Nippon Chemi-Con primarily uses 3-digit voltage codes where value = code / 10:
| Code | Voltage | Code | Voltage |
|---|---|---|---|
| 040 | 4V | 250 | 25V |
| 063 | 6.3V | 350 | 35V |
| 100 | 10V | 500 | 50V |
| 160 | 16V | 630 | 63V |
| 200 | 20V |
Some series use EIA voltage codes (digit + letter):
| Code | Voltage | Code | Voltage |
|---|---|---|---|
| 0G | 4V | 1V | 35V |
| 0J | 6.3V | 1H | 50V |
| 1A | 10V | 1J | 63V |
| 1C | 16V | 2A | 100V |
| 1E | 25V |
Uses standard EIA 3-digit code (value in uF):
| Code | Value | Calculation |
|---|---|---|
| 100 | 10uF | 10 x 10^0 |
| 101 | 100uF | 10 x 10^1 |
| 221 | 220uF | 22 x 10^1 |
| 471 | 470uF | 47 x 10^1 |
| 102 | 1000uF | 10 x 10^2 |
| 103 | 10000uF | 10 x 10^3 |

The handler supports replacement scenarios based on:
// Higher voltage rating can replace lower in same series
int v1 = parseVoltageCode(voltage1);
int v2 = parseVoltageCode(voltage2);
if (v1 >= v2) return true; // 50V can replace 25V
