Legacy Info High Q 0201 L Series

Johanson has instituted a new Global Part Numbering (GPN) system.

Only the part number is changing. The parts are produced with the exact same materials, manufacturing processes, manufacturing controls, dimensions, physical attributes and testing as the parts supplied with the legacy part numbers.

The GPNs will be phased in over the next several years and are planned to be completed by January 1, 2026.

We will continue to quote and accept orders with the current (legacy) part numbers throughout this period.

Beginning January 1, 2022, all samples will be provided with the GPN.

Updates associated with this change will occur periodically.

A database for the approximate 2 million crosses can be accessed at:https://www.johansontechnology.com/search/pn/

What makes the 0201 L-Series capacitor suitable for RF applications?

The 0201 L-Series capacitors are designed for high-frequency RF circuits requiring extremely low ESR, high self-resonant frequencies, and stable NP0 (C0G) temperature characteristics. These attributes help minimize losses and maintain circuit performance across frequency and temperature variations.

What dielectric is used in the 0201 L-Series?

The series utilizes NP0 (C0G) dielectric technology, providing excellent temperature stability, low loss, and predictable capacitance performance over a wide operating range.

How can engineers accelerate prototype development with the 0201 L-Series?

Designers can leverage available prototyping kits, S-parameter models, and product documentation to evaluate component performance quickly and reduce development cycles.

When should a designer select a High-Q capacitor instead of a standard MLCC?

High-Q capacitors are often preferred when minimizing RF losses, maximizing efficiency, maintaining precise tuning, or supporting high-frequency wireless performance is critical to the application.

Where are High-Q capacitors typically used on an RF circuit board?

Engineers commonly use High-Q capacitors in:

  • Impedance matching networks
  • RF filters
  • Antenna tuning circuits
  • Oscillators
  • Low-noise amplifiers (LNAs)
  • Power amplifiers (PAs)
  • Resonant circuits
