TDA Ceramic PTC devices cut resistance for broadband

TDA has introduced a new range of high-tech protection devices with low 7ohm resistance to enhance the safety and stability performance of long distance communication applications. The new devices have the ability to support a wide transmission band and large communication capacity. TDA CPTCs have always been known for their high performance in SLIC protection.

The resistance value set at 7ohm 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.
