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
