The HC-49USX-DN is a through-hole quartz crystal designed for industrial temperature range applications, operating from -40°C to +85°C with a frequency stability of ±100 ppm over that range. It features a standard HC-49USX footprint, RoHS compliance, and operates at frequencies up to 70.000 MHz, with a maximum drive level of 500 μW and shunt capacitance of 7 pF. Load capacitance is user-specified, and modulation modes include fundamental for frequencies up to 30.000 MHz and third overtone for 27.000 to 70.000 MHz. The part supports solder peak temperatures up to 260°C for 10 seconds, with MSL 1 rating and matte Sn/Cu lead finish.
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.
