When two or more power supplies are used side by side, position them with proper intervals to allow enough air ventilation. The temperature around each power supply should not exceed the temperature range shown in derating curve. ¡ Avoid placing the AC input line pattern layout underneath the unit.It will increase the line conducted noise. Make sure to leave an ample distance between the line pattern layout and the unit. Also avoid placing the DC output line pattern underneath the unit because it may increase the output noise. Lay out the pattern away from the unit. ¡ Avoid placing the signal line pattern layout underneath the unit because the power supply might become unstable. Lay out the pattern away from the unit. ## Stress to the pins ¡ Applying excessive stress to the input or output pins of the power module may damage internal connections. Avoid applying stress in excess of that shown in right figure. - ¡ Input/output pin are soldered to the PCB internally. Do not pull or bend a lead powerfully. - ¡ If it is expected that stress is applied to the input/output pin due to vibration or impact, reduce the stress to the pin by taking such measures as fixing the unit to the PCB by silicone rubber, etc. Less than Less than 19.6N(2kgf) 19.6N(2kgf) Less than 19.6N(2kgf) ## Soldering - ¡ Flow soldering: 260 C for up to 15 seconds. - ¡ Soldering iron (26W): 450 C for up to 5 seconds. ## **Derating** ## ¿ Derating curve for input voltage **==> picture [103 x 87] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>50<br>AC50V AC85V Vin<br>DC70V DC120V<br>(a)TUHS3<br>Load[%]<br>**----- End of picture text -----**<br> **==> picture [102 x 73] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>40<br>in AC50V AC85V V<br>DC70V DC120V<br>Load[%]<br>**----- End of picture text -----**<br> - (b)TUHS5,TUHS10,TUHS15,TUHS25 **TUHS-12** www.cosel.co.jp/en/ December 27, 2022 ## **TUHS-series** ## **Derating** - ¿ TUHS3F Ambient temperature derating curve (Reference value) **==> picture [220 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>80<br>60<br>40<br>20<br>Convection (0.2m/s),Forced air (2.0m/s)<br>0<br>85<br>-40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ]<br>Load factor[%]<br>**----- End of picture text -----**<br> - ¿ TUHS5F Ambient temperature derating curve at convection cooling (Reference value) **==> picture [220 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>80<br>75<br>60<br>40<br>Convection(0.2m/s)<br>1 TUHS5F05,TUHS5F12,TUHS5F15<br>20<br>2 TUHS5F24<br>0<br>75 85<br>-40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ]<br>Load factor[%]<br>**----- End of picture text -----**<br> - ¿ TUHS10F Ambient temperature derating curve at convection cooling (Reference value) **==> picture [220 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>80<br>60<br>40<br>Convection(0.2m/s)<br>1 TUHS10F05,TUHS10F15<br>20<br>2 TUHS10F12,TUHS10F24<br>0<br>55 85<br>-40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ]<br>Load factor[%]<br>**----- End of picture text -----**<br> - ¿ TUHS15F Ambient temperature derating curve at convection cooling (Reference value) **==> picture [220 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>1<br>80<br>2 3<br>60<br>40 Convection(0.2m/s)<br>1 TUHS15F12<br>20 2 TUHS15F15<br>3 TUHS15F24<br>0<br>45 85<br>-40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ]<br>Load factor[%]<br>**----- End of picture text -----**<br> - ¿ TUHS5F Ambient temperature derating curve at forced air (Reference value) **==> picture [220 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>80<br>60<br>40<br>20 Forced air(2.0m/s)<br>0<br>85<br>-40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ]<br>Load factor[%]<br>**----- End of picture text -----**<br> - ¿ TUHS10F Ambient temperature derating curve at forced air (Reference value) **==> picture [220 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>80<br>60<br>40<br>Forced air(2.0m/s)<br>1 TUHS10F05,TUHS10F15<br>20<br>2 TUHS10F12,TUHS10F24<br>0<br>75 85<br>-40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ]<br>Load factor[%]<br>**----- End of picture text -----**<br> - ¿ TUHS15F Ambient temperature derating curve at forced air (Reference value) **==> picture [221 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100<br>80<br>60<br>40<br>Forced air(2.0m/s)<br>1 TUHS15F12,TUHS15F15<br>20<br>2 TUHS15F24<br>0<br>75 85<br>-40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ]<br>Load factor[%]<br>**----- End of picture text -----**<br> **TUHS-13** www.cosel.co.jp/en/ December 27, 2022 ## **TUHS-series** ## **Derating** > ¿ TUHS25F Ambient temperature derating curve at convection cooling (Reference value) > ¿ TUHS25F Ambient temperature derating curve at forced air (Reference value) **==> picture [473 x 117] intentionally omitted <==** **----- Start of picture text -----**<br> 100 CT TT TTT RAR TT 100 [TT TT TT TT TT Tiel |<br>3<br>80 —i ttt} | PANN ET 80 pf | | tt ft tt tT ONT<br>2 75<br>—f | ft | | tt INA LE ee ee ee ee ee eo<br>1<br>60 —i | tt | tt | ANAA ET 60 pf | | tt ft tt Pt AT<br>i NN i a<br>40 Lf Convection(0.2m/s) ee 40 ee<br>|_| 1 TUHS25F05 Vt IN | Forced air(2.0m/s) Peeee ee e<br>20 2 TUHS25F12,TUHS25F24 20 1 TUHS25F05,TUHS25F15<br>3 TUHS25F15 2 TUHS25F12,TUHS25F24<br>0 0<br>xDD 85 |__| LezzeZeEZALIZILEZELMMAA 75 85 |__|<br>-40 -20 0 20 40 60 80 100 -40 -20 0 20 40 60 80 100<br>Ambient temperature[ C ] Ambient temperature[ C ]<br>Load factor[%] Load factor[%]<br>**----- End of picture text -----**<br> ¡ Derating curve is shown below.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
