Model
0175M4-25.000F18DTNLL
Category
The HCI 0175M4-25.000F18DTNLL is a 25MHz SMD crystal optimized for precision timing in consumer electronics and communication devices. With ±10ppm tolerance at 25°C and ±20ppm stability, it meets stringent communication standards while its 18pF load capacitance and 30Ω ESR require careful layout planning. Designed for -40°C to +85°C operation, it is ideal for IoT and automotive applications requiring compact timing solutions but lacks extended industrial temperature support.
