Resistors (Thin Film / Precision)

Precision resistors are widely used in RF circuits where accuracy and stability are key, particularly in signal paths and measurement applications.


Typical applications include:

  • Signal conditioning
  • Attenuation and termination
  • High precision circuits

Magnetics (Inductors, Ferrites & Filtering)

Magnetic components play an important role in RF and Microwave systems, particularly for filtering, suppression and signal control.


Typical applications include:

  • EMC and RF filtering
  • Inductance and impedance control
  • Noise suppression

Supporting Capabilities

Custom & Modified Manufacturing

RF and Microwave applications often require tightly controlled electrical characteristics or modified specifications. Charcroft supports custom and modified solutions, working closely with approved partners to deliver components tailored to your application.

Obsolescence & Hard-to-Source Components

RF components can present sourcing challenges, particularly for legacy or long-life systems. Charcroft supports obsolescence management and sourcing through a global network of approved suppliers, helping maintain continuity and reduce risk.
