The HC-49USX is a low-profile, thru-hole quartz crystal designed for stable frequency reference in electronic circuits. It has a maximum height of 3.5 mm and is soldered with a peak temperature of 260°C for up to 10 seconds over two cycles. The part operates from -10°C to +70°C with a frequency stability of ±50 ppm over that range and a frequency tolerance of ±30 ppm at +25°C. It supports frequencies from 3.570 MHz to 70.000 MHz, with equivalent series resistance ranging from 30 Ω to 200 Ω depending on frequency and mode, using fundamental or 3rd overtone operation. Load capacitance is specified in the part number and defaults to 10 pF or 20 pF. The device is RoHS compliant, has a shunt capacitance of 7 pF, and a maximum drive level of 500 μW. Aging is ±5 ppm over the first year at +25°C.
Despite the rise in popularity of surface mount technology (SMT) in passive components, through hole packaging has remained an industry staple for eight decades for a reason. The simplicity and efficacy of this technology, along with its ability to be incorporated into a vast array of designs, make it an excellent choice for many different applications.
Crystals with through hole packing are ideal for larger components that will undergo a significant amount of mechanical stress, high voltage, and/or high power. This is because through hole soldering results in a stronger bond between the passive components and the circuit board. Example applications include transformers, connectors, semiconductors and electrolytic capacitors.
Other advantages to using through hole-mounted components include the compact design to decrease the component’s footprint on the circuit board, exceptional shock and vibration resistance, low frequencies and options for industrial temperature ranges and excellent aging and component longevity and durability.
