Technical Specifications

Our 6050 microphone capsule, featuring soldered 1.25 terminals and a 40mm wire length, offers full-directionality, making it ideal for high-quality microphone applications.

Standard Test Circuit

Test conditions: Load resistor (RL) = 2.2kΩ, Supply voltage (VS) = 3V, Coupling capacitor (C) = 1μF.

Typical Frequency Response

The frequency response spans 50Hz to 20kHz. The curve remains mostly flat from 50Hz up to around 3kHz, where a noticeable rise begins, peaking near 10kHz before gradually declining.

Dimensions (UNIT: mm)

Appearance Dimension

Diameter: 6mm; Height: 5mm. Front side features a dustproof mesh, back side is sealed with no holes. Equipped with 45mm twisted-pair soldered leads.

Packaging Overview

Standard packaging: 100 pcs per small box.
10 small boxes (1,000 pcs) are combined into one medium carton.
Several medium cartons are further packed into a large outer carton.
Pin-type microphones are protected with foam inside the small box.
Other types are packed directly or sealed in anti-static bags.

Reliability Tests

High Temperature Test: Microphone subjected to +80℃ for 100 hours, followed by 3 hours at room temperature.

Low Temperature Test: Microphone subjected to -40℃ for 100 hours, followed by 3 hours at room temperature.

Humidity & Heat Test: Microphone exposed to +55℃ and 85% relative humidity for 100 hours, followed by 3 hours at room temperature.

Thermal Shocking Test: Microphone subjected to [+80℃ 0.5H → room temp 1H → -40℃ 0.5H → room temp 1H] for 10 cycles, then exposed to room temperature for 3 hours.

Vibration Test: Microphone subjected to two hours of vibration in x, y, and z directions with frequencies of 10-55Hz and a 1.52mm amplitude.

Drop Test: Microphone dropped 5 times from a height of 1.0 meter onto a slippery marble floor, without packaging, and still performs normally.

Storage and Operating Temperature Range: Suitable for environments ranging from -35℃ to +60℃.
