Component library is free to design customers
TDK and Ansoft Corporation have announced the release of a new library for TDK's capacitor, inductor, common mode filter, and ferrite bead components for use in Ansoft Designer.
Wire-wound inductors go lead-free
The NLV32 and NLCV32 SMD are lead-free wire-wound inductors for signal lines.
The components are among the world's smallest (1.4 x 1.0mm).
The new array chip varistor is designed to replace the traditional combination of a Zener diode and a capacitor, resulting in a reduction in the number of parts.
This means that engineers benefit from a reduced total footprint and reduced mounting costs.
As well as being smaller, the array chip varistors offer improved electrostatic absorption capability, by providing low capacitance values (3.3-60pF).
The new range can withstand high static electricity voltage, making it the ideal solution for ESD suppression in handheld devices, as well as applications such as automotive and audio/video.
The components boast no polarity, due to symmetrical current-voltage characteristics, and they retain these symmetrical current-voltage characteristics even after electrostatic absorption.
The array chip varistors are equivalent to anode common type Zener/TVS diodes but their response is as good or better than these diodes.
The lead-free AVR-M 14A2 series is an array type varistor with two integrated chips in a 1410 package.
The nickel barrier and tin plating result in excellent mounting characteristics.
The varistors achieve good solderability and solder heat resistance, and are ideal for lead-free soldering.
