Lead Content Greatly Reduced!｜Earth-Friendly Resistors are Currently under Development
2025.01.22
Lead-free Resistors Compliant with RoHS threshold without exemptions
RK73-FT Series
KOA has developed lead-free resistors with less than 1000ppm of lead in each part of electrodes, resistors and glass, which are currently exempted from EU-RoHS Directive, in order to realize an environmentally friendly and sustainable society.
Sample support has been started.
We plan to start mass production in January 2026 and plan to offer a wide lineup of products from general-purpose types (RK73-FT series) to highly functional products such as pulse/surge resistant (SG73P/S-FT series) and wide terminal (WK73-FT series) resistors.
(Applications)
Car electronics, industrial equipment, power supply, home appliances, telecommunications, measuring equipment etc.
