Single Layer, Microwave Capacitors (SLC)
Microwave Single Layer Capacitors for High-Frequency RF Designs
Overview:
Johanson Technology’s Microwave Single Layer Capacitors (SLCs) are designed for microwave and millimeter-wave RF designs requiring ultra-low loss, tight tolerances, and stable electrical performance at high frequencies. These capacitors support demanding applications in RF front-ends, microwave circuits, radar systems, and high-frequency communication infrastructure.
With ultra-low ESR and minimal parasitic inductance, SLCs enable reliable performance in RF bypass, DC blocking, impedance matching, and filter tuning circuits used in modern high-frequency systems.
Johanson Technology also provides custom SLC solutions. Design engineers are encouraged to bring their specific electrical and mechanical requirements—our engineering team works directly with customers to develop components optimized for performance, reliability, and application-specific constraints.
Key Features:
- 100% Manufactured in USA for shorter lead times
- High self-resonant frequency (SRF) for microwave circuits
- Ultra-low ESR and ESL for minimal signal loss
- Tight capacitance tolerances for precision tuning
- Non-magnetic and RoHS compliant
- Available in multiple case sizes and values
Typical Applications:
- RF tuning and filtering
- Impedance matching networks
- DC blocking and RF bypass in high-frequency designs
- Microwave and millimeter-wave circuits
- Radar and aerospace electronics
- Wireless infrastructure and medical RF systems
