ABOUT US / HISTORY
Headquartered in Orange County, California with joint-venture partners located in Korea, China, and Taiwan Suntsu Frequency Control, Inc. was established in 2002 by professionals from the frequency control industry with 3 key principles in mind:
  1. Build a product line-up that covers the full spectrum crystal based frequency control devices thus giving customers a single source for all their frequency control needs.
  2. Encourage creativity and support industry innovation by designing and manufacturing custom components specific to our customers' applications.
  3. Foster long-term customer relationships by providing high quality products with on-time deliveries.

In 2003 we were certified to the American National Standard of ISO 9001:2000 by Det Norske Veritas and soon after were awarded key contracts from Fortune 100 customers and their respective contract manufacturers which helped to facilitate our growth.

Over the next 3 years our product line grew quickly. We went from being heavily concentrated in ultra-miniature crystals and TCXO's to offering a full assortment of low noise oscillators and VCXO's. In 2007 we further expanded our line to include an abundance of high stability/low noise OCXO's to fulfill requirements like base station, and military communication equipment applications where the highest frequency stability possible from crystals is needed.

In 2008 we turned our eye to Precision Time Modules and introduced 3 GPS disciplined OCXO's. One of which, broke industry ground being the first unit of its' kind to be board mountable.

Today, Suntsu is equipped to meet the needs of the most stringent frequency control requirements to the most basic. Our monthly capacity has grown tremendously in the last few years and as of 2009 we can support 33+ million components per month.

Our extensively trained sales staff is always available to assist you from the prototype stages of your product on through full-scale production. We pride ourselves on providing you with the most up-to-date information in the shortest amount of time. We recognize the importance of time to market for emerging technologies and have developed internal infrastructure to meet your demands.

In today's economy technology companies require nimble suppliers that support their engineering teams and their unique applications with quality products, competitive pricing and dependable deliveries. Suntsu is committed to being that supplier.
