The HC-49USX is a low-profile through-hole quartz crystal designed for stable frequency application. It has a frequency range of 3.570 to 70.000 MHz, a shunt capacitance of 7 pF, a drive level of 500 μW, and operates from -10°C to +70°C. Frequency tolerance is ±30 ppm at +25°C, and frequency stability is ±50 ppm across the operating temperature range. Load capacitance is specified in the part number, with options for 10 or 20 pF. Equivalent series resistance varies from 30 Ω to 200 Ω depending on frequency and oscillation mode, with fundamental mode up to 30.000 MHz and third overtone for 27.000 to 70.000 MHz. It is RoHS compliant, has MSL 1, and uses a resistance weld package. Maximum solder temperature is +260°C for 10 seconds max, with two cycles allowed.
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.
