OKX T/3-W5 Series

Adjustable 3-Amp SIP Non-Isolated DC/DC Converters

Output Voltage Adustment

The output voltage may be adjusted over a limited range by connecting an

OKX-T/3-W5

R TRIM ( ) = ____________

external trim resistor (Rtrim) between the Trim pin and Ground.The Rtrim resistor

is recommended to have a ±0.5% accuracy (or better) with low temperature

coef?cient, ±100 ppm/°C or better. Mount the resistor close to the converter with

very short leads or use a surface mount trim resistor.

In the tables below, the calculated resistance is given. Do not exceed the

speci?ed limits of the output voltage or the converter’s maximum power rating

when applying these resistors. Also, avoid high noise at the Trim input. However,

to prevent instability, you should never connect any capacitors to Trim.

Soldering Guidelines

Murata Power Solutions recommends the speci?cations below when installing these

converters. These speci?cations vary depending on the solder type. Exceeding these

speci?cations may cause damage to the product. Your production environment may dif-

fer; therefore please thoroughly review these guidelines with your process engineers.

Product Label

Because of the small size of these products, the product label contains a

character-reduced code to indicate the model number and manufacturing

date code. Not all items on the label are always used. Please note that the label

differs from the product photograph on page 1. Here is the layout of the label:

The manufacturing date code is four characters:

First character – Last digit of manufacturing year, example 200 9

Second character – Month code (1 through 9 and O through D)

Third character – Day code (1 through 9 = 1 to 9, 10 = O and

11 through 31 = A through Z)
