Преобразователи постоянного тока в постоянный с изоляцией TEN 3-1221N

Isolated Through Hole DC/DC Converter , ITE, 2:1, 3 Вт, 2 Выхода, 5 В, 250 мА

The TEN 3-1221N from Tracopower is a 3W dual output DC to DC converter in 24 pin DIP package. It is a drop in replacement of the prevalent TEN 3 series DC to DC converter. The up-to date design enables a cost reduction without any compromise to reliability and function. This DC to DC converter has wide 2:1 input voltage range and input filter to meet EN 55022, class A and FCC, level A without external components. Increased EMC immunity and extended operating temperature range make this converter as an ideal solution for cost critical but demanding applications. It is a drop in replacement for common 3W converters in DIP24 package with the standard pinning. The converter has continuous, automatic recovery short circuit protection and no minimum load is required. The TEN 3-1221N has EN 61000-4-2, air ±8KV, contact ±6KV (criteria A) ESD protection and non conducting FR4 case with UL 94V-0 rated epoxy potting and gold plated copper alloy pins.
