The ECS-120-S-4X is a through-hole quartz crystal in the HC-49USX series, designed for stable frequency reference in electronic circuits. It uses a low-profile resistance weld package with 3.5 mm lead spacing. The part operates from -10 to +70°C with a frequency stability of ±50 ppm and a frequency tolerance of ±20 ppm at +25°C. It supports a 12.0 MHz operating frequency with a maximum equivalent series resistance of 60 Ω in fundamental mode. The device has a shunt capacitance of 7 pF, a drive level of 500 μW, and an aging rate of ±5 ppm over the first year at +25°C. The storage temperature range is -55 to +125°C, and it has a moisture sensitivity level of 1. The solder profile allows up to two cycles with a peak temperature of +260°C for no more than 10 seconds.
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.
