AUDIO CAPACITORS FOR CROSSOVER NETWORKS & AMPLIFIERS | KINGTRONICS
Selecting the right polypropylene film capacitors or high-end foil structures is critical for minimizing signal degradation and delivering crystal-clear sonic performance. The Kingtronics premium Audio Capacitors lineup is engineered specifically for speaker crossover networks, power amplifiers, tweeters, and professional studio equipment demanding high-fidelity sound reproduction.
Optimized Audio Component Selection
Efficient crossover capacitor selection and amplifier capacitor selection require matching meticulous materials to your precise acoustic circuit design. Explore our advanced axial film series below to find the perfect fit for your high-end audio design needs:
| Series | Dielectric / Material Structure | Acoustic Character & Target Applications | Product Page Link | Technical Datasheet |
|---|---|---|---|---|
| FKT-XA | Precision Metallized Polypropylene | High precision capacitance, ultra-low ESR, and minimal inductance. Ideal for accurate signal transmission in crossover networks. | View FKT-XA | |
| FKT-XB | Elite Metallized Polypropylene | Features enhanced audio clarity, extremely low dielectric absorption, and exceptional stability under high-current audio pulse networks. | View FKT-XB | |
| FKT-XC | Ultra Metallized Polypropylene | Delivers an ultra-low dissipation factor, superior transient response, and outstanding signal stability for professional amplifier designs. | View FKT-XC | |
| FKT-XD | Platinum Aluminum Foil & Film | Pure foil-wound structure developed exclusively for premium Hi-Fi speaker systems, tweeters, and mid-range drivers to unlock complex acoustic details. | View FKT-XD | |
| FKT-XE | Studio Aluminum Foil & Film | Optimized for studio-grade mixing consoles and precision gear, offering stable high-frequency performance and low distortion. | View FKT-XE | |
| FKT-XF | Aurum Copper Tube & Film | Premium structure utilizing a pure copper tube outer shell with laser-etched markings. Delivers rich, organic warmth and authentic soundscapes. | View FKT-XF |
Advanced Sound Engineering and Acoustic Integrity
Why are polypropylene film capacitors widely used in audio circuits? Unlike standard industrial film capacitors, the Kingtronics Audio Series targets microphonic suppression and thermal phase drifts. By selecting our axial leaded configurations with low ESR capabilities, engineers can eliminate phase coloration across delicate mid-range and high frequencies, maintaining pure signal integrity throughout the entire soundstage.

About
Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
