Capacitor Solutions Across the Power and Signal Chain

LiDAR and advanced sensing systems rely on precisely controlled laser pulses, stable power delivery, low-noise receiver electronics and high-speed signal processing. These technologies are used across airborne mapping, autonomous platforms, industrial inspection, scientific instrumentation and space-based observation. Pulsed time-of-flight architectures can require nanosecond-scale optical pulses, while their receivers demand high bandwidth and low noise to detect weak returned signals.

Evans Group brings together four specialized capacitor technologies—Evans hybrid wet tantalum, Paktron multilayer polymer film, UTC multilayer ceramic and Eulex RF/high-frequency ceramic—to help engineers address electrical requirements throughout the LiDAR power and signal chain.

From Pulse Generation to Precision Measurement

Every LiDAR measurement begins with the controlled transmission of laser energy and ends with the processing of a reflected signal. Capacitor requirements can vary significantly across that architecture.

Evans Group technologies can support functions including:

Pulse-energy storage and rapid energy delivery
Input, output and DC-link filtering
Power-conversion and switching circuits
Ripple-current handling and voltage stabilization
Local bypassing and decoupling
EMI and noise suppression
High-frequency coupling and DC blocking
Impedance matching and tuning
Power hold-up and transient response

The appropriate capacitor technology depends on pulse energy, voltage, repetition rate, ripple current, frequency, ESR, ESL, temperature, available space and environmental requirements.

Capacitor Technologies for LiDAR and Sensing

Evans

Hybrid Wet Tantalum for Power-Dense Energy Storage

Evans hybrid wet tantalum capacitors combine high capacitance, ultra-low ESR and high power density in compact packages. Within LiDAR and advanced sensing platforms, they can support bulk energy storage, power hold-up, bus stabilization and rapid, repeatable energy delivery where size, weight and power are critical.

Their high capacitance density makes them particularly relevant to airborne, defense and space systems that must deliver substantial energy from a limited footprint. Evans also offers capacitor banks and configurations for demanding shock, vibration and temperature environments.

Potential LiDAR functions: Pulse-power support, bulk energy storage, power hold-up, transient response and power-bus stabilization.

Paktron

Multilayer Polymer Film for Power Conversion and Filtering

Paktron’s proprietary stacked multilayer polymer technology provides self-healing performance, low ESR and ESL, strong ripple-current handling and high mechanical reliability. These characteristics make Paktron capacitors well suited to switched-mode power supplies, DC-to-DC converters, filtering networks and other power-conversion stages within LiDAR and sensing platforms.

Paktron film capacitors can support voltage smoothing, L-C filtering, EMI filtering, coupling and decoupling, DC blocking, snubbing and lower-energy pulse functions. Their construction offers an alternative to traditional wound film and ceramic technologies where dependable operation and stable power delivery are required.

Potential LiDAR functions: DC-link filtering, converter input and output filtering, ripple-current handling, voltage smoothing, snubbing and EMI filtering.

UTC

High-Reliability Ceramic Capacitors for Power Integrity and Noise Control

UTC designs and manufactures standard and custom high-reliability multilayer ceramic capacitors, including low- and mid-voltage MLCCs, SMPS capacitors, high-voltage capacitors, pulse-energy capacitors, discoidals and planar filter arrays.

Within LiDAR and sensing systems, UTC technologies can support local decoupling, power-supply filtering, EMI suppression, pulse-discharge circuits and stable operation of analog, digital and timing electronics. High-voltage and high-temperature options can also address demanding aerospace, space, defense and industrial environments.

Potential LiDAR functions: Decoupling, bypassing, EMI suppression, power-supply filtering, pulse-energy circuits, high-voltage operation and high-temperature electronics.

Eulex

RF and High-Frequency Ceramic for Signal Integrity

Eulex RF capacitors use an embedded-electrode architecture engineered for high capacitance density, ultra-low parasitics and broadband performance. These characteristics can support the high-frequency circuitry associated with LiDAR receiver electronics, fast timing systems, optical modules and high-speed signal-processing architectures.

Eulex technologies are designed for functions such as DC blocking, RF bypassing, filtering, coupling, tuning and impedance matching. Low-inductance options can help engineers maintain power and signal integrity where conventional capacitor performance becomes limited by ESR, ESL or self-resonance.

Potential LiDAR functions: High-frequency bypassing, DC blocking, filtering, coupling, impedance matching, tuning and noise suppression.

Supporting LiDAR on Earth and in Space

LiDAR enables precise measurement across a wide range of platforms and environments, from aircraft and autonomous systems to orbiting scientific instruments. NASA’s ICESat-2, for example, uses a photon-counting laser altimeter to measure ice sheets, sea ice, vegetation, land elevation and ocean height from space.

Evans Group capacitor technologies can support LiDAR and sensing systems used in:

Airborne and space-based remote sensing
Geospatial mapping and surveying
Autonomous navigation and robotics
Defense detection, ranging and targeting
Atmospheric and environmental measurement
Industrial inspection and metrology
Infrastructure and terrain monitoring
Scientific and archaeological research

Select the Right Technology for Your Design

No single capacitor technology is ideal for every point in the LiDAR architecture. A system may require power-dense energy storage near the transmitter, film capacitors within the power-conversion stage, ceramic capacitors around processing electronics and high-frequency RF capacitors within sensitive signal paths.

Evans Group engineers can help evaluate requirements across the complete system, including:

Voltage • Capacitance • Pulse width • Repetition rate • Peak current • Ripple current • ESR and ESL • Operating frequency • Temperature • Size • Shock and vibration • Qualification requirements
