The ECS-18-S-1X is a through-hole quartz crystal in the HC-49UX series, designed for stable frequency reference in electronic circuits. It features an AT-cut crystal with a frequency of 1.8432 MHz, a load capacitance of 18 pF, and operates within a temperature range of -10°C to +70°C. The part has a frequency tolerance of ±20 ppm and stability of ±50 ppm over the operating range, with a maximum drive level of 1.0 mW and shunt capacitance of 7 pF. It meets RoHS standards, has an MSL rating of 1, and uses a matte tin/copper lead finish. The package dimensions and solder profile align with standard HC-49UX specifications.
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.
