Technical Specifications

The ECM-B1045UL-53-L60 is a 10 × 4.5 mm unidirectional microphone capsule specifically designed for integration into systems requiring a 60 mm solder lead. With the same premium Korean-made diaphragm and acoustic performance as the ECM-B1045UL-53, this model is optimized for flexibility in assembly and installation.

Its frequency response is fine-tuned for musical instrument applications, with a smooth lift in the low frequencies for depth and body, followed by enhanced midrange clarity. High frequencies are attenuated to reduce harshness, providing a balanced and natural tone for a wide range of instruments.

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℃.

Sampling Process
