The ECS-184-S-1X is a through-hole quartz crystal oscillator designed for stable frequency reference in electronic circuits. It uses an "AT" cut crystal with a frequency of 18.432 MHz, operates within a temperature range of -10 to +70°C, and has a load capacitance of 20 pF. The package is HC-49UX, measuring approximately 12.7 mm in length and 4.7 mm in diameter. It supports fundamental mode oscillation with a maximum ESR of 70 Ω, a drive level of 1.0 mW, and a shunt capacitance of 7 pF. The part meets RoHS compliance, has a storage temperature range of -55 to +125°C, an aging rate of ±5 ppm over the first year, and is rated MSL 1 for moisture sensitivity. Soldering must not exceed +260°C for more than 10 seconds, with a maximum of two cycles.
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.
