SP0102NC3-2

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.

(IEC 68-2-4), Microphone unit must maintain sensitivity after storage at +105ºC for 1,000 hours. (IEC 68-2-2 Test Ba) Microphone unit must maintain sensitivity after storage at –40ºC for 1,000 hours. (IEC 68-2-1 Test Aa) Microphone unit must operate within sensitivity specifications for 16 hours at 105ºC. (IEC 68-2-2 Test Ba) Microphone unit must operate within sensitivity specifications for 16 hours at –40ºC. (IEC 68-2-1 Test Aa) Tested under Bias at 85ºC/85% R.H. for 270 hours. (JESD22-A101A-B) Microphone unit must operate under test condition: 4 cycles, from 20 to 2,000 Hz in each direction (x,y,z), 48 minutes, using peak acceleration of 20g (+20%, -0%). (MIL 883E, method 2007.2, A) Tested to 8kV direct contact discharge or 15kV air discharge as specified by IEC 1000-4-2, level 3 and level 4. Microphone is tested to 5 passes through reflow oven, with microphone mounted upside-down under conditions of 260ºC for 30 seconds maximum. Tested to greater than 5,000g (IEC 68-2-27, Ea). After test conditions are performed, the sensitivity of the microphone shall not deviate more than 3dB from its initial value.
