The ECS-40-20-4VX is a through-hole quartz crystal with a low profile of 2.3 mm maximum, designed for stable frequency operation in electronic circuits. It operates at 40.000 MHz with a load capacitance of 20 pF and a frequency tolerance of ±30 ppm at +25°C, and maintains ±50 ppm stability over the temperature range of -10°C to +70°C. The crystal uses third overtone oscillation at this frequency, with a maximum ESR of 80 Ω and a drive level of 500 μW. It is RoHS compliant, rated MSL 1, and meets a solder peak temperature of +260°C for up to 10 seconds. Storage temperature spans from -55°C to +125°C, with an aging rate 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.
