Technical Write-Up: Decoding the "9e102" Datasheet Reference

According to technical listings from retailers like UTSource and Mouser, the operates within the following parameters:

Input Voltage Range

: Supports a broad range from 7.0V to 26V .

This guide serves as a definitive resource, whether you are replacing a faulty part, designing a new PCB, or reverse-engineering a vintage device.

Mara kept repairing, slowly, with a different sort of care. She refused more than before. She taught apprentices the lesson the module had taught her: that repair is not only technical; it is ethical. She taught them how to name what they took, how to leave a record of what they restored, how to make small gestures of permission where machines could not.

too large

Many microcontroller datasheets (e.g., ATmega328P, STM32) require a 12-22 pF load capacitor for 16 MHz crystals. The 9E102 is for that role. However, it is used in parallel with a crystal as a DC blocking capacitor in Pierce oscillators for low-frequency crystals (32.768 kHz). Verify with your MCU’s datasheet.

Wide Input Voltage Range

: Operates from 7.0V to 26V , making it suitable for 12V and 24V bus systems commonly found in consumer electronics and adapters.

• Some inductor series (e.g., from Coilcraft or Bourns) use a 2-letter + 3-number code. 102 = 1000 µH or 1000 nH (1 mH or 1 µH).
• "9e" might be a size or material code (e.g., 9 = EIA size 0805, e = ferrite material).
