The ECS-31X series comprises through-hole tuning fork crystals designed for low-frequency applications between 30 kHz and 150 kHz. The package measures 2x6 mm and operates over a temperature range of -10°C to +60°C with a turnover temperature of +25°C. The load capacitance is specified as 12.5 pF, with an equivalent series resistance of 50 kΩ and a drive level of 1.0 μW. Frequency tolerance at +25°C is ±30 ppm, and aging over the first year is ±5 ppm. The crystals are RoHS compliant, with an insulation resistance of 500 MΩ at 100 V DC and a soldering profile peaking at 260°C for 10 seconds. MSL rating is 1 with Sn/Cu matte lead finish.
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.
