FEATURES
• Very small footprint, allowing to increase the
number of lines per PCB
• Matched pairs in one component, significantly
reducing the assembly time
• Narrow tracking between the 2 PTC’s over a wide
temperature range (matching at 85 °C: ≤ 2 x matching at
25 °C)
• Limited height and weight, used on high speed pick-andplace
circuit assembly
• Flat pick-up ceramic area for easy placement
• Small ceramics for faster response time
• Thermal coupled PTC’s for enhanced protection
• Small and large pitch available
• Compliant with the enhanced level requirements of
ITU - K20-21-45 edition 2003
• Suitable for lead (Pb)-bearing and lead (Pb)-free reflow
soldering
• Material categorization: For definitions of compliance

APPLICATIONS
Over-temperature/over-load protection:
• Telecom
- Telecommunications infrastructure
- PABX
- Set-top Box (S.B.)

DESCRIPTION
The component consists of two high performance PTC
ceramics mounted together on an alumina spacer cover and
with 4 lead (Pb)-free tin plated contacts. The terminations
are joined to the Ag plated ceramics by a high melting
solder.
