Designed to withstand reflow soldering temperatures and mechanical vibration, making it ideal for automotive "under-the-hood" or industrial sensor applications.
In some industrial settings, 9E102 is used as a document reference for crane control wire markings
If you are looking for specific application notes, I can check if the user guide provides more information. If you're designing a board, I can also help find the typical PCB layout or recommended external component values for different input/output voltages. Let me know what you need. DC/DC Converter Application Information
ROHM offers a family of synchronous buck converters with similar footprints but different specifications. When you search for “9e102 datasheet,” you may encounter these other parts.
Enable pin. High enables the IC, Low sets it to standby. 4. Typical Application Circuit 9e102 datasheet
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
In UK legislation, “9E102” appears as a technical note identifier related to . The classification specifically states: “In 9E102 ‘UAV’ means unmanned aerial vehicle systems capable of a range exceeding 300 km”. If your application involves aerospace or defense, you must check for this regulatory context. However, this is not related to the semiconductor device.
The SOP-J8 package has a on the pin 1 side. ROHM datasheets provide detailed mechanical drawings showing the orientation. Some distributors also provide PCB footprint and symbol resources for CAD tools like DesignSpark PCB.

The chip feels excessively hot to the touch (above 45°C) within seconds of power application.
Each time Mara grafted the module into some failing thing, it asked back—not in language but in cost. The device would yield a memory to restore function, and in exchange would keep a shadow of the restored system inside itself. It remembered the camera shutter by the click of the photographer’s wrist; it remembered the synth’s human breath by a scraped scale; it remembered the lullaby by humming it back in a key slightly off. It did not ask permission. It could not ask permission—its architecture only allowed exchange, not consent—so the debt settled quietly: things that started working again left a smell or a single, precise omission in the life they resumed.

Sometimes, when the light hit the bench right, the ceramic on the shelf would gleam as if the amber pin were still breathing. She would close her eyes and remember the child on the swing and the mapmaker hiding his shore. She had no way of knowing where 9e102 had gone or whether it would wake to stabilize a turbine or a lullaby. She only knew that the world had been subtly altered by a small object that treated memories as a currency of function.
The 9E102 is ideal for applications requiring precise, repeatable time delays without complex clocking or microcontrollers.
Assuming the 9E102 is a with a total delay of 102 ns, the typical electrical and environmental specifications are:
The loop bandwidth is typically optimized around 22.4 kHz to manage load fluctuations efficiently. 5. Pin Configuration and Functions Enable pin
