Surface Mount Resistors

A surface mount resistor is a tiny rectangular ceramic body with silver conductive edges on either end. Also referred to as surface mount technology, an SMD resistor offers advantages in saving space on printed circuit boards (PCBs) and is the preferred resistor for use in electronics equipment due to the small size and high reliability. Surface mount resistors provide the same functionality as the more traditional axially leaded resistors but have a lower power dissipation capacity and oftentimes a lower stray inductance and capacity. TE offers standard thick film resistors and small SMD power resistors among a wide variety of surface mount resistors, including resistors suitable for specific applications such as pulse, surge, and voltage.

HPCR Series Resistors

TE Connectivity's HPCR series axial-leaded non-inductive bulk ceramic resistors provide excellent performance where high peak power or high energy pulses must be handled in a small size. The advantage of the bulk construction is that it produces an inherently noninductive resistor and it allows energy and power to be uniformly distributed through the entire ceramic resistor body; there is no film or wire to fail. As alternatives to hard-to-find carbon composition resistors, ceramic composition resistors can be used as drop-in replacements for 2 W sizes.

Chassis Mount Resistors

A chassis mount resistor is manufactured using wirewound resistor technology and features a ceramic core that is molded into an extruded aluminum chassis mount housing. The wirewound design maximizes pulse handling and the aluminum housing allows for superior heat conduction. TE’s chassis mount resistors are engineered for a variety of applications and are offered in 10 different power ratings ranging from 5W to 300W and are customizable to meet different pulse energy ratings and/or methods of connection to the customer’s equipment.

Thermistors

A thermistor is a temperature-resistant resistor that can have either negative or positive temperature coefficient of resistance, causing the resistance value to decrease or increase when temperature increases. A thermistor is useful when a specific temperature needs to be maintained, and when monitoring temperatures 50°C around the target temperature. TE offers negative temperature coefficient resistors, positive temperature coefficient resistors, leaded thermistors, and surface mount device thermistors. Thermistors are found in almost any product that requires heating or cooling protection circuits to ensure safe operation.

Potentiometers

Potentiometers are manually adjustable variable resistors that allow you to change and regulate the current flowing through a resistor and are used to adjust the level of analog signals, such as volume controls on audio equipment, and as control inputs for electronic circuits, such as light dimmers. Potentiometers are also found in a variety of applications where precise resistance in a current is required. TE offers Citec potentiometers with eyelet or PCB termination type, with a resistance as low as 10Ω or as high as 560KΩ and come either sealed or unsealed.

Probe Pads

TE’s probe pads, also referred to as test points, are incorporated in circuitry to avoid damage to sensitive tiny electronic circuits in surface mount devices (SMD), and enable the safe probing of circuitry when adjusting, setting up, measuring, or repairing the tiny electronic circuitry. Probe pads are packaged on tape for high speed automatic placement, and can be labelled and may include pins for attachment of alligator clips or may have connectors for test clips. The size of surface mount device probe pads offered by TE are relative to standard chip footprint areas. TE’s CGS series probe pads are offered in 0603, 0805, and 1206 size codes, with foil element offering resistance up to 1kΩ.

Test points have two primary uses:

Trimmer Potentiometers

A trimmer potentiometer, also known as a trim pot, is a type of variable resistor or adjustable potentiometer that can adjust, tune, and calibrate circuits. A trim pot is often used to initially calibrate equipment after manufacturing, and is meant to never be seen or adjusted by the device’s user. Unlike many other variable controls, trimmer potentiometers are mounted directly on circuit boards and tuned with a small screwdriver or knob or will have extended shafts that can be turned by fingers. Trim pots are commonly used in A/V components and may require adjustment when the equipment is being serviced. TE offers Citec series trimmer potentiometers with radial-leaded or surface mount of various power rating and resistance.

Transformers

A transformer is a passive electrical device which is designed to change one AC voltage to another by magnetic induction. It “steps up” or “steps down” voltage in order to match incoming supply voltage from the utility to the voltage required by the user’s end product. TE offers various types, such as Isolation Transformers, Autotransformers, Class II Transformers, and General Purpose Transformers.
