0175M4-9.8304F20DTNJL
Category
The 9.8304MHz SMD crystal with 20pF load capacitance and ±30ppm frequency stability is optimized for cost-sensitive consumer electronics and communication applications. Its compact SMD7050-4P package ensures easy PCB integration but requires careful thermal management and static protection during assembly. The ±10ppm room temperature tolerance and 55Ω ESR make it suitable for time-sensitive devices while maintaining competitive pricing compared to alternative models.
