Type CT6 Series
This miniature trimmer incorporates the
latest technology developments and
has been rigorously tested to the
highest standards. Special Attention at
the design stage has created a new
resin moulded technology which is
ideally suited to high volume, low cost
applications in a range of consumer
and industrial markets. The CT6 is also
available taped and ammo packed
for extra high-speed insertion. The
cross-slot head is designed for
automatic adjustment and the CT6 can
also be adjusted from both sides.

Application Notes
When using our Trimmer Potentiometers, please observe the following items (“prohibited items”) and be careful of the
following in order to prevent dangerous accidents and deterioration of performance.
1. Prohibited items and notes in design stage
1. Use within the rating.
The affect of the ambient temperature on trimmer potentiometers cannot be ignored. When using at a high temperature,
reduce the load according to the Power Derating Curve above.
2. Handling trimmer potentiometers.
Take care not to apply excessive stress to a trimmer potentiometer after mounting it to a PCB.
3. Anodisation.
When dc is applied to a wiper (terminal 2), anodisation may occur at the contact part of the
wiper with the resistive element, resulting in abnormal resistance variation. When dc is used,
to prevent anodisation, the resistive element should be connected to the negative side and
the wiper should be connected to the positive side, as shown in the figure at right.
2. Prohibited items and notes on handling
1. Storage.
Do not store trimmer potentiometers at high temperatures and /or under conditions of high humidity, or in a location where
corrosive gas may be generated. In particular, when storing for long periods, do not unpack the trimmer potentiometers and
do not store them as a single unit.
2. Operational direction.
Since the stopper strength at the rear side is 35mNm, which is smaller than at the front side, operation for adjustment from
the front side is recommended.
3. Prohibited items on fire and smoking
1. Absolutely avoid use of a trimmer potentiometer beyond its rated range because doing so may cause a fire. If misuse or
abnormal use may result in conditions in which the trimmer potentiometer is used out of its rated range, take proper
measures such as current interruption using a protective circuit.
2. The grade of non-flammability for resin used in trimmer potentiometers is “94HB,” which is based on UL94 Standards
(flammability test for plastic materials). Prohibit use in a location where spreading fire may be generated or prepare against
a spreading fire.
