TDA Elektronic Technology has introduced lead-free versions of its CPTC series of resettable fuses.
Overcurrent protector is ceramic based
To cater the fast growth of VoIP and increasing numbers of telecommunication lines, TDA Elektronic Technology had developed a Pb-free 50ohm resettable 600V AC overcurrent protector.
Overvoltage protection devices go lead-free
Telecomms overvoltage protection devices manufactured by TDA Elektronic are now shipping 100% lead-free.
TDA CPTCs have always been known for their high performance in SLIC protection.
The resistance value set at 50ohm provides efficient overcurrent protection in telecomms applications.
The ceramic body has high impedance, making it an excellent insulator.
High voltage surge applications and thermal stability increases its reliability and service life.
The low 7ohm resistance of the CPTC series answers the growing demand to replace polymer PTC devices with better and faster solutions.
The low-resistance CPTC device is available as a single chip (AMZ2L-7R), as a two-in-one chip (TSF4L-7R) and as a surface-mount device with two-in-one chips (TSF4S-7RF) with matched resistance below 0.5ohm.
Most CPTC devices are used together with overvoltage protection devices, such as the TWEOS61089 and TWEOS6NTP series.
They can provide protection against high voltage generated by thunder and lightning, high frequency induction and lap connection of electric lines.
In addition, these devices provide manufacturing compatibility with high-volume electronics assembly techniques and greater design flexibility through a wide range of product options. Request a free brochure from TDA Elektronic Technology ...
