  1. OVERCURRENT PROTECTION ROADMAP P14 Committee

  2. How did we get to where we are?? DEVICES • Fuses • PTC

  3. How did we get to where we are?? TRADITIONAL FUSE CONSTRUCTION – Wire in Air

  4. How did we get to where we are?? Axial leaded of existing product ¼ x 1-1/4 inch 5 x 20 mm Miniaturization New smaller dimension axial lead Surface Mount

  5. How did we get to where we are?? TYPES OF FUSES • Elements • Thin Film • Thick Film • Multilayer

  6. How did we get to where we are?? PTC • Ceramic • Since the 1960’s • Polymer • Since the 1980’s • Circuits can be built to cut-off current

  7. Overcurrent Protection RoadmapSTATUS • Physical Size Range • 0402 • 13/32 “ • Voltage Range • 24 V • 600 V • Current Range • 2 mA • 60 A

  8. Overcurrent Protection RoadmapISSUES • Alarm indication • Arcing • Venting • Environmental • Lead-free and other substance bans • Higher process temperatures

  9. Overcurrent Protection RoadmapTRENDS/EVOLUTION • Smaller • Less expensive • Higher Energy Density • Higher Precision • 100 +/- 5% • Higher Voltage Ratings • Lower Voltage Ratings • New Ceramics

  10. IPD RoadmapSpace savings CSP 32 Ball/1mm pitch: 71.3% less area than 0805 QSOP 16 pin Isolated: 60% less area than 0805 0603 Chip resistors: 53% less area than 0805 0805 Chip resistors
