Description
Custom 1.5kW Low Loss PQ5033 High Frequency Planar Transformer for EV Charger OBC
This 1.5 kW PQ5033 planar transformer is purpose-built for EV on-board chargers (OBC), DC-DC converters and LLC resonant power stages. Instead of conventional round magnet wire, the windings are realized as etched copper layers inside a multilayer PCB, terminated with heavy copper clip terminals for low contact resistance and high current capability. The result is a transformer with excellent turn-to-turn consistency, very low leakage inductance, low AC loss at high switching frequency and a low-profile footprint that fits the tight height budget of automotive power modules.
Key Advantages
  • Planar PCB Winding — Repeatable Electrical Performance: Winding geometry is fixed by the PCB artwork, so leakage inductance and turns ratio are virtually identical unit to unit — critical for LLC resonant tank tuning in mass production.
  • Low Loss at High Frequency: Wide flat conductors minimize skin and proximity effect, keeping AC resistance low in the 100 kHz–500 kHz range where round-wire designs start to heat up.
  • Dual PQ5033 Core Set — High Power Density: Paired ferrite cores share the flux and thermal load, supporting continuous 1.5 kW throughput in a compact package.
  • Copper Clip Terminals: Heavy-gauge tinned copper clips carry high primary/secondary current with minimal terminal loss, and provide a robust mechanical joint under automotive vibration.
  • Superior Thermal Behaviour: The large flat surface area of the planar structure conducts heat directly into the PCB and heatsink, giving a lower hot-spot temperature than a wound bobbin of the same rating.
  • UL Recognized Materials: Constructed with UL-listed insulation and core materials, UL File No. E332338.
  • Fully Custom Engineered: Turns ratio, layer stack-up, magnetizing and leakage inductance, terminal layout and core gap all designed to your converter topology.

Custom Design Process
  1. Share your requirement — topology, input/output voltage, power, switching frequency, height limit.
  2. Design proposal — our magnetics engineers return core selection, layer stack-up, turns ratio and expected loss/temperature rise.
  3. Sample build & test — prototype with full test report (Lm, Lk, turns ratio, DCR, Hi-Pot).
  4. Design freeze & mass production — controlled process, batch traceability, 100% electrical testing.
Packaging & Delivery
  • Inner packing: anti-static bag / partition tray
  • Outer packing: 5-layer export carton, wooden pallet on request
  • Sample lead time: 10 – 15 working days (custom design)
  • Mass production: 20 – 30 working days after design freeze
  • Trade terms: EXW / FOB / CIF
FAQ
Q1: Can you design the planar transformer to our OBC schematic?
Yes. Send us the topology, input/output specification, switching frequency and mechanical height limit, and we will return a full design proposal with calculated loss and temperature rise.
Q2: Is the PCB winding included, or do we integrate it into our main board?
Both options are supported. We can supply the transformer as a complete assembly with its own winding PCB and copper clip terminals, or design the winding layers for integration into your motherboard.
Q3: What leakage inductance tolerance can you hold?
Because the winding geometry is defined by the PCB, leakage inductance spread is far tighter than a hand-wound part. The exact tolerance is confirmed on the approved sample and controlled in production.
Q4: What test reports do you provide?
Magnetizing inductance, leakage inductance, turns ratio, DCR, Hi-Pot and temperature-rise data can be supplied with each shipment on request.
Send us your OBC specification today — our planar magnetics engineers will reply with a custom design proposal and quotation within 24 hours.
