TDN 3-1221WISM

The TDN 3-1221WISM from Tracopower is a TDN 3WISM series, 3W DC/DC converter. This fully regulated, high performance DC/DC converter comes in a compact cubical package of only 1.23cm³. Full load operation is reliable up to 70°C environment temperature. With 1600VDC I/O isolation voltage, external on/off and short current protection, it covers a wide range of application when space is limited. The input of converters is designed for a wide voltage range (4:1) and minimum load is not required. It features conducted noise (EN 55022 class A or B with external components), ESD (EN 61000-4-2, air ±8KV, contact ±6KV, pref A), radiated immunity (EN 61000-4-3, 10 V/m, pref A), fast transient / surge (with external input capacitor) (EN 61000-4-4, ±2KV, pref A and EN 61000-4-5, ±1KV pref A), conducted immunity (EN 61000-4-6, 10VRMS, pref A) and magnetic field immunity (EN 61000-4-8, 100A/m continuous, pref A, 1000 A/m 1sec, perf criteria A).
