Diodes Incorporated FH SMD Miniature Quartz Crystal Ceramic (NKS2)
Diodes Inc. FH SMD Miniature Quartz Crystal Ceramic (NKS2) is a compact, high-performance quartz crystal designed to provide stable and accurate frequency generation for space-constrained electronic systems. Featuring a rugged AT-cut crystal resonator housed in a miniature 2.5mm × 2.0mm ceramic surface-mount package, the FH series offers reliable operation while supporting densely populated PCB layouts. The device is available across a frequency range of 12MHz to 66MHz and is supplied in tape-and-reel packaging for efficient automated assembly.
The Diodes Inc. FH series delivers excellent frequency stability and low phase-noise performance, with configurable load-capacitance options, tight frequency tolerances, and operating temperature ranges extending up to -40°C to +125°C (depending on the model). A robust construction and industry-standard environmental qualifications make the crystal well-suited for wireless and portable applications. These applications include BLUETOOTH®, wireless LAN, ZigBee®, ultra-wideband (UWB) devices, GPS receivers, USB peripherals, notebook computers, handheld PCs, PCMCIA cards, hard disk drives, and cellular communication equipment. The combination of miniature size, dependable frequency control, and broad application support makes the FH series an ideal timing solution for consumer, industrial, and embedded electronic systems.
