NAP Series — Thin Film Precision Chip Resistor

Writer:Microhm Page View:Date:2019-06-27
As the increased demands for precision and stability, Microhm has expanded its thin-film chip resistors NAP Series into three sectors, Standard, High-Precision, and High-Power.
 
The series benefits from an impervious internal passivation layer applied in addition to the normal protective coating. When constructing the NAP Chip Series, a Ni/Cr thin-film material is selectively deposited on an alumina substrate, together with Ni and Sn metallic contacts at each end layer plating. The NAP chips are heat treated to give the required temperature coefficient (TCR) and stability, and then a precisely controlled laser trim process adjusts the resistance value. NAP series, ROSH compliant and lead free, is available in taping packaging.

Offering a wide chip size, resistance value range with closer tolerances and low TCR figures, Microhm offers a surface mount resistor with a defined total contour whose size from 0201 to 2512 that provides high stability under temperature fluctuations of 1ppm/°C and with a tolerance down to ± 0.01%, tolerance range from 1 ohm to 3 Ms.

 
 
The thin film precision chip resistor NAP Series offering solutions to precision test and measurement and voltage regulation across medical monitoring equipment markets, industrial, and consumer electronics demanding tight tolerance, low TCR, and high power rating performance.
