What feryster sp. z o.o. does

Feryster Sp. z o.o. is a Polish private limited-liability company (Sp. z o.o.) headquartered in Iłowa, Poland, specializing in the manufacture of inductive electronic components — including transformers, chokes, coils, ferrite and powder cores, bobbins, EMI filters, and related accessories — for power-electronics applications such as switched-mode power supplies (SMPS), LED drivers, industrial electronics, and CCFL backlighting. The company is family-owned by Barbara and Zdzisław Sobków and operates with approximately 14–15 named staff spanning production, engineering, finance, logistics, quality, IT, and sales. Feryster differentiates through proprietary design IP, including UL-certified FER-130 (Class B, 130°C) and FER-155 (Class F, 155°C) electrical insulation systems (UL file E481059), enlarged-creepage-distance bobbins that maximize ferrite-core power utilization, and NANOPERM-core current-compensated chokes for high-frequency EMI suppression. Certifications include ISO 9001:2015 (held since 2002) and the UL insulation-system file obtained in 2016.

The company operates a hybrid revenue model combining hardware sales (standard flyback transformers and stocked inductive components sold via its own e-shop at sklep.feryster.pl, Allegro marketplace, and the TME catalog distributor) with custom design and engineering services delivered through a sales-led, consultative RFQ process ([email protected], [email protected], [email protected]). It holds exclusive distribution rights for Micrometals Arnold Powder Cores across Eastern Europe (since October 2008) and distributes Power Integrations controllers and design-software libraries (PI Expert Suite), functioning as a specialty component and design-support supplier for OEMs and power-electronics designers in Poland, the Czech Republic, Slovakia, Ukraine, Belarus, Lithuania, Latvia, and Estonia. The go-to-market relies on a professional website with technical content, multi-language support (Polish, English, German), trade-show presence (Electronica, CWIEME, PCIM Europe, Automaticon, Amper, Coiltech, Evertiq Expo), and a small named sales and technical-consulting team. No public revenue, headcount growth, or external funding data is disclosed.
