9e102 Datasheet !!top!! -

Regarding the 9E102 (likely a model number for a crystal oscillator or quartz crystal unit from NDK or a similar frequency control component), here are the most useful features typically found in its datasheet:

  1. Fundamental Frequency Range – Usually specifies the exact nominal frequency (e.g., 10.000 MHz, 12.288 MHz, etc.) and whether it's fundamental mode or overtone.
  2. Frequency Tolerance & Stability – Key for timing accuracy: typical values like ±20 ppm, ±30 ppm, ±50 ppm at 25°C, and stability over temperature (e.g., ±30 ppm from -20°C to +70°C).
  3. Operating Temperature Range – Commercial (0°C to +70°C), industrial (-40°C to +85°C), or automotive-grade options.
  4. Load Capacitance (CL) – Critical for proper oscillation; common values: 10 pF, 12 pF, 16 pF, 18 pF, 20 pF.
  5. Equivalent Series Resistance (ESR) – Maximum ESR value at the given frequency (lower is better for start-up margin).
  6. Drive Level – Typical maximum (e.g., 100 µW or 500 µW) to avoid overdriving and frequency shift.
  7. Package / Case Style – Likely a small SMD package (e.g., 3.2×2.5 mm, 5×3.2 mm, or HC-49/US). The 9E series is often a compact SMD crystal.
  8. Aging Rate – Long-term stability (e.g., ±3 ppm to ±5 ppm per year).
  9. Shunt Capacitance (C0) – Important for oscillator circuit design (typically 3–7 pF).
  10. RoHS / REACH Compliance – For environmental regulatory requirements.

⚠️ Note: There is no standard “9E102” part number across major vendors like NDK, ECS, TXC, or Abracon. It could be a custom or obsolete part, or a misreading (e.g., 9E102 could be a date/lot code or partial number).
To get the actual datasheet:

  • Check the full marking on the component.
  • Search for “9E102 crystal datasheet” on Mouser, DigiKey, or Octopart.
  • Look for a manufacturer logo (NDK, Murata, Epson, etc.).

If you provide the manufacturer name or a photo of the component marking, I can narrow down the exact datasheet and its most useful specifications. 9e102 datasheet

2.3 Absolute Maximum Ratings

| Parameter | Limit | |-----------|-------| | Operating Temperature | -55°C to +125°C | | Storage Temperature | -55°C to +125°C | | Soldering Temperature (Peak) | +260°C for 10 sec (max) | | Voltage (DC) | Do not exceed 50V (or 100V) | | Humidity | 85% RH at 85°C for 1000 hrs | Regarding the 9E102 (likely a model number for

Warning: Exceeding voltage or temperature may cause catastrophic failure (cracking or shorting). X7R capacitors exhibit microphonic effects under mechanical stress.

Q2: What is the tolerance of the 9E102?

A: Without the full datasheet suffix, assume ±10% (K tolerance). If the original marking includes a letter after 102 (e.g., "9E102K"), the K indicates ±10%. J = ±5%, M = ±20%. Fundamental Frequency Range – Usually specifies the exact

3.4 Snubber Circuit for Relays

Use a 9E102 in series with a 100 Ω resistor across relay contacts or a triac to suppress voltage spikes (dI/dt). For 24V AC or DC circuits, the 50V rating is sufficient. For 110V AC, select the 100V variant.
