact size: Fits dense circuit layouts
• Stable resistance values: Ensures long-term accuracy
• Top and side adjustment options: Matches your assembly flow
• Various shapes: Round, square, sealed — for mechanical fit and protection

Each model in the RKT series supports resistance values from 100Ω to 2MΩ, enabling fine-tuning for both analog and digital systems.

Mechanical Versatility for Modern PCBs

From vertical boards to low-profile builds, the RKT line includes multiple mounting styles:

Model	Adjust Type	Form	Ideal For
RKT-WA	Top	Round	Compact vertical placement
RKT-WB	Side	Round	Slim horizontal applications
RKT-WC~WD	Top	Square	Tight layout or double-sided PCBs
RKT-WE	Side	Square	Easy reach during rework
RKT-WF~WG	Sealed	Square	Harsh or dusty environments

Their small mechanical footprint helps maintain clearance in sensitive areas — a major plus for compact product design.

Targeted Applications

While general trimmers aim for versatility, RKT excels in on-board fine-tuning where space, stability, and control are critical. Common use cases include:

• Sensor calibration modules
• Medical and lab electronics
• IoT device tuning
• Power supply feedback trimming
• Audio preamp balancing

Why Choose RKT Over Standard Trimmers?

• Lower profile: Saves valuable PCB real estate
• Sealed options: Ideal for rugged environments
• Stable adjustment: Reliable under varying loads and temperatures
• RoHS compliant: Environmentally safe and globally sourced
