The ECS-122.8-20-4VX is a through-hole quartz crystal in the HC-49USSX series, designed for stable frequency applications with a low profile of 2.3 mm max. It operates at 12.288 MHz with a load capacitance of 20 pF, a frequency tolerance of ±20 ppm at +25°C, and frequency stability of ±50 ppm over the temperature range of -10°C to +70°C. The crystal operates in fundamental mode with a maximum equivalent series resistance of 60 Ω and a drive level of 500 μW. It is RoHS compliant, has MSL 1 moisture sensitivity, and supports reflow soldering with a peak temperature of +260°C for up to 10 seconds. Storage temperature ranges from -55°C to +125°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.
