Why Choose TDK Film Capacitors?
TDK film capacitors are passive electronic components that use thin plastic films—typically polypropylene (PP) or polyester (PET)—as the dielectric material, metalized to form electrodes. These advanced capacitors are:
- Non-polarized and self-healing for long-term reliability
- Low loss and high insulation resistance for efficient operation
- Stable across wide temperature and frequency ranges
- ROHS compliant for environmental responsibility
Engineers rely on TDK film capacitors for their low ESR, high current capability, and consistent performance in both standard and harsh environments.
Key Features
- High stability and reliability
- Excellent self-healing properties
- Low dielectric losses
- Wide range of capacitance and voltage options
- Compact, space-saving designs
- AEC-Q200 qualified options for automotive and industrial applications
- Temperature stable and long lifetime, even in high frequency circuits
Film Capacitors vs. Electrolytic Capacitors
Film capacitors and electrolytic capacitors are both widely used in power electronics, but each capacitor type has distinct advantages.
Film capacitors offer lower ESR, higher ripple current capability, longer operational life, and self-healing properties, making them ideal for high-frequency, high-reliability, and demanding industrial applications.
Electrolytic capacitors provide higher capacitance in a compact size and are often chosen for bulk energy storage where cost is a primary concern.
For applications requiring superior stability, longevity, and high current handling—such as DC link circuits, frequency converters, inverters, and power supplies—TDK film capacitors are the preferred choice.
