Power Management ICs (Power Management Integrated Circuits) allows electronic devices to function efficiently without quickly draining the battery. A PMIC may have multiple functions such asbattery management, voltage regulation, charging functions.

Power management ICs are solid state devices that control the flow and direction of electrical power. Many electrical devices have multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power (e.g., wall outlet, battery, etc.), meaning that the power design of the device has multiple requirements for operation.

A PMIC can refer to any chip that is an individual power related function, but generally refer to ICs that incorporate more than one function such as different power conversions and power controls such as voltage supervision and undervoltage protection. By incorporating these functions into one IC, a number of improvements to the overall design can be made such as better conversion efficiency, smaller solution size, and better heat dissipation.

A coaxial RF connector (radio frequency connector) is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers.

Common types of RF connectors are used for television receivers, two-way radio, certain Wi-Fi devices with removable antennas, and industrial or scientific measurements instruments using radio frequencies. Our range includes:

• BNC connectors - used with many different types of RF coaxial cable and come at various impedance specs.
• N-type connectors - available in 50- and 75-ohm models. They're available with a range of options for cable type, connector type, mounting type and more.
• SMA connectors - available in standard and subminiature sizes, in a wide range of different mounting types and termination methods.
• RF & coaxial adapters - allow different types of cables to be connected and come in various impedance ratings, contact plating, operating frequencies and more.

An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices.

RF modules are most often used in medium and low volume products for consumer applications such as garage door openers, wireless alarm or monitoring systems, industrial remote controls, smart sensor applications, and wireless home automation systems. Our range includes:

• Low power RF modules, are typically used for communication. They can be applied to many different types, shapes and sizes of small electronic sub-assembly circuit board.
• Bluetooth modules, we offer low energy modules for Bluetooth technology which means they have a low power consumption rate.

A passive filter is a kind of electronic filter that is made only from passive components – in contrast to an active filter, it does not require an external power source (beyond the signal).

Since most filters are linear, in most cases, passive filters are composed of just the four basic linear elements – resistors, capacitors, inductors, and transformers. More complex passive filters may involve nonlinear elements, or more complex linear elements, such as transmission lines.

We work with respected manufacturers like TDK, Schaffner, TE Connectivity and EPCOS, and stock a range of passive filters under our RS PRO brand for even better value.
