WEET What Affects The Cost Of WMO Crossover Oil Copper Capacitor?

March 10, 2026

WMO Copper Foil Paper and Wax Capacitors are the top choice for audio enthusiasts, but is it expensive?

In fact, the price of the WEET WMO Crossover Oil Copper Capacitor 400V is affected by many factors.

1. Technical parameters and performance requirements (the biggest influence)

   Capacitance and voltage rating: the larger the capacitance and the higher the voltage, the more copper foil and PP film are used, and the higher the cost of the casing.

   Special performance: high temperature resistance, low loss, and long service life all require high-purity PP film and precision manufacturing processes, which can increase costs by more than 30%.

2. WMO Crossover Oil Copper Capacitor: Raw Material Costs

   Core materials: PP polypropylene film, a petrochemical product whose price fluctuates with oil prices; copper foil, directly affected by copper prices; insulating oil (mineral oil), with high premiums for high-end models.

3. WMO Crossover Oil Copper Capacitor: Certification and compliance costs

   Safety certifications: VDE, UL and others involve high testing costs.

   Environmental compliance: RoHS and other standards increase management costs. Non-compliant products cannot enter the market.
