The ECS-184-18-1X is a through-hole quartz crystal for timing applications, based on the HC-49UX series with a frequency of 18.432 MHz, fundamental mode, and 20 pF load capacitance. It operates from -10°C to +70°C with a frequency stability of ±30 ppm and a total frequency tolerance of ±30 ppm at +25°C. The maximum drive level is 1.0 mW, shunt capacitance is 7 pF, and equivalent series resistance is 70 Ω. The package is a standard HC-49UX through-hole case with dimensions conforming to the series layout, rated for MSL 1, RoHS compliant, and PB free. The part is designed for reliable aging performance with a typical first-year drift of ±5 ppm.
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.
