Frequency Control & Battery Solutions
EI Sales provides frequency control and battery solutions for OEMs requiring high-reliability performance. We guide engineering teams using technical insights and trusted technologies across timing and power applications, starting at prototype and scaling through full production.
Specialized Markets and Industries
EI Sales supports OEMs across regulated and performance-critical sectors where timing precision and power reliability are non-negotiable. Our frequency control and battery solutions are designed to meet application-specific standards across a wide range of industries.
Consumer Electronics (Selective)
For select lines, we support high-volume consumer products like wearables, IoT devices, and smart accessories. Our value lies in helping design teams scale quickly with the right off-the-shelf or semi-custom solutions.
Industrial Automation
Automation systems rely on precise synchronization and uninterrupted power. We help engineers specify the right frequency control and battery technologies for factory robotics, sensors, and embedded control systems.
Medical Devices
We work closely with medical OEMs with timing components and battery packs built to meet ISO 13485 requirements and long-term patient safety. Applications range from portable diagnostics to implantable and surgical tools.
Aerospace & Defense
We collaborate on aerospace and defense designs with crystal oscillators that maintain stability under vibration and battery packs tested for high-temperature, high-impact environments. Our team helps engineers specify components that align with industry standards and long design cycles.
Heavy Vehicle & Off-Highway
For off-road, marine, and construction platforms, we supply robust components engineered to withstand thermal, shock, and moisture extremes. These solutions keep power stable and timing locked under load.
Frequency Control Product Capabilities
EI Sales offers a full range of frequency control components for timing-critical applications. Our solutions meet the requirements of both commercial and mission-grade designs, supporting engineers from initial specification through production ramp.
Quartz Crystals
Available in MHz and 32.768 kHz ranges, including automotive-qualified options. Stable across temperature and vibration, ideal for long-life embedded systems.
Oscillators (XO, TCXO, VCXO, OCXO)
Precision timing devices with low jitter and tight frequency tolerance. Applications include RF systems, instrumentation, and synchronized industrial controls.
MEMS Timing Devices
Compact and vibration-resistant, MEMS-based timing is a fit for mobile, wearable, and IoT products that demand miniaturization without sacrificing reliability.
Crystal Filters & Resonators
Used to refine signal performance and suppress interference in RF and communications systems. Available in standard and custom frequencies.
Custom Frequency Solutions
For designs with unique timing requirements, we provide support for crystal and oscillator customization, including load capacitance, drive level, and enclosure specs.
