IQD Frequency Products is a recognized market leader in the frequency control and specialized timing sector. Known for delivering highly reliable and precise solutions, the company serves a broad spectrum of applications ranging from commercial-grade electronics to high-reliability industrial and automotive systems. Their commitment to quality is underscored by stringent manufacturing and testing standards, including ISO 9001 and automotive-grade certifications such as AEC-Q200. The comprehensive selection of IQD components focuses primarily on foundational timing devices, notably an extensive range of quartz crystals and standard clock oscillators. These core components provide the stable and accurate frequency generation required for diverse circuit designs, microcontrollers, and communication interfaces. Available in a variety of frequencies, tolerances, and packaging options, these crystals and oscillators form the reliable backbone of countless digital and RF systems. For more demanding environments that require enhanced precision, the portfolio also features specialized oscillator configurations. This includes advanced Temperature Compensated (TCXO) and Voltage Controlled (VC-TCXO) oscillators. These highly engineered timing solutions are designed to maintain exceptional frequency stability across fluctuating temperatures and varying operational conditions, making them ideal for telecommunications, networking infrastructure, and precision instrumentation.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
