ECS ECS-CTA SMD Ceramic Resonators feature a low-cost frequency control solution when absolute frequency accuracy is not crucial. The resonators are RoHS compliant and have a surface-mountable 6mm x 3mm package. The ECS ECS-CTA SMD Ceramic Resonators offer an extended -25°C to +85°C operating temperature range, a 2MHz 12MHz frequency range, and a 30Ω to 100Ω resonant resistance.
