Key Features
- 100 ohm resistance value in a compact 1/4-inch square body for precision bias and calibration adjustment
- Horizontal screw actuator orientation allows top-access adjustment with a standard flat-blade screwdriver without removing the PCB
- Through-hole mount with 0.46 mm lead diameter ensures secure mechanical anchoring and reliable solder joints on through-hole PCBs
- Single-gang (ganging number 1) configuration provides independent adjustment of one resistance circuit per trimmer
Applications
The T73XH101KT20 is used in analog circuit calibration, bias adjustment, and offset trimming applications where a 100 ohm variable resistance is required for field or factory setup. It is commonly found in instrumentation amplifiers, sensor conditioning circuits, and voltage reference trimmers where infrequent adjustments with a screwdriver are acceptable. Its through-hole construction makes it suitable for industrial control boards, test equipment, and audio electronics requiring stable, vibration-resistant trimmer mounting.

Frequently Asked Questions
What resistance value does the T73XH101KT20 provide, and what adjustment mechanism does it use?
The T73XH101KT20 offers a 100 ohm nominal resistance adjusted via a horizontal screw actuator. The screw mechanism allows precise incremental resistance changes using a standard flat-blade screwdriver, and the 1/4-inch square body retains its set position reliably after adjustment without mechanical drift under normal vibration levels.
How do the lead dimensions of the T73XH101KT20 affect PCB footprint and soldering in through-hole assemblies?
The T73XH101KT20 has lead diameters of 0.46 mm and lead lengths of 5.46 mm, designed for standard through-hole PCB pads with 0.6 mm to 0.8 mm drill holes. The 5.46 mm lead length provides adequate clinch-over and solder fillet on 1.6 mm thick boards, and the 1/4-inch square body sits flat on the PCB surface after insertion for stable hand or wave soldering.
In what calibration scenarios is a 100 ohm through-hole trimmer like the T73XH101KT20 preferred over a fixed resistor?
A 100 ohm trimmer is preferred when the exact resistance needed for accurate circuit calibration varies unit-to-unit due to component tolerances or sensor variation. Instrumentation amplifier gain-set networks, bridge-circuit null adjustments, and oscillator frequency-trim circuits all benefit from a 100 ohm adjustable element that can be dialed to the precise value required during factory calibration or field service, rather than replacing fixed resistors of different values.
