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.
