Niobium Oxide Capacitors Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as this part number may be subject to discontinuation notices or limited production runs. Confirm moisture sensitivity level (MSL 3) handling requirements prior to assembly. Ensure that the specific ordering suffix matches the required packaging configuration, such as reel or cut tape, to align with automated placement equipment specifications.

Niobium Oxide Capacitors Selection Notes

Select this component when high capacitance density is required in a 2917 footprint. The 6.3V rating and 400mOhm ESR make it suitable for low-voltage digital logic decoupling. Consider the ±20% tolerance for standard filtering applications. Verify thermal management capabilities given the 612mA ripple current rating and ensure compatibility with reflow soldering profiles defined for niobium oxide devices.
