1. General Information & Product Series:

️· Product Series: CRE1S Series
️· Type: Isolated DC-DC Converters (Single Output)
️· Power: 1 Watt
️· Application: Presumably for electronics/power circuits requiring efficient DC-DC conversion.
️· Website: [http://www.murata-ps.com/requirements/](http://www.murata-ps.com/requirements/) (for operating requirements and Life/Safety/Critical application policies)

2. Models and Pin Configurations:

️· Variations: The series includes several models with different suffixes indicating variations (e.g., DC, SC, 3C, MEC, MC). The suffix seems to denote packaging/mechanical options.
- DC: 8-pin DIP package.
■ Pin 1: -VIN
■ Pin 3: +VIN
■ Pin 7: -VOUT
■ Pin 8: +VOUT
- SC & 3C: 4-pin SIP package.
■ Pin 1: -VIN
■ Pin 2: +VIN
■ Pin 1: -VOUT
■ Pin 4: +VOUT
️· Marking: Includes date codes (WW) and product codes (XYY).

3. Electrical Specifications (Implied - not directly listed but present):

️· Isolation: These are *isolated* DC-DC converters, meaning input and output are electrically separated.
️· The datasheet does *not* include detailed electrical specifications (input voltage range, output voltage, efficiency, regulation, etc.) These are likely found in more detailed documentation.

4. Packaging & Mechanical Details:

️· Package Dimensions: Detailed drawings and dimensions are included for:
- DC Package (8-pin DIP)
- SC Package (4-pin SIP)
- 3C Package (4-pin SIP)
️· Pin Pitch: 2.54mm (0.100 inch) with tolerances.
️· Weight: Specified for 3C (1.09g), SC (1.30g), and DC (1.38g).
️· Reel Packaging Details: (Information not fully clear - mentions reel packaging for specific models.)

5. Regulatory and Disclaimer:

️· Intellectual Property: Murata Power Solutions makes no representations regarding patent infringement.
️· Specifications Subject to Change: Datasheet information can be updated without notice.
️· Copyright: © 2018 Murata Power Solutions, Inc.

Key Things Missing:

️· Detailed Electrical Specifications: This is the biggest omission. No input/output voltage ranges, output current, efficiency numbers, regulation, or other critical electrical performance data are provided. You've essentially got packaging, mechanical details, and a general overview.
️· Application Notes: No guidance on how to use the converter in a circuit.
