9e102 Datasheet [new] 99%

Wide input voltage capability of 7.0V to 26V.

The BD9E102FJ itself appears to be , as indicated on major distributor websites. However, the BD9E102FJ-GE2 variant is still listed as active by some suppliers. Engineers are advised to check ROHM’s official product lifecycle status and consider the BD9E103FJ or BD9E300EFJ series as potential alternatives if the BD9E102FJ is unavailable.

| Step | Action | |------|--------| | | Is the component a black IC, a brown/yellow capacitor, or a gray inductor? Capacitors usually have top markings; ICs have multiple pins. | | 2. Identify Manufacturer Logo | Look for a logo (e.g., Murata = diamond, TDK = boxed letters). This is critical. | | 3. Search with Wildcards | Use Google or Octopart: "9e*102" capacitor , "9E102" marking , or "series 9E" datasheet . | | 4. Use Parametric Search | If you know it's a 1000pF cap, go to Mouser/DigiKey, filter for 1000pF, voltage, package, and compare photos. | | 5. Decode per Manufacturer | - Murata : "9E" often appears in GRM series caps (e.g., GRM188R71H102KA01 – but that’s different). - TDK : "9E" might be a lot code. - AVX : "9E" seen on some military-grade X7R caps. |

In 99% of cases, it is a 1000 pF ceramic capacitor . However, some obsolete Japanese transistors (e.g., 2SC series) used a "9E" prefix. Always examine the component: if it is beige/black and non-polar, it’s a capacitor. If it is a black plastic 3-lead device, check for "9E 102" as a date code, not a part number.

Engineers should ensure adequate PCB copper area for heat sinking, particularly when operating at high input voltages and near the full 1A output current.

Suitable for any device requiring a 1A step-down converter with a small SOP-8 footprint. Sourcing and Documentation

user wants a long article about "9e102 datasheet". This appears to be an electronic component. I need to provide a comprehensive guide. My search strategy involves casting a wide net to identify the component and gather technical specifications. I will perform multiple searches to cover datasheet sources, specifications, applications, alternatives, and purchasing information. search results show multiple references to "BD9E102FJ" from ROHM. This seems to be the correct component. I also see references to "9E102 SOP-8" which might be a marking code. I need to open the relevant pages to gather detailed technical information. search results point to the BD9E102FJ, a step-down DC/DC converter from ROHM. There's also a "9E102 SOP-8" which seems to be a different component, likely a marking code. I will structure the article with an introduction, a key section clarifying the identity of "9E102", then cover the BD9E102FJ datasheet in detail, including its manufacturer, key features, technical specifications, application circuits, equivalent parts, and procurement. I will also address the "9E102 SOP-8" component and the EU dual-use regulation. 9e102 Datasheet: Complete Technical Guide to ROHM BD9E102FJ Step-Down DC/DC Converter
