TOKYO, Dec 2 Japanese smartphone parts maker TDK Corp expects to win more orders next year from a major North American customer whose high-end phones are set to carry improved features, its chief executive said, in a reference to Apple Inc and its iPhones. "Expectations for the next year are high," Takehiro Kamigama told Reuters in an interview on Wednesday, suggesting that the next-generation iPhone is expected to carry more of its high-frequency filters per handset.
