Series B & SB

Product catalog summary

Product Overview: The Series B & SB are unregulated DC-DC converters offered by Pico Electronics, featuring an ultra-miniature encapsulated package with a footprint of 1.12” x 0.7” and a low profile of 0.3”. These converters are available in over 180 models with single and dual outputs, capable of operating within a temperature range of -25°C to +70°C without the need for derating, heat sinks, or active cooling.

Features: The converters provide up to 2.5W output at +70°C ambient temperature, with encapsulated semiconductors for maximum reliability. They offer input models ranging from 5V to 48V and output models up to 48V, with 500VDC isolation at 100MΩ. The products are available in both through-hole (B) and surface mount (SB) configurations, with options for expanded operating temperatures, MIL-STD-883 screening, and RoHS compliance.

Specifications: The input voltage range varies by model, with specific ranges for 5V, 12V, 15V, 24V, 28V, and 48V input models. The converters feature a line regulation where output voltage is directly proportional to input voltage. Environmental specifications include an operating temperature range of -25°C to +70°C and a storage temperature range of -55°C to +125°C. The converters are designed for free air convection cooling.

Protections & Features: The converters are designed to meet various MIL-STD-202 standards for vibration, shock, humidity, and altitude. They also include short circuit protection.

Options Available: Pico Electronics offers options such as stabilization bake, temperature cycling, burn-in, and expanded ambient operating temperature ranges. RoHS compliance is also available.

Mechanical Drawings: Detailed mechanical drawings are provided for both Series B (through-hole) and Series SB (surface mount) configurations, including dimensions and recommended land pattern dimensions.

Warranty: Pico Electronics provides a one-year warranty against defects in material and workmanship, with limitations on liability for consequential damages and specific usage environments.
