Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm part number accuracy against official TDK documentation. Check for obsolete status indicators as availability may be limited. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Validate compatibility with existing PCB footprint and reflow profiles.

Selection Notes

Evaluate frequency stability requirements against the ±0.2% specification. Consider thermal environment constraints within the -40°C to +85°C operational range. Assess circuit impedance matching needs relative to the 40 Ohm load impedance. Verify space limitations for the specific SMD package dimensions. Compare performance characteristics with alternative resonator types if higher precision is required.
