Contact sticking resistance TEST CONDITION The purpose of this test was to confirm contact stick- ing resistance and contact stability against coil rip- ples. Tested Sample: NR-SD-24V, 10 pcs. Test method: Following coil ripples were applied. Test period: 500 hours TEST RESULT No occurance of sticking was observed. Contact resistance: Fig. 1 NR-SD-24V: 29 m Ω to 30.4 mΩ In actual application, above coil ripples should be avoided and use of a capacitor in the circuit is recom- mended to keep the ripple factor below 5%. 8.
