The ECS-245.7-20-4VX is a low-profile (2.3 mm max.) through-hole quartz crystal for frequencies up to 50.000 MHz, with a load capacitance of 20 pF and a frequency tolerance of ±20 ppm at +25°C. It operates from -10°C to +70°C, has a maximum drive level of 500 μW, and meets RoHS compliance standards. The part is rated for MSL 1 and uses a resistance weld construction. For the 24.576 MHz frequency, the equivalent series resistance is 100 Ω in third overtone mode. It is packaged in a HC-49USSX format with a solder profile peak temperature of +260°C for up to 10 seconds, over two cycles max.
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.
