The ECS-143-20-4VX is a through-hole quartz crystal oscillator with a frequency of 14.31818 MHz, a load capacitance of 20 pF, and a low-profile resistance weld package measuring 2.3 mm maximum height. It operates within -10 to +70 °C, with a frequency tolerance of ±30 ppm at +25°C and stability of ±50 ppm across the temperature range. The maximum drive level is 500 µW, and the shunt capacitance is 5 pF. It meets RoHS standards, has an MSL rating of 1, and uses a Sn/Cu matte lead finish. The ESR is 40 ©Ω at the fundamental mode of oscillation.
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.
