CAUTION FOR PROPER USE OF PMLCAP
Ⓡ
Upon using PMLCAP
Ⓡ
, please pay attention to the points listed below.
Catalog may be subject to change without notice.
1. APPLIDE VOLTAGE
1) Rated voltage
As for applied voltage to capacitors, sum of DC voltage and peak AC voltage should not exceed their own DC rated
voltage.
2) Voltage derating
Within category temperature range, capacitors can be used without voltage derating.
3) Use in high frequency
Using capacitors at high frequency will be shortened its life due to the generation of heat. Please consult us in this
case.
4) Use in special wave-form
If you want to use capacitors with a special wave-form other than a sine wave, please inquire to us for details after
identifying the wave-form with which the capacitor is required to be used, because the effective value varies with
wave-form.
2.GUARANTEE OF CAPACITANCE TOLERANCE
PMLCAP
Ⓡ
characteristics may fluctuate by surroundings.Even if left in natural condition, capacitance may fluctuate by humidity.By
considering it, the product shall be shipped with special care at factory. But the guarantee of capacitance tolerance shall be
applied once before opening the humidity proof bag. It shall not be applied when individual agreement is exchanged.
3. PERMISSIBLE CURRENT
1) Permissible current for frequency
Please contact us in advance.
2) Permissible peak current (pulse current)
If you want to use capacitors with a special wave-form other than a sine wave, please inquire to us for details after
identifying the wave-form with which the capacitor is required to be used, because the effective value varies with
wave-form.
4. SELF HEAT RISE
Please confirm self heat rise within 10℃.

5. OPERATING TEMPERATURE
Use capacitors within the specified temperature range.
If used outside the specified temperature range, then the electrical characteristics may deteriorate significantly, leading
to failure.
The temperature referred to here includes the ambient temperature including heat produced by heat generating devices
(power transistors, resistors, etc.), self heating due to ripple current.
6. SOLDERING
1）
Soldering method
●MU series, MS series, MR series
MU series, MS series and MR series shall be used in reflow soldering and flow soldering methoed. Do not use in
VPS soldering method.
●ST series
ST series shall be used in only reflow method. Do not use in flow, dipping and VPS soldering method. Please confirm
your reflow conditions (reflow time, temperature). Soldering conditions should be according as recommended reflow
temperature profile.
●LDT series
LDT series shall be used in only flow method. Do not use in reflow and VPS soldering method.

※Floor life time is the case of humidity control under 30℃60%RH.
3）
Solder paste (Chip type)
A recommended thickness of solder paste is between 0.1mm to 0.2mm. The content of halogen in the soldering flux
should be 0.1wt% or less.
4）
Tentative mounting (Chip type)
This product can not be used again when the double-stick tape is used for tentative mounting.

Please contact us in advance if your condition is different with above.
7. CLEANING SOLVENTS
Please contact us in advance when cleaning of the PC board after soldering is necessary. If used improper cleaning
agent and/or ultrasonic, the capacitor may be damaged.
8. STORAGE CONDITION
①MU series/MS series/MR series/ST series: Please store capacitors under the normal temperature (5∼30℃) and normal
humidity(70%RH or less) without operating of moisture-proof bag.
Storage time limit (the state that a zipper of a moisture-proof bag was closed with dry silica gel) is within 1 month from
opening of moisture proof bag (Temperature: 5 to 30℃, Relative humidity: 70% or less). But, when the humidity of the
ambient environment keeps below 5%RH, it's possible to treat as the unopened position of moisture proof bag.
②LDT series: Please store capacitors under the normal temperature (5∼30℃) and normal humidity(70%RH or less) .
9. CONDITION OF USE
The following environment should be avoided when using capacitors.
①Damp conditions such as water, saltwater spray, or oil spray or fumes. High humidity or humidity condensation
situations.
②Hazardous gas/fumes (hydrogen sulfide, sulfurous acid, nitrous acid, chlorine, ammonia, bromine, etc.)
③Exposure to ozone, ultraviolet rays or radiation
10. DISPOSAL
In case of rejecting capacitors, please seek for professionals who deal with the industrial wastes management.
