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

Application Notes
When using TE's 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 (Printed Circuit Board).
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 to the 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.
