Overview
The K7X29KO mylar capacitor is a high-reliability polyester film capacitor with a capacitance value of 0.047µF and voltage rating of 400V. Non-polarized polyester film (Mylar) capacitors are dipped in a hard epoxy coating material to provide excellent protection against moisture. This bulk package of 100 units is ideal for electronics manufacturers, repair shops, and system integrators requiring consistent component supply for assembly and maintenance operations.
Key Features
- Capacitance: 0.047µF (47nF)
- Voltage Rating: 400V
- Dielectric Material: Polyester film (Mylar)
- Non-polarized: Can be installed in either direction
- Epoxy Coating: Moisture and environmental protection
- Bulk Quantity: 100 units per bag for high-volume applications
Technical Specifications
Mylar or Polyethylene terephthalate (PET) capacitors have low ESR and can operate at temperatures up to 125°C without much voltage derating. The epoxy dip coating provides durability in industrial environments with fluctuating humidity levels.
Typical Applications
Mylar capacitors are suitable for high frequency filtering, outdoor applications where moisture can be a problem, high voltage or current peaks in circuits, and coupling and de-coupling circuits. Common uses include:
- Power supply filtering and smoothing
- AC coupling and signal conditioning
- Timing and RC circuits
- Industrial control and automation equipment
- Commercial HVAC and motor control systems
- Audio and communication equipment
