Risks and Uncertainties [Abstract]
Concentrations of Risks	Concentrations of Risks The Company sells to customers globally and, as the Company generally does not require collateral from its customers, on a monthly basis the Company evaluates customer account balances in order to assess the Company’s financial risks of collection. One customer, TTI, Inc., an electronics distributor, accounted for over 10% of the Company’s net sales in the quarters and six-month periods ended September 30, 2016 and 2015. There were no accounts receivable balances from any customer exceeding 10% of gross accounts receivable as of September 30, 2016 and March 31, 2016. Electronics distributors are an important distribution channel in the electronics industry and accounted for 46% and 42% of the Company’s net sales in the six-month periods ended September 30, 2016 and 2015, respectively. As a result of the Company’s concentration of sales to electronics distributors, the Company may experience fluctuations in the Company’s operating results as electronics distributors experience fluctuations in end-market demand and/or adjust their inventory stocking levels.
