If you cannot source the exact 9E102 from AVX or Murata, here are direct equivalents:
| Manufacturer | Part Number | Capacitance | Voltage | Dielectric | Package | |--------------|-------------|-------------|---------|------------|---------| | AVX | 06035C102KAT2A | 1000 pF ±10% | 50V | X7R | 0603 | | Murata | GCM188R71H102KA37 | 1000 pF ±10% | 50V | X7R | 0603 | | KEMET | C0603C102K5RACTU | 1000 pF ±10% | 50V | X7R | 0603 | | TDK | C1608X7R1H102K | 1000 pF ±10% | 50V | X7R | 0603 | | Yageo | CC0603KRX7R9BB102 | 1000 pF ±10% | 50V | X7R | 0603 |
Note: The marking on equivalents may read "102" or "102K" instead of "9E102". The '9E' prefix is specific to a few Asian manufacturers and older batches. 9e102 datasheet
Very often, the full part number is printed across two lines or has suffix letters that matter. For example:
| Parameter | Value | Notes | |-----------|-------|-------| | Capacitance | 1000 pF ±5% or ±10% | Code 102 = 1000 pF | | Rated Voltage | 50V DC (or 100V DC for high-voltage variant) | Some '9E' codes indicate 100V | | Dielectric | X7R (Class II) | Stable from -55°C to +125°C | | Temperature Coefficient | ±15% over temperature range | ΔC/C max from 25°C | | Dissipation Factor (DF) | ≤ 2.5% at 1 kHz, 1Vrms | Typical for X7R | | Insulation Resistance (IR) | ≥ 10,000 MΩ or 100 MΩ·µF | Whichever is less | | Dielectric Withstanding Voltage (DWV) | 250% of rated voltage for 5 sec | 125V DC for 50V part | | Aging Rate | 2.5% per decade hour | Typical for X7R | If you cannot source the exact 9E102 from
In op-amp circuits (e.g., non-inverting amplifier), a 9E102 placed in parallel with the feedback resistor reduces high-frequency gain and prevents oscillation. For a gain of 10, with Rf = 10 kΩ, the 1 nF cap creates a pole at ≈ 16 kHz.
MOSFETs like the 9E102 are used in a wide range of applications, including: Note: The marking on equivalents may read "102"
The 9E102 is ideal for applications requiring precise, repeatable time delays without complex clocking or microcontrollers.
"102" often means 1000 pF (0.001 µF). The "9E" might be a voltage or dielectric code (e.g., 9E = 25V in some older Kemet systems). You may have a ceramic capacitor marked "9E 102" or "102 9E".
