Ethertronics an AVX Group Company

What Ethertronics an AVX Group Company does

Ethertronics operates as part of the AVX Group under KYOCERA AVX Components Corporation, a wholly-owned subsidiary of Kyocera Corporation following Kyocera's 2019 acquisition of AVX Corporation. The company manufactures advanced electronic passive and interconnect components, with a portfolio spanning antennas, capacitors (ceramic, tantalum, aluminum electrolytic, polymer, film, supercapacitors, and RF/microwave), connectors, circuit protection devices (diodes, fuses, multilayer varistors, thermistors), crystal devices, RF/microwave filters, inductors, resistive products, SAW devices, sensing and control solutions, and thermal management products. Engineering investments include proprietary thin-film processes, ultra-broadband component technology, radiation-tolerant capacitors, and differential clock crystal oscillators with industry-leading 30 fs phase jitter. The company also offers design enablement tools, including the SpiCAT simulation platform and a web-based Antenna Integration Tool (AIS).

KYOCERA AVX serves seven vertical markets — automotive, aerospace & defense, medical, 5G/IoT, industrial, consumer electronics, and communications infrastructure — with automotive and 5G/IoT identified as primary segments and aerospace/defense supported through DLA/MIL-SPEC certified product lines. Revenue is generated through hardware sales via an authorized global distributor network, regional sales representatives, and direct online ordering for sample and small-quantity purchases. Manufacturing and R&D operations span several dozen facilities across more than 15 countries, supporting a global customer base with localized technical sales, application engineering, and design-tool access. The business operates as a captive subsidiary within Kyocera Corporation, with no independent public shareholders or venture funding, and benefits from the parent conglomerate's balance sheet and global operational infrastructure.
