High Power & Adjustable Power Resistors

Ohmite has multiple part series for high-power applications. Parts range from thick film to wirewound and many can be attached to a heatsink for enhanced power dissipation. Due to multiple mounting options and constructions, Ohmite is confident customers will find the proper high-power resistor required to fit their needs. Adjustable Power Resistors are constructed so that their resistance can be readily changed.

Axial Lead Resistors

Most standard resistors are commonly produced in an axial lead style. The leads extend out horizontally from the body of the part. These parts are used in thru-hole PCB designs. The leads of this mounting design are bent down for insertion. Since the parts are received from the factory without any bends, it offers the end user the option to bend and mount per their application.

High-Voltage & Ultrahigh-Value Resistors

Ohmite has multiple part series for high-voltage applications. Due to multiple mountings and custom specifications, Ohmite is confident customers will find the proper high-voltage resistor required to fit their needs. With the custom specifications offered and multiple mountings, Ohmite high-voltage resistors fill the need for multiple applications including power supplies, avionics, medical instruments, and industrial controls.

Thick Film Resistors

What is a Thick Film Resistor?

Thick film resistors are produced by applying a resistive film or paste, a mixture of glass and conductive materials, to a substrate. Thick film technology allows high resistance values to be printed on a cylindrical or flat substrate either covered entirely or in various patterns. They also can be printed in a serpentine design to eliminate inductance, which is preferred in applications with steady frequencies. Once applied, the resistance is adjusted using a laser or abrasive trimmer.

Thick Film Construction

We offer over 20 different series in Thick Film construction. Thick Film parts can be chosen based on mounting, application, and voltage range. They are easily integrated into a heatsinkable package for high-wattage applications. High values can be obtained and high voltage can be applied to thick film products with little change in resistance value.

High-Energy Resistors

Transients, overloads, in-rush? Ohmite has you covered with a range of resistive products that can handle these high-energy events. From composition to unique thick film designs, Ohmite offers multiple product series that can take thousands of Joules. Axial, Radial, and Surface Mount designs are available to suit all needs and energy levels.

Threaded Inserts

Threaded inserts help strengthen plastic parts in which screws are installed and removed more than once, usually in thermoplastic or thermoset plastic. Most threaded inserts for plastics are made of brass because it provides a long thread life and secure fastening base, although other materials are also available. RAF provides threaded inserts in a variety of materials, styles, and sizes to meet the needs of different applications.

Specifications

Thread specifications include UNC-2B and UNF-2B for inch threads and ISO-6H for metric threads.

Materials

RAF offers threaded inserts made from a range of materials including

  • Brass
  • Aluminum
  • Stainless steel
  • Free-machining steel

CHERRY DW 9000 SLIM

The CHERRY DW 9000 SLIM desktop set stands out due to its innovative functions, excellent workmanship, and trendy, flat design.

The mouse and keyboard can be connected using the 2.4 GHz wireless USB receiver included with the set, or by Bluetooth®. You can switch connection types in an instant using a switch on the mouse or keyboard. This allows a laptop to be operated using Bluetooth®, as well as allowing a PC to be operated using the same desktop by means of a wireless connection with AES encryption. The data are transferred using an AES-128 encryption in both cases.

The CHERRY DW 9000 SLIM set features rechargeable lithium batteries that allow you to work throughout the week. You can then conveniently charge the mouse and keyboard using the micro USB cable included with the set, even while working. To ensure that the rechargeable batteries are still charged after a vacation, use a switch to turn off the keyboard and mouse altogether.

The keyboard contains an integrated metal plate, lending it optimal sturdiness and stability. Should you prefer a steeper angle while typing, you can adjust the keyboard using the four rubber feet included with the set. High stability is ensured by the metal plate, which prevents bending and bounding when typing.

The use of high-quality scissor mechanisms with a low keystroke ensures an ideal typing experience. Status LEDs integrated directly in each key provide information on whether the CAPS LOCK, SCROLL, and NUM keys are activated. In addition, these keys flash to warn that the battery charging status is low.

The six additional keys have proved to be extremely convenient and practical: “Windows lock,” “Open browser,” “Quieter,” “Louder,” “Mute,” and “Open calculator.”

The mouse, which harmonizes with the keyboard perfectly, also boasts a wide range of features. It fits ideally in the user’s hand thanks to its rubber-coated side parts and compact design. The resolution can be set in three stages at the touch of a button: 600, 1000, and 1600 dpi. A two-color status LED provides the user with information on the battery status, the charging status, the selected resolution, or the connection status at all times. An extra-durable mouse wheel with optical scanning and a magnetic storage feature for the USB receiver are further details that ensure nothing is left to be desired. The mouse is equally suitable for mobile and stationary applications.

Key Benefits

  • Optionally connected using Bluetooth® or a 2.4 GHz wireless unit – both with AES-128 encryption
  • Lithium batteries in the mouse and keyboard can be recharged via micro USB
  • Status LEDs show low residual battery charge, charging status, and mouse resolution
  • Additional status LEDs for the CAPS LOCK, NUM, and SCROLL keys
  • Extra-small nano receiver for wireless operation
  • 6 mouse buttons and a scroll wheel
  • Precise sensor with three-level adjustable resolution up to 1,600 dpi
  • Durable key lettering
  • Solid metal plate in the keyboard for maximum stability
  • Precise scissor mechanism for an ideal operating feeling
  • Rubber feet for individual height adjustment
