TEL 15

TEL 15 series is a kind of DC/DC converters which has wide input range of 2:1. State of the art SMD-technology guarantees a product with very high reliabilityand good cost /performance ratio. High efficiency allows an operating temperature range of -25°C to +71°C without derating. This product serie provides an economical solution for many cost critical applications in industrial and consumer electronics.It has eight unique features: The first one is high efficiency which is up to 86%. The second one is operating Temp. range is 25°C to +71°C. The third one is indefinite short-Circuit protection. The forth one is I/O-Isolation 1500 VDC. The fifth one is industry standard pinout. The sixth one is cost optimized design. The seventh one is lead free design, RoHS compliant. The eighth one is 3 year product warranty.
