The ECS-120-20-4X is a through-hole quartz crystal in the HC-49USX series, designed for frequency stabilization in electronic circuits. It features a low-profile resistance weld package with dimensions consistent with the HC-49USX form factor. The part operates over a temperature range of -10°C to +70°C with a frequency stability of ±50 ppm and a frequency tolerance of ±30 ppm at +25°C. It has a load capacitance of 20 pF, a maximum drive level of 500 μW, and an equivalent series resistance (ESR) of 60 Ω maximum at 12.000 MHz in fundamental mode. The crystal is RoHS compliant, has an MSL rating of 1, and supports solder profiles up to +260°C for 10 seconds max. Aging is specified at ±5 ppm 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.
