The ECS-184-20-4X is a through-hole quartz crystal with a 18.432 MHz frequency and 20 pF load capacitance, housed in a low-profile HC-49USX package measuring 3.5 mm in height. It operates within a temperature range of -10°C to +70°C, with a frequency stability of ±50 ppm over that range and a frequency tolerance of ±30 ppm at +25°C. The device supports fundamental mode operation with a maximum equivalent series resistance of 40 Ω and a drive level of 500 μW. It is RoHS compliant, has MSL 1 moisture sensitivity level, and features a solder profile peak temperature of +260°C for up to 10 seconds.
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.
