Yamaichi Electronics has announced the TF junction box for thin film modules. The TF junction box for thin film modules by Yamaichi Electronics is the first thin film junction box that has kink protection with Hermetic Sealed technology. This is the first time this familiar technology has been used in a junction box.
/> The TÜV and UL listed junction box can optionally be delivered with or without diodes. In case of shadow, Hermetic Sealed design permits the overmolded diodes to discharge significantly more heat than a non-overmolded variant.

With the Hermetic Sealed technology, the junction box is not composed of individual falling parts. Instead, the cables and electronic of the box are insert-molded in a single highly efficient work step. This overmolding process gives the J-box its shape and ensures absolute freedom from leaks. This increases the lifetime and safety of the entire photovoltaic installation.

The simple mounting of the TF junction box on the solar panel with high-quality adhesive pads ensures cost-effective and safe production. The bands of the photovoltaic module are contacted through clamping terminals. No additional injection mass. Mounting is possible without tools. For automated production, the separately available mounting tool is recommended. The box and cover can be attached simultaneously with the clamping contacts and crimped.

The TF junction box, with a height of only 14 mm, is among the flattest boxes on the market and can be used even when space is tight.
