The ECS-25-S-1X is a through-hole quartz crystal in the HC-49UX package, designed for stable frequency reference in electronic circuits. It measures 12.7 mm in length and 4.8 mm in diameter, with a maximum drive level of 1.0 mW and a shunt capacitance of 7 pF. It supports frequencies from 1.800 to 100.000 MHz, with a frequency tolerance of ±30 ppm at +25°C and stability of ±50 ppm across -10 to +70°C. Load capacitance is specified in the part number. The crystal is AT-cut, with series resistance from 750 Ω at 1.8 MHz to 20 Ω at 16-30 MHz and 40 Ω for 30-100 MHz in third overtone mode. Aging is ±5 ppm over the first year at +25°C, it is RoHS compliant, has MSL 1 rating, and operates from -55 to +125°C storage temperature.
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.
