Problems solved by technology

[0011] According to the related art, a phosphoric acid-based dispersant formed of a polymer having a weight-average molecular weight of 700-2500 is used, but there are disadvantages in that the dispersibility is not enough to maintain the precipitation stability of high-density metal magnetic powder, and to prevent secondary coagulation that is powder Particles coagulate again after initial dispersion

Abstract

The invention provides a chip electronic member and a manufacture method for the same. The chip electronic member comprises an magnet. The magnet comprises an inner coil pattern which is arranged on the at least one surface of the insulation base bottom, and an outer electrode. The outer electrode is formed on at least one end surface of the magnet and is connected to the end of the inner coil pattern. The magnet comprises a unsaturated carboxylic acid base polymer. The chip electronic member has dispersibility and stability of the improvement.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2014-0027291 filed with the Korean Intellectual Property Office on March 7, 2014, the disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to a chip electronic component and a preparation method thereof. Background technique [0004] An inductor, a chip electronic component, is a typical passive device that removes noise along with resistors and capacitors in electronic circuits. Inductors are combined with capacitors using electromagnetic properties to configure resonance circuits, filter circuits, and the like that amplify signals in specific frequency bands. [0005] Currently, with the acceleration of miniaturization and thinning of information technology (IT) equipment such as various communication equipment, displays, etc., research on various devices used in these IT equipment such as induct...
