ECM SMD Mini Spring Coils ACS C/D Series The ACS-C/DB range of surface mount spring coils offers design engineers high ‘Q’ over a uniquely wide frequency range. The flat moulded flat top make these parts ideal for fully automated pick and place production, thus increasing manufacturing productivity beyond that capable using conventional through hole coils.
