The HC-49USX is a low-profile, resistance weld type thru-hole quartz crystal designed for various electronic applications. It operates at frequencies ranging from 3.570 MHz to 70.000 MHz, with a frequency tolerance of ¬±30 ppm at +25¬8C and stability of ¬±50 ppm over a temperature range of -10¬8C to +70¬8C. The shunt capacitance is specified at 7 pF, and the load capacitance can be specified in the part number, typically around 20 pF. The drive level is rated at 500 OºW, making it suitable for low-power applications. This crystal is RoHS compliant and features a moisture sensitivity level (MSL) of 1, indicating it can withstand standard soldering processes. The operating temperature range is from -10¬8C to +70¬8C, with a storage temperature range of -55¬8C to +125¬8C. Aging is specified at ¬±5 ppm for the first year at +25¬8C. The HC-49USX is available in various frequency options and packaging configurations, allowing for flexibility in design.
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.
