Sensors monitoring mechanical and biological systems must often scavenge power from the thing being sensed. The oscillator circuits shown here let you operate those sensors. Sensor circuits that connect to thermocouples, electromagnetic mechanical-to-electrical transducers, and piezoelectric mechanical-to-electrical transducers often use oscillators powered through energy harvesting from solar cells and other sources. These power sources can […]
Inductors
Inductors and all-mode filters now for frequencies up to 5 GHz
SMP Sintermetalle Prometheus GmbH & Co KG (SMP) has extended the frequency range for inductive components and filter systems. Filter damping in all-mode products now has an effective range of up to 5 GHz. SMP manufactures and develops EMC filter systems and inductive suppression components based on All Mode Technology (AM), a registered trademark of […]
When reality intrudes on component models and equivalent circuits
Determining the utility of an equivalent-circuit model versus construction reality is often a difficult challenge. Using simplified, first-order approximations in models and equivalent circuits is a normal part of engineering life. Without them, we would get mired in the details and harsh reality of the components and their characteristics. We would never be able to […]
Non-magnetic RF inductors reach values up to 18 µH
A new non-magnetic RF thru-hole (leaded) inductor series, 28MG, was designed to address the market need for non-magnetic inductors that could achieve inductance values of up to 18 µH. This series is a candidate for use in medical imaging equipment and other applications where magnetic materials must be avoided, including use in telecommunications, security systems, […]
Ultraminiature multilayer ceramic chip inductors work up to 10 GHz
AVX Corporation released a new series of ultraminiature multilayer ceramic chip inductors for high-frequency RF applications. The new LCCI Series inductors are currently available in three standard EIA chip sizes — 0201, 0402, and 0603 — with tight-tolerance physical dimensions almost exclusively in the submillimeter range and tin-plated surface-mount terminations, enabling compatibility with high-density PCBs […]
Chip inductors designed for automotive audio bus apps
Bourns, Inc. announced its new 1210-size automotive-grade common-mode chip inductor series. Bourns’ latest family of common-mode inductors are designed with a ferrite core and are bifilar-wound to deliver a compact size and shielded construction. The Model SRF3225AB and SRF3225TAC common-mode chip inductor series offer low radiation and high impedance over a broad frequency range to suppress Electromagnetic […]
MLCCs sport 1.0 µF ±20% values for 4-Vdc-rated automotive apps
Murata announced the ultra-thin LW reversed, low equivalent series inductor (ESL) multilayer ceramic capacitor (MLCC) with a capacitance value of 1.0 µF ±20% for 4 Vdc-rated automotive applications. With a 0204-inch size (0.5 x 1.0 mm) footprint and a maximum thickness of just 0.22 mm, the LLC152D70G105ME01 decoupling capacitor can be implemented on the back […]
SMD ceramic inductors feature high Q, high thermal stability
Würth Elektronik has expanded its WE-KI product family with further ceramic inductor variants in 0603 and 0805 packages. Now the portfolio includes over 300 models in four sizes from 0402 to 1008, optionally with ±2 and ±5 percent tolerance. With the new range of models, the available inductance values cover 1 to 1800 nH. The […]
What are RF inductors?
Radio frequency (RF) inductors have several uses and are available in various construction types to suit the performance needs of specific applications. Matching, resonators, and chokes are common uses for inductors in RF circuits. Matching involves eliminating impedance mismatches and minimizing reflection and losses in the lines between circuit blocks such as the antenna and […]
