Johanson Dielectrics’ Variable Pitch Capacitors are the ideal solution for demanding environments such as avionic systems, radar control electronics, and RF communication modules, where traditional lead spacing and component footprints fall short.

Designed for Non-Standard PCB Geometries

These capacitors are engineered to solve integration challenges caused by:

  • Irregular board layouts
  • Legacy PCB footprints
  • Tight mechanical envelopes

The customizable lead geometry allows a direct-fit solution without the need for PCB redesign—saving time, cost, and complexity.

Built for Harsh Conditions

Johanson’s Variable Pitch design maintains stable electrical performance across:

  • High vibration environments
  • Extreme temperatures from -55 °C to +125 °C

Johanson Dielectrics’ Variable Pitch Capacitors are engineered for high-voltage signal conditioning and filtering circuits in demanding energy environments—especially in downhole drilling systems and surface power electronics.

Built for Harsh Mechanical and Thermal Conditions

Energy systems often involve:

  • Custom or irregular enclosures
  • High mechanical stress
  • Elevated temperatures

Standard capacitor footprints often fall short. That’s where the Variable Pitch design comes in—with tailored mounting geometries that adapt to non-standard layouts and enclosures.

High-Temperature Ready

When built with X8R Class II dielectric materials, these capacitors maintain stable performance at operating temperatures up to 200 °C, making them ideal for:

  • Oil & gas drilling equipment
  • Renewable energy conversion systems
  • Power distribution units in extreme environments

Ideal for power regulation in MRI, CT, ultrasound, and other medical imaging systems, where stable voltage performance and low EMI noise are essential.

Engineered for High-Density, Shielded Layouts

In medical equipment, PCB space is often constrained by:

  • EMI shielding zones
  • Thermal management components
  • Compact mechanical enclosures

The Variable Pitch Capacitor provides a customizable solution, enabling:

  • Precise lead spacing for tight board layouts
  • Multi-capacitor integration in a single compact footprint
