Vishay Intertechnology’s Thin Film High Frequency Chip Resistors Deliver More Power in Less Space, Without Need for a Heatsink

Vishay launches CHEP high frequency thin film chip resistors that boost power density to 2.8 W in standard 0402 and 0603 footprints.

Rhea-AI Summary

Vishay Intertechnology (VSH) introduced the Vishay Sfernice CHEP series of thin film high frequency chip resistors in compact 0402 and 0603 case sizes. These devices use an aluminum nitride (AlN) substrate to combine high power handling with RF performance in standard surface-mount footprints.

The CHEP series provides standard power ratings of 1.2 W (0402) and 1.8 W (0603), which can increase by 50 % to 1.8 W and 2.8 W when mounted per datasheet guidelines. Frequency capabilities reach up to 50 GHz for 0402 flip-chip, 20 GHz for 0402 wraparound, and 40 GHz for 0603 devices. With LC values as low as 1 x 10⁻²⁴ to minimize parasitics, the resistors support telecom, 5G/6G, LEO satellites, RF infrastructure, aerospace, and defense applications. They offer 20 Ω to 120 Ω resistance, ± 1 % tolerance, and operate from -55 °C to +155 °C. Samples and production quantities are available now with 16-week lead times.

Key Terms

aluminum nitride (AlN) substrate, low parasitics, flip-chip, RoHS-compliant

4 terms

aluminum nitride (AlN) substrate technical

"Built on an advanced aluminum nitride (AlN) substrate, the Vishay Sfernice CHEP series"

A ceramic wafer used as a base for mounting electronic components, aluminum nitride (AlN) substrate combines very good heat conduction with electrical insulation, so it draws heat away from chips while keeping circuits electrically separate. Think of it as a heat-spreading plate under a hot stove burner that prevents short circuits; its thermal and insulating properties affect device performance, manufacturing yields, cooling needs, and therefore product costs and market competitiveness.

low parasitics technical

"The resulting low parasitics reduce phase shift, maintain consistent impedance"

Low parasitics describes electronic components, circuits, or manufacturing techniques that minimize unintended resistances, capacitances, or inductances—parasitic elements that act like tiny friction or leaks in an electrical path. It matters to investors because lower parasitics typically enable faster switching, lower power loss, improved signal quality and higher manufacturing yields, so products or processes marketed as having low parasitics can indicate better performance, efficiency and competitiveness in high‑speed or low‑power markets.

flip-chip technical

"When mounted as flip-chip devices, resistors in the 0402 case size achieve frequencies to 50 GHz"

A flip-chip is a semiconductor packaging method where the bare integrated circuit (die) is turned face-down and attached to a circuit board or package using an array of tiny solder bumps or connections. This approach shortens electrical paths and improves heat removal, enabling smaller, faster and more power-efficient modules. It matters to investors because adoption affects chip performance, manufacturing cost, yields and the competitiveness of companies that make chips, packaging materials or assembly equipment.

RoHS-compliant regulatory

"RoHS-compliant, halogen-free, and Vishay Green, the devices operate over a temperature range"

RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.

CHEP Series Devices Offer Power Ratings Up to 2.8 W, High Frequency Operation to 50 GHz, and Low Parasitics in Compact 0402 and 0603 Case Sizes

MALVERN, Pa., Sept. 03, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of thin film chip resistors in compact 0402 and 0603 case sizes. Built on an advanced aluminum nitride (AlN) substrate, the Vishay Sfernice CHEP series combines exceptional power handling and high frequency performance in standard surface-mount footprints, allowing designers to achieve higher power density without sacrificing RF performance or increasing board space.

The CHEP series sets a new benchmark for power handling in its class. While competing solutions are often rated below 1 W, the devices released today deliver standard power ratings of 1.2 W in the 0402 case size and 1.8 W in the 0603 case size. When mounted per datasheet guidelines, power ratings increase by 50 % to 1.8 W and 2.8 W, respectively, enabling higher power density in smaller footprints.

The resistors operate across a wide frequency range and are available with flip-chip or wraparound terminals. When mounted as flip-chip devices, resistors in the 0402 case size achieve frequencies to 50 GHz, while wraparound active face-up mounting supports operation to 20 GHz. Devices in the 0603 case size support frequencies up to 40 GHz.

Designed to minimize internal reactance, the CHEP series features LC values as low as 1 x 10⁻²⁴. The resulting low parasitics reduce phase shift, maintain consistent impedance, and minimize noise to improve RF performance, while standard 0402 and 0603 case sizes enable easy integration into widely accepted land patterns, simplifying design and layout.

The devices are ideal for telecom and connectivity applications, including LEO satellites, base station terminals, 5G and 6G networks, and RF infrastructure such as remote radio units (RRUs) and antennas. Additional applications include aerospace and defense systems such as drones, satellite payloads, guidance and telemetry systems, data links, and phased array radar systems.

The resistors offer a resistance range from 20 Ω to 120 Ω with tolerances down to ± 1 % and a temperature coefficient of ± 100 ppm/°C, with ± 50 ppm/°C available on request. RoHS-compliant, halogen-free, and Vishay Green, the devices operate over a temperature range from -55 °C to +155 °C.

Samples and production quantities of the CHEP series are available now, with lead times of 16 weeks.
