Procurement Notes

Verify that the specific application requires the defined 5k/20k primary and 60k secondary impedance configuration. Confirm mechanical clearance for the specified dimensions and base mounting style. Ensure the operating environment remains within standard temperature limits to maintain electrical stability. Cross-reference datasheet specifications against system requirements before finalizing procurement decisions.

Selection Notes

Select this model when precise impedance transformation between 5k or 20k primary sources and 60k secondary loads is required. Consider the physical footprint constraints regarding the 44.45mm by 30.48mm base area. Evaluate the need for wire lead termination versus other connection methods. This component suits designs prioritizing analog signal integrity over digital switching frequencies.
