DC/DC converter TracoPower TEM 3-0522N — TEM 3N, 3 W, 12 V output, 125 mA, DIL-24

TracoPower TEM 3-0522N is a compact DC/DC converter from the TEM 3N series that provides 3 W of isolated regulated power in a DIL-24 through-hole package. It delivers a 12 V output at up to 125 mA and is intended for board-level power isolation and low-power voltage conversion. The device is suited to industrial and embedded designs where a small footprint, galvanic isolation and stable low-current supply rails are required.

Advantages

The converter offers galvanic isolation between input and output to improve safety and reduce noise coupling. Its regulated 12 V output ensures stable voltage under varying load within the rated limits. The DIL-24 through-hole package enables straightforward PCB mounting and mechanical robustness for assembly and field service. The unit’s low power rating and compact size make it appropriate for auxiliary supplies and signal conditioning tasks where space and thermal budget are limited.

Suitable for

• Isolated auxiliary power rails for industrial control boards
• Powering low-current sensors, instrumentation, and signal conditioning circuits
• Embedded systems requiring small, through-hole isolated converters
• Test fixtures and measurement equipment needing a separated supply

Key specifications

• Output power: 3 W
• Output voltage: 12 V (regulated)
• Maximum output current: 125 mA
• Package type: DIL-24 through-hole
• Function: isolated DC/DC voltage conversion for board-level applications

How to use

Mount the converter on the PCB using the DIL-24 footprint and follow the manufacturer’s recommended spacing for creepage and clearance to preserve isolation. Provide the specified input voltage and observe polarity. Use appropriate input and output decoupling capacitors as recommended in the device documentation to ensure stability and low output ripple. Verify that the connected load does not exceed the 3 W power limit and the maximum output current of 125 mA to avoid thermal or regulation issues.

Usage recommendations

Place the module in a location with adequate airflow and away from heat sources. Ensure isolation requirements are met by maintaining recommended creepage and clearance distances on the PCB. For reliable long-term operation, avoid continuous operation near the maximum rated power and verify temperature rise under expected load conditions during system validation.
