3. Tracking
Tracking on dual slide potentiometer is measured by follow ing formula with 2 V to 5 V applied voltage, at
1000±200 Hz between terminal 1 and 3.
Tracking error (dB)=20 log (V2/V1)
Where:
V1=output voltage of one side (between terminal 1 and 2)
V2=output voltage of the other side (between terminal 1 and 2)

Notes:
1. When you specify custom types (custom-made), new tooling and jigs, and/or equipment may be required. It will be necessary to confirm your
estimates of quantity and development schedule as accurately as possible.
2. Please inform us if you designate your own part number.
✽ Previous notations for potentiometer shape “Stand-up type” (Shaft is parallel to PWB.) and “Lay-down type” (Shaft is vertical to PWB.) – have
been changed in this edition to “Horizontal type” or “Side-adjust type” (Shaft or knob is parallel to PWB.) and “Vertical type” or “Top-adjust type”
(Shaft or knob is ver tical to PWB.).
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.

Slide Potentiometers
■
Application Notes
When using our Slide Potentiometers, please observe
the following items to prevent dangerous accidents and
deterioration of performance.
1. Prohibited items and notes in design stage
1. Use within the rating
The Power Rating or Maximum Voltage varies with
the size and type of a product. Also, the Power
Rat ing must be reduced according to a Power
Derating Curve. When a potentiometer is used with
a current of less than a few micro-amperes, the
influence of contact resistance increases because of
the circuit diagram. Check the potentiometer under
actual operating conditions.
2. Migration
Some potentiometers cannot be used with dc
voltage. If a potentiometer is to be used with dc
voltage, specify this when ordering, or check the
availability referring to the “Product Specifications for
Information.”
3. Anodization
W he n a p ote ntio m eter is
1
3
used with dc voltage –
2
under con di tions of high
humidity, the terminal at the
+
side of the wiper
(terminal 2) must be a positive electrode, as shown
in the figure at right.
4. Recommended Circuit Configuration
It is recommended that you use the variable resistor
for voltage adjustments. If it is used for current
adjustments, then it may be infl uenced by the
contact resistance between the resistor body and
the slide, depending on the target circuit conditions.
Conducting a test under actual operating conditions
is highly recommended.
5. Soldering conditions
When performing solder dipping, check the soldering
conditions according to the “Product Specifications
for Information”, because the conditions vary with the
product.
Do not wash a potentiometer after solder dipping
because flux may invade the potentiometer, resulting
in contact failure. Avoid use of jumper cables near
the potentiometers because flux may attach to them.
6. Operating temperature conditions
Tactile fe eling in o peratio n is give n serio u s
consideration, and rotation torque increases under low
temperatures (below–10 °C) depending on the
product. If a potentiometer is expected to be used
under low temperatures, specify this in advance.
2. Prohibited items and notes on handling
1. Terminal clinch
Bending and unbending of terminals af ter
mounting to a PWB must be one cycle or less. More
than one bending/unbending cycle may result in
damage.
2. Stress on the terminals
Do not apply excessive stress to terminals during
handling. Set soldering conditions with consideration
given to stress on the terminals.
3. Storage conditions
D o not store the potentio meters under high
temperatures and/or high humidity, or in a location
where corrosive gas may be generated. Store the
po ten ti om e ters at room temperature and room
humidity in a packed condition. Use them within
a ma ximum of 6 months. Check the date of
manufacture on the pack age box and apply the
“fi rst-in-fi rst-out” rule. If unpacked switches must
be stored as inventory, store them in a polyethylene
bag to keep out air.
3. Prohibited items on fire and smoking
1. Absolutely avoid use of a potentiometer beyond its
rated range because doing so may cause a fi re.
If misuse or abnormal use may result under
conditions in which the potentiometer is used out of
its rated range, take proper measures such as current
interruption using a protective circuit.
2. The grade of nonfl ammability for resin used in
potentiometers is “94HB,” which is based on UL94
Standards (fl ammability test for plastic materials).
Prohibit use in a location where a spreading fire
may be generated or prepare against a spreading
fire.
4. For use in equipment for which safety is requested
Although care is taken to ensure potentiometer
quality, inferior characteristics, short circuits, and
open circuits are some problems that might be
generated. To design a set which places maximum
emphasis on safety, review the affect of any single
fault of a potentiometer in advance and per form
virtually fail-safe design to ensure maximum safety
by:
1. preparing a protective circuit or a protective
device to improve system safety, and
2. preparing a redundant circuit to improve
system safety so that the single fault of a
po ten ti om e ter does not cause a dangerous
situation.
For notes on use, the following sources were referred:
Technical report EIAJ RCR-2191A “Guideline of
Notabilia for potentiometers for Use in Electronic
Equipment” issued by the Japan Electronics and
Information Technology Industries Association
(Issued by March 2002)
Refer to this Technical Report for additional details.
5. For actual use, be sure to refer to “Product
Specifications for Information.”
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
