Murata posted news in the website that trimmer capacitors will be discontinued after 2021 March. As a competitor, we suppose that TZR1 Series (Ultra-small and thin with external dimensions of 1.5(W)x1.7(L)x0.85(H)mm) and TZW4 Series (Compact size: 4.2(W)x5.2(L)x2.6max.(H)mm) have no replacement product in the market for the same capacitance and size.

Could you please think about using Kingtornics ceramic trimmer capacitors KKT series small size with external dimension of 3.2(W) x 4.5(L) x 1.5(T) mm? Unique construction with no plastic material provides superior soldering heat resistance to maintain excellent characteristic performance after reflow soldering. It is suitable for high frequency circuit due to high self-resonant.

A wide range of applications coupled with low costs and high accuracy make NKT NTC thermistors a frequently used device. The applications performed by these devices allows for thermistors to function as accurately as they do. NKT NTC Thermistors are used in a wide range of different industries that require high accuracy when it comes to temperature. Some of the applications include:

Temperature compensation: considering that temperatures fluctuate as a result of their environment, NTC thermistors are able to compensate for changes to keep temperature where it needs to be. Examples of circuits that might require compensation are, LCD displays, charging batteries, oscillators, HVAC( Heating, Ventilation and Air Conditioning) and refrigeration equipment

Inrush current limiting: not only is a NTC thermistor subject to a change in temperature, but it is also susceptible to changes in power. When there are changes in power, a NTC thermistor experiences a time lag prior reaching lower resistance. The time lag is utilized to help limit the inrush surge currents. It used for medical industry including catheters, dialysis equipment, and patient monitoring.

Temperature measurement: If low cost, longevity, and accuracy are important qualities, a NTC thermistor is the best option. For the operating of dryers, coffee devices. Automotive and aerospace industries use NKT NTC thermistors for test and measurement as well as production applications

Fluid level gauging: A thermistor will be able to sense an absence or presence of a liquid. It is able to do this through measuring the difference between dissipation constants (between a gas and a liquid).

Selection Criteria
The initial considerations for trimmer type selection are:
A. Resolution of adjustment
B. Setability and time to set

C. Physical and environmental conditions

D. Stability of setting required

E. Circuit packaging requirements
 

C. Physical and Environmental Issues

1. Physical considerations in trimmer selection
• Case style desired
• Top or side adjust
• Pin style required
• Mechanical support required
• Board height requirements

2. Assembly process considerations
BI offers a variety of trimmer models that are sealed to help protect against moisture and board washing processes.
•Open vs. Sealed
• Max time/temperature exposure 

3. Environmental operating considerations
• Operating temperature range
• Resistance temperature coefficient
• Vibration and shock tolerance 

4. Human operating conditions When you complete your design, be careful to consider the tortures that clever human beings with a screwdriver in hand can impose on trimmers. For example, while a trimmer configuration mounted on edge might be a board space saver, a trimmer that mounts flat on the board may be more resistant to abuse by a heavy handed technician making adjustments through a hole in the chassis.

Selection Criteria
The initial considerations for trimmer type selection are:
A. Resolution of adjustment
B. Setability and time to set

C. Physical and environmental conditions

D. Stability of setting required

E. Circuit packaging requirements

B. Setability and Time to Set
The enemies of setability are poor resolution, mechanical backlash and high CRV. BI has addressed these problems in the design of trimmer models. BI’s smooth cermet materials, precious metal split brush contacts and teflon rotors work together to provide outstanding setability.

E. Circuit packaging requirements

A. Resolution of Adjustment
1. Multiturns
 Multiturns provide better resolution than single turns. Models with a longer element exhibit better resolution than those with a short element. Typical multiturn shaft revolutions range from 15 to 20 turns for end to end travel.
 The contact design and stability are important considerations in achieving high resolution. The contact area must be small and the contact must move smoothly in order to provide high resolution. A noisy contact will make accurate setting very difficult.
 All trimmers utilize smooth cermet materials, precious metal wire brush contacts and backlash-free wiper designs that ensure high resolution setability.
 Reference multiturn models:
Square multiturns - 44, 64, 66, 67, 68
Rectangular multiturns 78, 89

2. Single Turns
 Single turn resolution for models with a longer cermet element (larger diameter) is quite respectable. This is especially true with wire brush contacts and smooth cermet films.
 Reference single turn models:
Small diameter - 24, 25, 62, 82
Larger diameter - 72, 91, 93

3. Surface Mount Models
 Single turn - 21, 23, 83
 Multiturn - 44, 84

A trimmer can be used as potentiometer or rheostat. A potentiometer is a three terminal device typically used to vary voltage. In potentiometric configurations, the wiper terminal is lightly loaded so that wiper current is generally small.

A rheostat is a two terminal device typically used to control current. Wiper current is generally larger in rheostat circuits.

I. Types of Applications
The majority of applications for trimmers occur in electronic circuits. 
Typical uses are in the following devices:
A. Amplifiers
B. Timing circuits

C. Voltage and current regulators

D. Voltage and frequency converters

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval.
