General Description
The TRACO POWER TMH series is a range of 2W DC/DC converters in
a small SIP Package featuring an I/O-isolation of 1000VDC. An
excellent efficiency allows an operating temperature range of –40°C
to +85°C.These converters offer an economical solution for many
applications where a voltage has to be isolated i.e for noise
reduction, ground loop elimination, digital interfaces or for board
level power distribution with isolated voltages.

Class A Limits
Recommended PCB Layout with Input Filter
To: comply with EN55022 CLASS A following components are
needed:
Model Component ValueTMH 05xx C1 3.3μF/25V 1206 MLCC
TMH 12xx, TMH 24xx C1 1μF/50V 1206 MLCC
Input Source ImpedanceThe power module should be connected to a
low ac-impedance input source. Highly inductive source impedances
can affect the stability of the power module. In applications where
power is supplied over long lines and output loading is high, it
may be necessary to use a capacitor at the input to ensure
startup.Capacitor mounted close to the power module helps ensure
stability of the unit, it is recommended to use a good quality low
Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor
of a 2.2μF for the 5V input devices, a 1.0μF for the 12V input
devices and a 0.47μF for the 24V devices.

Safety and Installation Instruction
Fusing ConsiderationCaution: This power module is not internally
fused. An input line fuse must always be used.This encapsulated
power module can be used in a wide variety of applications, ranging
from simple stand-alone operation to an integrated part of
sophisticated power architecture. To maximum flexibility, internal
fusing is not included; however, to achieve maximum safety and
system protection, always use an input line fuse. The safety
agencies require a normal-blow fuse in 5Vin with maximum rating of
1000mA, in 12Vin with maximum rating of 500mA and in 24Vin with
maximum rating of 200mA. Based on the information provided in this
data sheet on Inrush energy and maximum dc input current; the same
type of fuse with lower rating can be used. Refer to the fuse
manufacturer’s data for further information.
