MKP Metal Film Audio Capacitor — 100V, 1.5µF / 2.2µF / 3.3µF, HIFI Coupling & Crossover
High-quality MKP (Metallised Polypropylene) film capacitors rated at 100V DC, available in 1.5µF, 2.2µF, and 3.3µF values for high-fidelity audio applications. MKP capacitors offer significantly lower ESR, lower dielectric absorption, and lower distortion than standard electrolytic capacitors, making them the preferred choice for audio signal coupling, loudspeaker crossover networks, and frequency divider circuits in HIFI and audiophile audio equipment.

Typical Applications
- Loudspeaker Crossover: Series and shunt capacitors in 2-way and 3-way passive loudspeaker crossover networks for tweeter high-pass and midrange bandpass filters
- Audio Signal Coupling: DC-blocking coupling capacitor in the signal path of preamplifiers, tone controls, and audio amplifier input/output stages
- Frequency Divider: Capacitor in active and passive frequency divider circuits for subwoofer crossover and high-pass filter applications
- Amplifier Bypass: Bypass capacitor across electrolytic power supply capacitors in audio amplifiers to improve high-frequency performance
- HIFI Upgrade: Replace standard electrolytic coupling capacitors in vintage amplifiers and preamplifiers with MKP film capacitors for improved audio transparency
FAQ
Q: Can I use MKP capacitors in AC circuits?
A: MKP capacitors are non-polarised and can be used in AC signal circuits. For mains AC applications (X2 capacitors), use specifically rated X2 MKP capacitors. These 100V DC rated capacitors are for audio signal and low-voltage AC applications only.
Q: What value should I use for a tweeter crossover at 3kHz?
A: For a first-order (6dB/octave) high-pass crossover at 3kHz with an 8Ω tweeter: C = 1 / (2π × f × R) = 1 / (2π × 3000 × 8) ≈ 6.6µF. Use two 3.3µF MKP capacitors in parallel for this value.
