Description

OVERVIEW

PIT-3UEW-180 is a high-performance ultra-fine litz wire constructed with 0.04mm polyurethane-insulated copper strands and wrapped with polyimide (PI) film. With a total of 28,750 individual strands, it is designed for high-frequency, high-density, and high-temperature applications up to 180°C. The combination of ultra-fine conductors and PI tape insulation ensures excellent electrical performance, thermal stability, and mechanical reliability in demanding environments.

FEATURES

  • Enables ultra-low AC resistance at high frequencies
  • Withstands high temperatures up to 180°C
  • Provides strong dielectric insulation with polyimide film
  • Supports high current density in compact designs
  • Reduces proximity and skin effect losses
  • Ensures stable performance in continuous operation
  • Improves winding flexibility despite high strand count
  • Enhances durability under thermal and electrical stress

APPLICATION

  • High-frequency transformers
  • Wireless charging coils
  • EV power electronics
  • Inverters and power supplies
  • Medical and precision electronic equipment
  • Inductive heating systems
  • High-density motor windings
  • Aerospace and industrial control systems

FAQ

Q1: Can this wire be used in high-frequency high-voltage systems at the same time?

A1: Yes, the structure is optimized for both high-frequency performance and high-voltage insulation, making it suitable for advanced power electronics.

Q2: What insulation film materials are available?

A2: PET, PEN, and PI films are available, covering temperature classes from Class A (105°C) up to Class C (220°C+).

Q3: What overlap ratios are available?

A3: Standard overlap ratios are 50% and 67%, depending on the required insulation level and dielectric performance.

Q4: What information is required for a quotation?

A4: To provide an accurate quotation, please share the wire dimensions, insulation type, thermal class, required quantity, packaging requirements, and destination country.

Q5: If the MOQ is not met, can it still be produced?

A5: If the order quantity does not meet the MOQ requirement, we can also produce it for you, but the price will be higher than the MOQ price. Generally, it is calculated based on 3-5 times the MOQ unit price multiplied by the order quantity that you need, and plus a startup/module fee of 1,500 RMB. (If the total price of samples is higher than the MOQ price, then we will follow the total price of MOQ)
