The TW-DH-203 is a high-voltage arc ignition transformer manufactured by Jiangsu Tianwang Solar Technology Co., Ltd. It steps a DC 4.0V input up to an 8kV ±10% arc output at an 18kHz working frequency, inside a potted 18.8 × 18.1 × 8.9 mm package. It is the ignition core used in rechargeable arc lighters, Type-C rechargeable arc ignition , and other flameless ignition devices - including high-power units built to light cigars, charcoal, and wood.
What Is an Arc Lighter High Voltage Transformer?
An arc lighter high voltage transformer - also called an arc ignition transformer, booster coil, step-up transformer, or high voltage module - converts the low DC voltage of a battery into a high-frequency, high-voltage output. When that voltage is applied across two electrodes, it exceeds the breakdown voltage of the air gap between them, and a plasma arc forms. That arc is what ignites the material: no flame, no butane, no gas refill.
In an arc lighter, this transformer is the single component that decides how strong the arc is, how reliably the device starts, and whether it can light demanding materials instead of only cigarettes. The TW-DH-203 is designed for exactly that role: a potted module that a lighter or ignition-gun manufacturer can drop into an existing housing and battery platform.

All electrical parameters are measured under laboratory conditions of 22–28°C and 30–80% RH. Output voltage is verified with a multimeter and a 1:1000 attenuation probe; both inductances are measured with an inductance tester at 1kHz and 1.0V.
How the TW-DH-203 Produces an Ignition Arc
The working principle is electromagnetic induction. The primary coil is driven at 18kHz with a 60% duty cycle; according to the turns ratio between the two windings, the magnetic field generated by the primary current induces a far higher voltage in the secondary coil. The module raises the voltage from a DC 4.0V input to an 8kV ±10% output.
That output is applied across the two output electrodes. When the field strength exceeds the dielectric strength of the air between them, the gap breaks down and a plasma arc appears. Because the arc is electrical rather than combustive, it is not affected by airflow the way a flame is, and it introduces no fuel residue into the material being lit.
Applications: Rechargeable Arc Lighters, Type-C Arc Ignition Guns, and More
The TW-DH-203 is supplied as an OEM component for the products that generate the arc:
Rechargeable arc lighters - single-arc and multi-arc designs that use a lithium battery and a charging port instead of fuel.
Type-C rechargeable arc ignition guns - point-ignition tools with a longer reach, used for lighting in hard-to-reach places.
High-power ignition devices - configurations where the arc must light materials that resist ignition: cigars, charcoal, wood.
Flameless ignition equipment - any device that needs an electric arc instead of an open flame, including outdoor and wind-exposed use.
If your product integrates a rechargeable lighter or ignition-gun platform, the 203 module is the ignition stage of that design. See our full range on the arc lighter transformer page.
Designed to Ignite Cigars, Charcoal, and Wood
Ordinary lighters are limited by a soft flame and a small heat release, which is why many of them struggle with cigars, charcoal, or wood. The TW-DH-203 is built around a high-power arc output: the 8kV ±10% secondary output produces a concentrated, high-temperature arc instead of a flame, and that is what allows the finished device to light the materials users actually find difficult.
Three practical consequences follow from the design:
Flameless ignition. There is no flame to blow out, so performance stays consistent in wind and at different altitudes.
No fuel, no refilling. The device is powered by a rechargeable battery, so there is no butane to buy, store, or refill.
No fuel residue on the material. Because nothing is burned to create the arc, no gas or butane by-products are deposited on the cigar, charcoal, or wood surface.
Mechanical and Interface Design for OEM Assembly
The module measures 18.8 ±0.15 mm × 18.1 ±0.1 mm × 8.9 ±0.1 mm - compact enough for slim lighter bodies. The body is potted, with no stains, oil, rough edges, or distortion on the surface, no damage or adhesive on the lead wires, and no live parts exposed on the surface. Input and output terminations are customizable so the module can match your housing, PCB layout, and wiring route.
Quality Control and Test Conditions
Each parameter of the TW-DH-203 is defined by a measurable test method rather than a nominal claim:
| Test item | Method |
|---|---|
| Input voltage | Adjustable regulated power supply |
| Output voltage | Multimeter with 1:1000 attenuation probe |
| Primary / secondary inductance | Inductance tester, 1kHz, 1.0V |
| Appearance | Surface, wire, and live-part inspection per drawing |
| Environment | 22–28°C, 30–80% RH |
Products are packed in corrugated boxes for bulk shipment.
Customization and OEM/ODM Supply
Because the module sits inside another manufacturer's product, input and output terminations are customizable, and we produce to drawing rather than to a single fixed configuration. Tell us your battery platform, housing dimensions, required arc strength, and target end product, and our engineering team will confirm what can be built.
