The ECS-80-20-4X is a through-hole quartz crystal in the HC-49USX package, designed for stable frequency reference in electronic circuits. It has a 3.5 mm lead spacing, operates from -10°C to +70°C, and supports a load capacitance of 20 pF. The unit is rated for a maximum drive level of 500 μW and has a shunt capacitance of 7 pF. Frequency stability is ±50 ppm over the operating temperature range, with a tolerance of ±30 ppm at +25°C. The crystal is RoHS compliant, has a maximum ESR of 80 Ω for its 8.0 MHz frequency in fundamental mode, and complies with MSL 1 for moisture sensitivity. The solder profile allows for peak temperatures up to +260°C for no more than 10 seconds, with two cycles maximum.
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.
