Technical Specifications

Our 6022 omnidirectional pin microphone core features dual capacitors for anti-interference and a pin length of 2.8mm, ensuring clear audio and reliable performance.

Standard Test Circuit

Test circuit uses RL=2.2KΩ, Vs=2V, and C=1μF for standard sensitivity and performance evaluation.

Typical Frequency Response

Frequency response spans 50Hz–20kHz with a stable output and slight downward trend across the range.

Dimensions (UNIT: mm)

Appearance Dimension

Capsule measures 6.0mm in diameter and 2.2mm in height, with front dust mesh and a sealed back (no acoustic port). Equipped with 2.8mm 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℃.
