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.
