You know why do silver and gold-plated copper leads matter in an audio crossover capacitor? In an Audio Crossover Capacitor, lead materials are important for electrical conductivity and connection reliability. Silver-plated and gold-plated copper leads each offer different advantages for audio applications.

1. Why Do Capacitor Lead Materials Matter?

Capacitor leads connect the component to the circuit. Their material affects conductivity, solderability, and resistance to oxidation, all of which contribute to reliable electrical connections.

2. Silver-Plated Copper Leads: Conductivity and Performance

Silver offers excellent electrical conductivity. Combined with a copper core, silver-plated leads provide good conductivity and solderability, making them a suitable choice for audio capacitors.

3. Gold-Plated Copper Leads: Corrosion Resistance and Reliability

Gold is highly resistant to oxidation and corrosion. Gold-plated copper leads help maintain a stable contact surface and provide reliable connections over time.

4. WEET WMT Series: Designed for Audio Applications

The WEET WMT Series Hi-Fi Film Capacitor offers silver-plated and gold-plated copper lead options for different audio application requirements.

• Capacitance: 0.1 μF–100 μF

What Makes the WEET WMT Hi-Fi Film Capacitor Different? Let WEET tells you.

A Hi-Fi Film Capacitor is an important component in audio circuits, where low signal loss and stable electrical performance are essential. 

The WEET WMT series is designed for high-quality audio applications, combining metallized polypropylene film technology with carefully designed leads and low-loss characteristics.

• Low-Loss Performance for Audio Applications

  The WEET WMT features a very low dissipation factor, low equivalent series resistance (ESR), and low inductance. Its dissipation factor is specified at ≤0.0010 at 1 kHz, helping minimize energy loss during operation. The series also features a quick transient design and excellent handling of high-current audio pulses.

• Silver and Gold-Plated Copper Leads

  One distinctive feature of the WMT series is its silver- and gold-plated tinned copper wire lead options. These leads offer good solderability and reliable electrical connections, making the capacitor suitable for audio equipment assembly and long-term use.

• Flexible Specifications for Different Audio Circuits

  The WEET WMT series offers capacitance values from 0.1 μF to 100 μF, rated voltages from 50 VDC to 630 VDC, and capacitance tolerances of ±2%, ±3%, and ±5%, depending on the specification. This range provides flexibility for different circuit designs, including speaker crossovers, coupling, decoupling, and filtering applications.

WEE Technolgy Company Limited Published On Oct 23, 2026

WEET WMT Audio grade MKP capacitors are popular among audiophiles for speaker crossovers and other audio applications. But what affects the audio grade MKP capacitors price? WEET explains seven key factors below.

7 Factors Affecting WMT Audio Grade MKP Capacitors Price

1. Capacitance

Larger capacitance values generally require more materials, resulting in higher costs. For example, 10µF capacitors are usually more expensive than 1µF capacitors with the same voltage rating.

2. Voltage Rating

Higher voltage ratings generally require stronger insulation performance, which may increase production costs.

3. Material Quality

The quality of polypropylene film, electrodes, and leads affects cost. 

WEET WMT Audio Grade MKP Capacitors feature gold-plated copper leads, offering a distinctive material choice for audio applications.

4. Capacitance Tolerance

Tighter tolerances, such as ±1%, generally require more precise manufacturing and quality control than ±5%, potentially increasing the price.

5. Electrical Performance

Parameters such as low ESR, low DF, and low inductance can affect product cost. Buyers should compare specifications when evaluating audio capacitors.

6. Manufacturing Process

Film winding, lead welding, encapsulation, and electrical testing all contribute to production costs. Consistent quality control is essential for reliable performance.

7. Order Quantity

Larger orders may reduce unit prices, while small batches and customized specifications may involve additional costs. WEET supports B2B inquiries for audio capacitors and OEM/ODM requirements.

Conclusion

WMT audio grade MKP capacitors price depends on specifications, materials, performance, and order quantity. Contact WEET to discuss WMT capacitor specifications, request samples, and obtain a quotation for your project.

Our customer from Malaysia purchased WEET WMG Aluminum Foil and Film Capacitor for coupling function in guitar amplifiers.

2. Product Testing

• WMG 0.022uF 630V ±5% OD*L8*24mm Axial RoHS

• WMG 0.1uF 630V ±5% OD*L12*30.5mm Axial RoHS

3. Customer Feedback

"Very clear/detailed, a bit warm, but not as woolier/vintage sounding as polyester, as expected.

The less hi fi sound is preferred for guitar amps, usually.

But this is to be expected, and your caps perform quite well against what we currently use.

Perhaps, with more burn in, the performance will shine better.

I will also test your other caps."

--Nik from Malaysia

4. Conclusion

WEET WMG Aluminum Foil and Film Capacitors are constructed using separate layers of premium foil and polypropylene films, rather than the vapor deposited metallized film used by most other manufacturers.

Our customer from Germany recently purchased WEET WMH Audio Capacitors to replace the original capacitors in the speaker crossover of the Claro 6.2 by Sonor Audio.

2. Product Testing

Product Testing:

• 10.0uF 100V +/-3% 28x85mm Axial RoHS

• 4.7uF 100V +/-3% 21x75mm Axial RoHS

• 2.2uF 100V +/-3% 17x58mm Axial RoHS

3. Customer Feedback

"So (once more!) it was a good thing to replace all the caps with your WMHs, but they need a run in time of about a week. That is an absolute must!

By the way we also measured the usual specs of the Caps, ESR, Dissipation Factor, tangent delta, Q factor ….

All values of the WMHs were clearly better than in the Caps of Sonor Audio.

So there is no doubt that your caps are a lot better regarding measurements and sound quality as well.

We only can recommend speaker owners to change to your capacitors before any considerations of new speakers!"

--Hubert From Germany
