Golledge is the UK's leading supplier of frequency control products, specializing in providing high-quality oscillators, quartz crystals, VCXOs, and other frequency control components to a wide range of industries. Our extensive range of products and expertise in the field make us the go-to choice for companies looking for reliable and innovative frequency control solutions.

At Golledge, we understand that electronics used in harsh environments require specialized components that can withstand extreme temperatures, strong vibrations, and radiation exposure. That's why we offer a comprehensive collection of crystals and oscillators designed specifically for harsh and extreme environments. 

Some of the harsh environment our crystals and oscillators help electronics function in include: 

  • High reliability medical
  • Wildlife tracking
  • Harsh industrial applications
  • Down-hole drilling
  • Military & aerospace
  • High shock

Various packages sizes are available down to 1.5x0.9x0.35mm, offering frequencies from 10.0kHz up to 250MHz (model dependent).

Golledge can provide frequency components with specifications suitable for the toughest uses, such as down-hole applications.

High shock

Most models offer shock survival levels of 5,000g or 10,000g, but specialist models can offer up to 125,000g for crystals, or 30,000g and beyond for oscillators.

High temperature

Operating temperature ranges of -55°C to 210°C (and higher) are available.

Military high shock applications

Crystal models are available with full military testing to MIL-C-3098, and oscillator testing to MIL-PRF-55310 is usually available on request. Additional charges will apply for this service however please speak to our team today who will be happy to discuss your requirements and help to find you the best solution.
