290G-12LF

290G-12LF clock oscillator IC 

290G-12LF is a surface-mount clock oscillator IC belonging to the 290G series precision timing component lineup, engineered with a 12pF load capacitance specification marked by the suffix "12LF", adopting lead-free four-pin ceramic metal seam-welded packaging that complies with RoHS, REACH and halogen-free industrial standards, featuring ultra-compact 1.0mm×1.0mm miniature outline with maximum seated height limited to 1.0mm for dense PCB layout integration, designed to deliver stable fundamental-mode clock signal output targeting consumer electronics, industrial control, IoT sensor modules and portable battery-powered devices, with wide operating temperature coverage from -40°C to +85°C, tight frequency tolerance of ±30ppm and excellent long-term frequency stability at ±0.0025% to eliminate timing drift in high-precision digital circuit systems, while supporting low driving power consumption of only 0.01µW to extend battery service life for handheld and wireless end products, and undergoing 100% full electrical testing before factory shipment to guarantee consistent batch performance and low failure rate in mass production.

290G-12LF Main Applications

290G-12LF serves as the core clock reference source for multi-category digital hardware systems, widely deployed in low-power MCU control boards, wireless Bluetooth/Wi-Fi communication modules, portable wearable smart devices including smart watches and fitness trackers, industrial miniature data acquisition sensors, handheld testing measuring instruments, automotive interior small electronic control units, household smart home sensor nodes, USB peripheral adapter circuit boards, medical portable monitoring equipment and low-speed serial communication interface modules such as I2C and SPI circuits, its low-power characteristic makes it especially suitable for battery-operated equipment requiring long standby time, while high frequency precision ensures stable data transmission synchronization to reduce signal loss and communication error rate in short-distance wireless and wired digital signal processing circuits, and the tiny packaging footprint maximizes usable PCB space for multi-functional integrated miniaturized product design.
