Capacitor Prototyping Kits
High-Q, Low ESR Capacitor Kits for RF and Microwave Design
Johanson Technology RF capacitor prototyping kits provide high-Q, low ESR capacitor selections for RF and microwave circuit design. These capacitor kits are used for matching networks, RF tuning, output networks, RF bypass, DC block, couplers, and detector applications across multiple package sizes and capacitance ranges.
High-Q, Low ESR Performance
Designed for RF and microwave applications where low loss, high efficiency, and stable performance are required.
Broad Capacitance and Package Coverage
Includes multiple capacitance values across common RF package sizes, enabling fast component selection during design and tuning.
RF Prototyping and Tuning Efficiency
Organized capacitor kits allow engineers to quickly test, compare, and optimize circuit performance without sourcing individual components.
Designed for RF Applications
Supports PA matching, output networks, RF bypass, DC block, couplers, detectors, and high-frequency circuit development.
Improved RF Performance
High-Q capacitors help improve return loss, VSWR, and overall RF system performance.
Non-Magnetic Capacitor Kit Option
Non-Magnetic RF Capacitor Kits for MRI, NMR, and other sensitive environments
Johanson reserves the right to make limited value/tolerance substitutions when necessary.
