Johanson Technology uses a number of suffixes in their numbering system for RF/Balun products that are not easily found in the product datasheets, so here’s some clarification on a common question.
What does the suffix “001” such as in Johanson part number 1720BL15A0100001E call out?
Answer: The additional “001” in the suffix calls out commercial/standard product instead of automotive certified product. The manufacturer has a part numbering document available that shows the complete breakdown here: Integrated Passives Part Number Guide | Johanson Components
