ES Components is a Franchised Distributor of all SiTime products and is additionally appointed as the Logistics Provider for all SiTime military products. We offer 100% military up-screening for added reliability, and in-house programming for rapid delivery of products with custom frequencies and other configurations. We provide COTS, automotive, and military up-screened versions of SiTime devices.

Just A Phone Call Away


Do you need the higher confidence of Military up-screened SiTime MEMS oscillators?

ES Components offers up-screening of SiTime oscillators based on MIL-PRF-55310 requirements and MIL-STD-883 methods. Up-screening can be performed on 100% of the devices or a sample of each lot for characterization and lot acceptance. Standard flows are readily offered for up-screening at minimum added cost, however, customers may choose from an array of tests to create their own requirements in a Source Controlled Drawing (SCD). ES Components is ITAR registered and can receive ITAR drawings.

ES Components military up-screening can include 100% burn-in at maximum specified temperature with device in operation to screen out any infant mortalities. Devices can also be tested from hot to cold temperature extremes in 1⁰C increments, to prove full temperature range compliance. Environmental screenings, including centrifuge, thermal shock, temperature cycle and hermeticity fine/gross leak, are offered to screen devices based on MIL-PRF-55310 methods.

SiTime’s commercial products are very reliable and compared to quartz oscillators, offer many orders of magnitude better performance in harsh conditions such as shock, vibration, temperature change, power supply noise and electromagnetic interference (EMI).

Rugged Performance:

  • 30,000 g mechanical shock – 20X better

  • 70 g vibration – 3.5X better

  • 0.009 ppb/g g-sensitivity – 250X better

  • ±3.5 ppb/°C frequency slope (ΔF/ΔT), – 10X better

  • -55°C to +125°C operating temperature range products


  • Fully encapsulated MEMS resonator construction – vacuum sealed single crystal silicon, low mass, ultra clean, precision tolerances

  • Hermetic Elite Platform oscillators

  • Semiconductor manufacturing, supply chain 1 FIT (1 Billion Hours MTBF), 30X more reliable MIL-PRF-55310 Methods

Ease of Use:

  • No frequency jumps, activity dips

  • Place anywhere on PCB

  • Short lead times

  • Interposer boards for replacing existing quartz device board layouts

ES Components has established an inventory of the most popular field programmable devices that can be rapidly programmed to any frequency, voltage supply, frequency stability and other specifications within the family’s wide range options. Our inventory supports more than 50,000 permeations of part numbers; we can program and ship small quantities in 1-3 days.
