Overview
The Sprague S64036 is an oil-filled capacitor originally manufactured by Sprague Electric, now acquired by Vishay Intertechnology. This capacitor is rated at 7.0uF capacitance with a 400VDC voltage rating, making it suitable for DC bus filtering, power conditioning, and energy storage applications in legacy industrial equipment. Oil-filled construction provides robust dielectric performance and extended operational life in harsh industrial environments.
Key Features
- 7.0 microfarad (uF) capacitance rating
- 400 volt DC (VDC) voltage rating
- Oil-filled dielectric for superior performance and thermal stability
- Heavy-duty construction designed for industrial applications
- Suitable for power supply filtering and energy storage in legacy systems
Technical Specifications
The S64036 features specifications typical of oil-filled industrial capacitors of its era. The 7.0uF rating at 400VDC allows operation in moderate- to high-voltage DC circuits. Oil-filled construction ensures stable capacitance across temperature variations and provides enhanced electrical properties compared to paper or film dielectrics used in some competing designs.
Typical Applications
- DC bus filtering in industrial power supplies and motor drives
- Energy storage in legacy UPS (uninterruptible power supply) systems
- Power conditioning in vintage industrial control equipment
- Maintenance and restoration of legacy electrical systems
- Military and aerospace equipment requiring MIL-SPEC replacements
Compatibility & Replacements
Compatible With
- Industrial DC power supplies rated 400VDC or less
