The HC-49USSX is a low-profile 2.3 mm maximum height through-hole quartz crystal designed for stable frequency operation in electronic circuits. It supports frequencies from 3.570 to 50.000 MHz, with load capacitance specified in the part number, and operates within a temperature range of -10 to +70 °C. Frequency tolerance is ±30 ppm at +25 °C, and frequency stability is ±50 ppm over the operating range. Maximum drive level is 500 μW, shunt capacitance is 5 pF, and it uses fundamental mode up to 30.000 MHz and third overtone above. The device is RoHS compliant, has MSL 1 moisture sensitivity level, and features a resistance weld construction. Aging is ±5 ppm maximum 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.
