Abstract
Newly developed small-size power relays are described and their test results on switching load durability are presented. They are half the case volume compared to plug-in low-profile ISO Microrelays. Test temperature for the relays was 120 °C keeping in mind engine room conditions. Operation voltage was 14 V. Contact resistance of the normally-open type kept stable values ranging from 3 to 4 mΩ in lamp load tests (11 A, 300k cycles) and in horn load tests (11 A, 150k cycles). Contact resistance in the transfer (change-over) type kept stable values ranging from 3 to 9 mΩ in windshield wiper motor load tests (8 A, INT operation, 600k cycles).
