Shunt Resistors and  Sensors Application in Unmanned Aerial Vehicles

Shunt Resistors and Sensors Application in Unmanned Aerial Vehicles

The industrial investment in unmanned aerial vehicles (UAVs) is soaring due to their multiple partially or fully autonomous applications such as aerial photography, rescue operations, surveillance, and scientific data collection. Current sensing for battery of UAVs is critical for determining battery capacity in order to calculate the remaining flight time, and detecting fault. Magnetoresistive sensors are highly suitable for current sensing on UAVs due to their higher accuracy, lower energy consumption, and smaller size than...

How to Choose Resistors'  Performance?

How to Choose Resistors' Performance?

Naturally, not every engineer needs an entire high-performance package for their circuitry. Resistors with much poorer specifications can be used satisfactorily in many applications, so the question of need is divided into four basic categories: Existing applications that can be upgraded by relying on the total performance package of Metal Foil resistors. Existing applications that require one or more, but not necessary all, of the performance parameters to be industry best. State-of-the-art circuitry that can only be develop...

MELF Resistors' Merits, Constructions and Sizes

MELF Resistors' Merits, Constructions and Sizes

Another form of SMD resistor that can be used is known as the MELF resistor - Metal Electrode Leadless Face. These resistors are not nearly as widely used as the standard SMD resistors, but in some instances they provide advantages and can be used. MELF resistor are more expensive than the more widely used SMD resistors, they are able to provide higher levels of performance in terms of long term stability, moisture resistance, reliability, and the resistance to the effects of temperature cycling experienced int he soldering p...

Thick Film Resistor Present Market and Development Trend

Thick Film Resistor Present Market and Development Trend

Thick film resistors are being produced by firing a special paste onto the substrate. The paste is a mixture of glass and the metal oxides. Thin film has got a thickness in the order of 0.1 micrometer or even smaller, while the thick film is around thousands time thicker in comparison to that. However, the main difference is the method the resistive film is applied onto substrate. Thin film resistors have got a metallic film which is vacuum deposited on an insulating substrate. Thin film resistors and thick film resistors are...

Renewable Energy Refresh the Ammeter Shunt Resistor

Renewable Energy Refresh the Ammeter Shunt Resistor

The rise of renewable energy has put ammeter resistors back in the spotlight. The world has turned to renewable energy in an attempt to wean itself from depleting carbon-based sources. The increase in the number of solar, wind, wave, and tidal power sources has pushed the need for a highly accurate method of measuring current where ammeter shunt resistor FL-2 type from Microhm Electronics are widely used for this purpose. The solution is required for several reasons: to ensure accurate billing, have a more granular level of c...

Miniature future for passive electronic components – Resistors

Miniature future for passive electronic components – Resistors

Passive electronic components are getting smaller, but they are also providing better performance within the same form factor. Twenty years ago form factors such as 1812 and 1206 were widely used. Todays most commonly specified sizes are 0603 and 0402. The range extends down to 01005 (0.4 x 0.2 mm), and recently even to just 008004 (0.25 x 0.125 mm!). Microhm Electronics thick film resistor LMK series and NRC series start with the size 01005. For shunt resistor, the size can be down to 0805. The trend in SMD (surface mount de...

Linear Resistors’ Market Situation

Linear Resistors’ Market Situation

Over the past 24 months the global resistor markets have been in turmoil. The turmoil was created by a shortage of thick film chip resistors. This in turn caused the price of ruthenium metal to increase, and the availability of aluminum substrates to be constrained. Subsequently customers looked to alternative technologies in nickel-chromium resistors to satisfy shortfalls in ruthenium/alumina resistor supplies. As a professional resistor manufacture, thick film resistor is also one of the main product lineup for Microhm Elec...
