Your choices are...
|
|
|
| |
Pulse Transformer
|
|
Pulse transformers interface a pulse forming network (PFN) and a load. They match the impedance of the load to the PFN in order to maximize power-transfer efficiency.
|
| |
Telecom / LAN / Ethernet Transformer
|
|
The telecom transformer is used in applications that require high bandwidth and fast switching speeds. The signal is isolated between primary and secondary grounds. LAN and Ethernet transformers are specific telecom transformers used in networking applications.
|
| |
Audio Transformer
|
|
An audio transformer is ideally suited for voice and data transmission. The frequency response of these transformers typically ranges from 300 Hz to 20 kHz.
|
| |
Current Sense Transformer
|
|
Current sense transformers are generally used to detect and measure current. There are basically two types of current sense transformers, those designed and used to precisely measure current in accurate instrumentation applications and others designed and used in switch-mode power converter type applications. In power conversion applications, current transformers are used to measure trends, peak values, and average values rather than absolute values. As a result, these devices do not need to have a very high degree of accuracy, but rather need to be efficient, dense, and exist in many shapes and styles capable of supporting all traditional types of manufacturing processes.
|
| |
Power Transformer
|
|
Power transformers convert one voltage to another at high power level.
|
| |
High Voltage Transformer
|
|
High voltage transformers are used in situations where a high voltage is needed.
|
| |
Balun Transformer
|
|
A balun transformer is a device used to interface a balanced line (two conductors carrying equal currents in opposite directions) to an unbalanced line (one conductor carrying current and a ground). Its name is derived from the terms applied to Balanced to Unbalanced lines.
|
| |
Trigger / Gate Drive Transformer
|
|
Trigger / gate drive transformers are used to drive high speed switching devices such as FETs and IGBTs electronics. They are commonly used in applications like switching power supplies.

Topology / Configuration

Your choices are...
|
|
|
| |
Push-Pull
|
|
Transformers are used in push-pull configuration circuits, such as power supplies.
|
| |
Flyback
|
|
Flyback transformers use the flayback or kickback of an inductor to convert an input voltage to a desired output voltage. The input voltage or charging cycle produces energy which is stored in the inductor. The input energy or discharge cycle is then transferred to the output.
|
| |
Boost
|
|
Boost or step-up transformers convert a lower DC input voltage to a higher DC output voltage of the same polarity.
|
| |
Forward (Buck)
|
|
Buck or step-down converters are used to convert a higher DC input voltage to a lower DC output voltage of the same polarity. Forward converters are similar to buck-boost converters, but use a transformer to store energy and provide isolation between the input and output. The difference between flayback and forward transformers is in the way the energy transfer takes place. Flyback transformers have two distinct phases for energy storage and delivery. By contrast, forward transformers transfer energy from input to output in a single step.
|
| |
Bridge
|
|
Transformers have a bridge (half or full) output configuration.

Your choices are...
|
|
|
| |
BNC
|
|
Bayonet Neil-Concelman (BNC) connectors were designed for military applications, but are used widely in video and RF applications to 2 GHz. BNC connectors have a slotted outer conductor and a plastic dielectric that causes increasing losses at higher frequencies. BNC connectors are usable above 4 GHz as long as the slots radiate signals; however, these devices may not be mechanically stable to 10 GHz. Both 50 and 75 BNC connectors are available. BNC connectors are also known as bayonet navy connectors or baby Neil connectors.
|
| |
MCX
|
|
Miniature coaxial (MCX) connectors provide broadband capability through 6 GHz and are used in applications where weight and physical space are limited. They provide good electrical performance and are used to address the rapid implementation of the U.S. digital cellular PCN infrastructure. MCX connectors are also used in global positioning systems (GPS) and wireless LAN (WLAN) applications.
|
| |
Mini-UHF
|
|
Mini-UHF connectors are a miniature version of the original UHF connector. They feature a threaded coupling mechanism for reliable mating. Mini-UHF connectors are designed for use in cellular mobile telephone systems where size, weight and cost are critical. With crimp cable termination for low installation costs, these connectors provide excellent RF performance in applications through 2.5 GHz.

Micro-miniature coaxial (MMCX) connectors are smaller than MCX connectors and feature a more robust interface for greater durability. They are ideal for high volume, wireless SMT or PCMCIA applications in cellular base stations, cellular phones and personal communicators. MMCX connectors are also used in global positioning systems and wireless LAN (WLAN) applications.

Threaded Neil-Concelman (TNC) connectors are similar in size to BNC connectors but feature a threaded coupling nut for applications that require performance to 11 GHz. TNC connectors are durable, reliable devices that are widely used in the cellular and mobile communication industry for equipment cabling and antenna interfaces.

Type F connectors have a screw-type coupling and frequency range up to 1.5 GHz. Applications include CATV, TV, and antennas.
|
| |
Type N

|
Type N connectors include an integrated gasket to protect against environmental ingress and create an air gap between the center and the outer conductor. They primarily have 50 impedance, but 75 versions for CATV, are available.
|
| |
UHF
|
|
Ultra high frequency (UHF) connectors are economical, all-purpose connectors designed with non-constant impedance for use in comparatively low voltage and low frequency applications such as citizens' band (CB) communications systems. UHF connectors are also used in public address systems, closed circuit television (CCTV), civil defense, landing systems, ground control apparatus, ship-to-shore communications, and mobile radio equipment hookups between antenna and transmitters or receivers.
|
| |
1.6 / 5.6
|
|
1.6 / 5.6 connectors are mechanically sturdy devices that feature a coupling mechanism. They are often used with equipment that requires resistance against environmental and mechanical stress. 1.6 / 5.6 connectors are also suitable for handling RF analog and digital signals in telecommunications systems.
|
| |
7-16
|
|
7-16 connectors are designed for use in medium to high power communication systems. These connectors perform exceptionally well in multichannel cellular systems where power levels approximate 100 watts per channel. Designed for both flexible as well as corrugated cables, these connectors are used in a variety of cellular base station and broadcast communication applications.
