EK3033 Electret Condenser Microphone Capsule For Voice Pickup

EK3033 is an electret condenser microphone capsule used to capture voice and ambient sound in compact audio front ends. It’s a common fit for intercoms, handheld devices, test fixtures, and embedded systems that need a simple analog microphone source. In practice, EK3033 is paired with a bias network and a preamp stage to set gain and manage noise. Verified electrical operation supports a 0.9 V to 10 V DC supply range, which helps when the microphone bias comes from low-voltage rails. Use EK3033 when you want predictable behavior in a small footprint and a straightforward interface to an ADC or codec. Request a quote for EK3033.
