Passive and electromechanical elements from Panasonic

2021-12-08

We have already written about the Panasonic offer in the TME catalogue many times – and yet there always comes an opportunity to mention new products and solutions offered by this prestigious Japanese manufacturer. Its products can be found in numerous parts of our catalogue – from simple to complex components of automation systems. Below, we will focus on the overview of the former category. These are basic, passive and electromechanical components that stand out for their high durability and precise manufacturing.

We kindly invite everyone interested in the full range of Panasonic products available from TME to view our catalogue by entering the following link.

Full offer of Panasonic products

Passive components and fuses

Firstly, let us look at the passive electronic components from Panasonic. They are suited for mass production and assembly processes – they allow for the construction of more precise and faultless circuits. It should be noted that most of the products described below are available directly from the TME warehouses, which allows us to minimalize shipment and delivery time.

SMD resistors

Panasonic’s SMD resistors with practically the whole range of parameters are available, thus fulfilling the needs of most of the production processes. First and foremost, precision resistors deserve a special attention. They stand out for their tolerance of 0.1%, 0.5% or 1% and, in the case of selected products, the thermal factor (the ability to change their resistance depending on thermal conditions) of 25ppm/°C. It is worth noting that for most of the products the permissible operating temperature ranges from -55°C to 175°C. These resistors can work with the voltage of 75V and 100V, and their nominal power is 100mW, 125mW, 250mW or 500mW. Products available in the offer are enclosed in 0402, 0603 and 0805 packages (from 1005 to 2012 according to the metric norm), and their resistance ranges from 0Ω to 1MΩ.

In the case of slightly more tolerant (up to 5%) resistors, the thermal factor ranges from 100ppm/°C to 600ppm/°C – which is still a sufficient specification for most electronic circuits. The nominal power of those components is 100mW, while the resistance range is from 0Ω to 10MΩ.

Conductive Polymer Tantalum Solid Capacitors

Among many different Panasonic capacitors in the TME offer, you can find Polymer tantalum components from the POSCAP series. They are made with the use of technologies developed by the supplier, suited for high-frequency circuits and standing out for their low resistance (low ESR) down to 5mΩ. Their main applications will be Embedded systems, communication and digital circuits. They are surface mount devices (SMD) with the capacitance from 10µF to 680µF (with a 20% tolerance), designed for voltages of 2,5V to 35V DC. Most products can work in temperatures from -55°C to 105°C. Of course, the POSCAP series is just a portion of all the capacitors from Panasonic that are available in our catalogue.

THT and SMD varistors

Varistors remain one of the most basic components securing electronic circuits, mostly those communication, power supply and control circuits, from voltage spikes. The Panasonic components of this category are mostly designed for THT mounting, but SMD elements are also available. Their maximum operating voltage ranges from 14V to 680V AC and from 16V to 895V DC, while the maximum current ranges from 300A to 10kA. In the case of the THT variants the pitch is 5 mm, 7.5 mm or 10 mm.

SMD power inductors

SMD inductor with the inductance of 33µH and 3mm profile.

Another necessary component of power supplies and other circuits that manipulates the electric current is a power inductor. With the development of precision and mobile electronics (ones that require compact converters & high power) these inductive components have undergone significant miniaturization and a drastic increase in current capability. Panasonic offers such power inductors through TME – these are inductors designed for Automotive grade surface mounting and high-current applications. It covers an inductance range from 0.33uH to 100µH. One of their important traits is the high thermal tolerance – they can work in temperatures ranging from -40°C to 150°C and are enclosed in packages with the footprint of 5.5x5mm to 10.9x10mm. Resistance does not exceed 348mΩ.

SMD fuses

Another Panasonic product group that is worth taking a closer look are miniature SMD fuses. This group comprises fast-acting and super-fast-acting fuses – standard components used in compact consumer circuits. They are applied, among others, in battery-powered equipment, in which a faulty cell or damaged power circuit can lead to high current fluctuations and major malfunctions. In the Panasonic range of products, there are single-use fuses for the voltage of 32V DC, in standard 0402, 0603 and 1206 packages. Rated currents (burn-out currents) of these components range from 500mA to 5A.

TACT microswitches

TACT microswitches are highly popular electromechanical components. They are widely used due to their small size and intuitive operation (the characteristic “click”, an audible signal that accompanies the closing of the circuit). There are many variants of these components on the market – with varied sizes, mounting options, IP rating, etc. In the TME’s offer, these are, among others, components by Panasonic – more than ten series of microswitches with a long lifecycle and mechanical endurance.

SMD microswitches

Switch with a height of 0.53mm, a standard component of compact mobile devices.

The miniaturization of electronic devices brought the need for manufacturing more and more compact switches – this trend results today in the widespread availability of low-profile TACT buttons, suited for reflow soldering (SMT mounting). The Panasonic range of such products includes switches whose profile does not exceed 0.35 mm (selected models), while their lifespan, electric parameters and thermal tolerance (which is particularly relevant when it comes to not only surface mounted components, but also those installed near current converters, battery cells, etc.) are really good.

EVPAA series

The EVPAA series includes very compact (footprint: 2.9 mm x 3.5 mm) TACT switches with the SPST contact configuration. The switching force of this components is from 1N to 5N, which makes them easy to use, but at the same time difficult to switch on by accident. They are typical components used in mobile (portable) devices. The switches are equipped with a large actuator (with the diameter of 1.8 mm), thanks to which they can be easily integrated with mechanical elements of an enclosure (e.g. in matrix keyboards for entering access codes).

EVQQ2 series

Switch with flexible button that absorbs excessive pressure.

EVQQ2 series products are designed for the devices that require mechanically resistant switches. This is thanks to both the guaranteed number of cycles of faultless work (up to 2 million with limited pressure. Additionally, microswitches are characterized by the relatively low contact bouncing (max. 10 ms). Thanks to that, these solutions are suitable for those applications in which they will be in constant use, but where a fast response to the user’s signal is required – in Home appliance, Remote access controls, game controllers or other HIDs (Human Interface Device, e.g. computer mice).
