COO (Country of Origin):: TW

RECOM DC-DC Switching Regulator, 1 Output, 25mA Input Current - R-78HB Series - R-78HB12-0.5/W

Give your DC-powered devices exactly what they need with this switching regulator from RECOM. When an input voltage range between 17 and 72V DC enters the system, the unit takes it in hand and steps it down to a safer level of 12V DC. Thanks to an efficiency rating of 94%, you can rest assured that little energy is lost during this conversion process. This means you'll have minimal heat waste on your hands, so you won't need a heat sink on your board, freeing up space for other components.

• Pin-out compatible with LM78XX linear regulators for use with legacy devices

• Light weight of 4g for minimal strain on your board

• Ambient operating temperature range between -40°C and +85°C to withstand demanding settings

• Mean time between failures of 7,395,000h for reliable long-term operation

• Built-in short-circuit protection helps prevent damage from harmful current

Applications

• Transport industry

• Conveyor systems

• Automotive engineering

• Musical instruments

How clear are the electrical signals from this regulator?

This regulator has a maximum ripple and noise of 60mVp-p, so electrical disturbance and you'll get the signal clearly.
