Abstract: 본 발명은 사용 주파수가 높은 회로의 콘덴서에 적합한 소용량의 온도 보상용 자기 유전체 조성물에 관한 것으로, 좀 더 구체적으로는 (1-X)·BaNd 2 Ti 5 O 14 -X·MgTiO 3 의 조성식에서 0.05≤X≤0.3의 범위를 갖도록 제조한 것이다.  종래의 경우, 온도계수가 작으면 유전율이 16∼40으로 낮고, 유전율이 조금이 높으면 온도계수가 EIA규격의 COG특성을 벗어나는 단점들을 개선하여 본 발명에서는 70∼93의 높은 유전율 값을 가지며 유전율의 온도특성 즉, EIA규격의 COG특성도 만족시키며, 유전손실값도 상당히 낮은 온도 보상용 자기 유전체 조성물을 제조하였다.
