The ECS-221-S-1X is a through-hole quartz crystal conforming to the HC-49UX series, designed for stable frequency generation in electronic circuits. It features an "AT" cut, operates over a temperature range of -10 to +70°C, and supports frequencies up to 100 MHz with a specified load capacitance. The part has a shunt capacitance of 7 pF, a maximum drive level of 1.0 mW, and complies with RoHS standards. Its physical package is the HC-49UX housing, with soldering profiles rated for peak temperatures up to 260°C for 10 seconds. The part is MSL 1 rated and uses a matte Sn/Cu lead finish. For the 22.1184 MHz frequency, the maximum ESR is 25 Ω in fundamental mode.
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.
