Microphone Capsule KRUPS MCE-4001, diameter 6 mm

KRUPS MCE-4001 is a replacement microphone capsule with a 6 mm diameter designed for use in small-diaphragm microphones, headsets and compact handheld devices. The capsule functions as the core transducer element for capturing acoustic signals and is intended for repairs, custom microphone builds or OEM replacements where a compact electret-style or similarly sized capsule is required. The product name and physical size make it suitable when an exact small form factor is necessary for fit and acoustic integration.

Advantages

The 6 mm capsule offers a compact footprint that enables installation in tight housings and lightweight assemblies. It provides consistent acoustic pickup suitable for voice and near-field sound capture. As a replacement component, the capsule allows restoration of microphone function without replacing the entire device and supports custom projects where space and weight constraints are important. The design is compatible with common small-diaphragm mounting arrangements and wiring practices used in headsets and portable recorders.

Suitable for

• Repairing small-diaphragm microphones and headsets
• Custom microphone builds and prototypes
• Replacement in compact handheld audio devices
• OEM applications requiring a 6 mm electret-style capsule

Key specifications

• Transducer type: small-diaphragm microphone capsule (electret-style compatible)
• Diameter: 6 mm
• Form factor: compact capsule for tight housings
• Typical use: voice and near-field acoustic capture
• Compatibility: suitable for headset, handheld and small condenser microphone assemblies

How to use

When replacing an existing capsule, first verify mechanical fit and pinout compatibility with the host device. Power the capsule according to the original device’s requirements—electret-style capsules typically require a bias voltage provided through the microphone input or preamp. Secure the capsule in the housing to avoid movement or rattling and route wiring to prevent contact noise. After installation, perform a functional check and basic audio test to confirm sensitivity and polarity are correct before final assembly.

Usage recommendations

Ensure correct biasing and wiring before applying power, and verify physical clearance inside the housing to avoid mechanical interference. For repairs, compare acoustic response and mounting orientation with the original capsule to maintain consistent sound characteristics. Use appropriate ESD precautions during handling and solder connections rated for small component work.
