9e102 Datasheet //free\\ [Newest ✓]

most commonly refers to the Rohm Semiconductor BD9E102FJ , a synchronous buck switching regulator. Technical Specifications

| Step | Action | |------|--------| | 1. Check Physical Marking | 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. | 9e102 datasheet

EN: Enable pin; 2.0V+ turns it on, 0.8V or less enters shutdown. AGND: Ground for control circuits. FB: Feedback pin used to set the output voltage. Common Applications and Failure Symptoms most commonly refers to the Rohm Semiconductor BD9E102FJ

Pins: 8 pins total, with Pin 1 typically marked by a dot or notch. Capacitors usually have top markings; ICs have multiple pins

The 9E102 (often fully identified as the BD9E102FJ) is a synchronous buck switching regulator designed by ROHM Semiconductor. Its standout feature is its high efficiency at light loads, achieved through a proprietary control technology called Simple Light Load Mode (SLLM™). Core Technical Features
