The ECS-184-S-4X is a through-hole quartz crystal in the HC-49USX series, providing stable oscillation at 18.432 MHz with series load capacitance. It operates from -10°C to +70°C with ±50 ppm frequency stability and a maximum ESR of 60 Ω in fundamental mode. Drive level is limited to 500 μW, shunt capacitance is 7 pF, and aging is ±5 ppm per year at +25°C. The package is low-profile and resistance-welded, with Sn/Cu matte leads and MSL 1 rating. It is RoHS compliant and supports solder peak temperatures up to +260°C for 10 seconds, with two cycles maximum. Storage temperature ranges from -55°C to +125°C.
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.
