Overview
The M83421/01-1291P hermetically sealed capacitor is a metallized plastic film capacitor in the CRH01 style, manufactured to MIL-PRF-83421/1 established reliability specifications. With a capacitance of 3µF and rated working voltage of 30V DC/AC, this component combines compact axial construction with hermetic sealing in a metal case, making it suitable for high-reliability applications requiring long service life and stable performance across temperature ranges.
Key Features
- Hermetically sealed metal case for environmental protection and moisture resistance
- Metallized plastic film dielectric ensures stable capacitance and low dissipation
- Tight ±1% tolerance for precision circuit tuning and filtering
- Axial through-hole leads (CRH01 configuration) for standard PCB assembly
- Established reliability designation per military specification MIL-PRF-83421/1
- Suitable for both DC and AC applications in industrial and aerospace systems
Technical Specifications
The capacitor is rated for 30V DC/AC operation with a capacitance value of 3µF and a tolerance of ±1%. Its hermetically sealed construction protects against moisture ingress and environmental contamination. The axial lead configuration (CRH01 style) simplifies installation in through-hole designs. The metallized plastic film construction provides low equivalent series resistance (ESR) and good frequency response.
