Technical Specifications

Our 6050 plug-in microphone head is an omnidirectional electret transducer featuring built-in dual capacitors for effective RF interference shielding. It is produced using imported JFET and eco-friendly materials, ensuring high performance and sustainability.

Standard Test Circuit

Test conditions: RL = 2.2kΩ, Vs = 2V, C = 1μF

Typical Frequency Response

The frequency response spans 50Hz to 20kHz. It remains flat from 50Hz to 3kHz, then rises between 3kHz and 6kHz to improve vocal presence. After 6kHz, the response begins to roll off steadily toward higher frequencies.

Dimensions (UNIT: mm)

Appearance Dimension

Capsule dimensions: 6.0mm diameter × 5.0mm height. The front face features a dustproof mesh, while the back is sealed with no acoustic port. Equipped with 4.5mm pins, with 1.9mm spacing.

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℃.
