Document: SP0102N Last Revision Date: 09-2003 Product Specification: SP0102 Series (Generation II) This document applies the following SiSonic Model Numbers: SP0102NC3-2 SP0102NC3-3 SiSonic microphone was developed as a cost effective alternative to traditional electret condenser microphones. Provided on tape-and-reel, SiSonic is ideally suited for high volume applications. It can be processed directly to a customer’s PCB using standard automatic pick-and-place equipment, and surface mounted via standard solder reflow equipment.
