Series Reference

V-Series (with hyphen)

RE-Series (radial lead, no hyphen)

OV-Series (polymer, with hyphen)

Voltage Codes

Voltage codes appear after capacitance and tolerance codes.

Capacitance Codes

Uses 3-digit EIA code for electrolytic capacitors (value in uF):

Package Codes

Package codes are 4 digits indicating diameter x height in mm (DDLL format):

Handler Implementation Notes

Pattern Recognition

// V-series with hyphen: VE-, VR-, VZ-
"^VE-[0-9]+.*"  // Low impedance
"^VR-[0-9]+.*"  // Standard
"^VZ-[0-9]+.*"  // High temperature

// RE-series without hyphen: REA, REB, REC
"^REA[0-9]+.*"  // Radial lead A
"^REB[0-9]+.*"  // Radial lead B
"^REC[0-9]+.*"  // Radial lead C

// OV-series with hyphen: OVZ-, OVR-
"^OVZ-[0-9]+.*"  // Polymer Z
"^OVR-[0-9]+.*"  // Polymer R

Package Code Extraction

// Package code is the last 4 digits
// VE-101M1CTR-0605 -> 0605 -> 6.3x5mm

// Steps:
// 1. Check last 4 chars for numeric pattern
// 2. Map DDLL to diameter x height
String lastFour = mpn.substring(mpn.length() - 4);
if (lastFour.matches("[0-9]{4}")) {
    // Decode: 06 = 6.3mm diameter, 05 = 5mm height
}

Series Extraction

// Check prefix to determine series type
if (mpn.startsWith("VE-")) return "VE Low Impedance";
if (mpn.startsWith("VR-")) return "VR Standard";
if (mpn.startsWith("VZ-")) return "VZ High Temperature";
if (mpn.startsWith("REA")) return "REA Radial Lead";  // No hyphen
// etc.

Replacement Rules

The handler supports these replacement scenarios:

1. VE can replace VR: Low impedance can replace standard (better performance)
2. VZ can replace VR/VE: High temp can replace standard (wider temp range)
3. OVZ/OVR can replace VR: Polymer can replace standard (longer life)

Package dimensions must match for any replacement.

Learnings & Edge Cases

• Hyphen placement: V-series and OV-series use hyphen after prefix (VE-), but RE-series does not (REA)
• Package code position: Always the last 4 digits of the MPN
• Voltage code position: After capacitance (3 digits) and tolerance (1 letter)
• Tolerance codes: M=20% (most common), K=10%, J=5%
• TR suffix: Indicates tape and reel packaging
