The ECS-250-20-46X is a through-hole quartz crystal operating at 25.000 MHz with a load capacitance of 20 pF, designed for compact circuit board layouts with a reduced footprint compared to HC-49USX. It operates within a temperature range of -10°C to +70°C, maintains frequency stability of ±50 ppm across that range, and has a frequency tolerance of ±30 ppm at +25°C. The crystal supports fundamental mode oscillation, has a maximum drive level of 100 μW, and a shunt capacitance of 7 pF. The equivalent series resistance is 50 Ω maximum. It is RoHS compliant, features a matte Sn/Cu lead finish, and is rated MSL 1. Soldering requires a peak temperature of +260°C for no more than 10 seconds, with a maximum of two cycles.
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.
