The ECS-120-18-4X-DU is a through-hole quartz crystal in the HC-49USX series, designed for stable frequency oscillation in electronic circuits. It features a low-profile resistance weld package with dimensions consistent with the HC-49USX format and uses 18 pF load capacitance. The part operates within a temperature range of -55 to +125°C, complies with RoHS standards, and has a maximum drive level of 500 μW. It supports a nominal frequency of 12.000 MHz in fundamental mode with a maximum equivalent series resistance of 60 Ω. The crystal is rated for MSL 1 and has an aging specification of ±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.
