DRM1-S 1W DC-DC Converters

CUI Inc DRM1-S 1W DC-DC Converters offer a 1W isolated output rating and an isolation voltage rating of 3000V_DC. These converters feature single and dual unregulated output and an industry-standard 7-pin SIP package. Additional features include a wide operating temperature range of -40°C to +100°C, typical voltage ratings of 5V_DC, 12V_DC, and 24V_DC, and a 100mVp-p ripple and noise rating. CUI Inc DRM1-S and 1W DC-DC Converters are suitable for consumer electronics, smart home appliances, and small-scale automation applications.
