What is an MLCC capacitor?

The MLCC (Multilayer Ceramic Chip Capacitor) is one of the most widely used passive components in the electronics industry. Its structure stacks ceramic layers with internal Ag or AgPd electrodes, sintered at high temperature to form a monolithic chip. The result: a compact, reliable component suited for surface mounting (SMD), with high volumetric capacitance and a long service life.

It is found in computers, phones, telecommunications equipment, precision measuring instruments, radar systems, and many military and industrial devices.

The concrete advantages of the UF CAPACITOR’s MLCC range

• Wide choice of dielectrics — C0G/NP0 for high-frequency oscillating circuits, X7R and X5R for filtering and decoupling, Y5V and Z5U for general high-capacitance applications.
• Complete SMD formats — from 0201 to 1812, in T&R (tape & reel), RoHS compliant.
• High-voltage MLCCs — available up to 4 kV (e.g. 1812 package).
• RF / microwave MLCCs (High Q) — high reliability, low ESR, high Q factor, for base stations, radars and military systems.
• Military qualifications — MLCCs and tantalum capacitors produced with military qualifications.
• On-site UL laboratory — in-house quality control with a UL-recognized test laboratory directly within the factory.

A serious alternative to major brands

UF Capacitors positions itself as a direct alternative to TDK, Murata, AVX, EPCOS, Vishay and Panasonic, with equivalent quality and competitive lead times. The company counts among its references leading industrial groups: GE, Philips, Jabil and Flex.

ARTRONIK COMPONENTS SL is pleased to announce the establishment of a new strategic partnership with UF Capacitors, a Chinese capacitor manufacturer founded in 1995 and one of the most experienced players in its field. Through this collaboration, our customers now have access to a comprehensive range of high-quality capacitors — direct equivalents to the market’s leading brands — at significantly more competitive prices, with shorter lead times and dedicated support.

Who Is UF Capacitors?

UF Capacitors is an ISO 9001-certified Chinese manufacturer, founded in 1995. The company holds military qualifications for tantalum capacitors, MLCCs and other products, and operates a UL-recognised test laboratory directly on its production site.

Its market position is clear: to offer a superior alternative to first-tier brands such as TDK, Murata, AVX, EPCOS, Vishay and Panasonic, delivering equivalent quality at better prices, with shorter lead times and excellent service. UF Capacitors has built its reputation working with internationally renowned companies including GE, Philips, Jabil and Flex.

Today, the Topdiode Group — of which UF Capacitors is a part — reports annual revenues exceeding $50 million, with supercapacitor output alone reaching $10 million per year.

A Comprehensive Product Portfolio

UF Capacitors is one of the earliest capacitor manufacturers in China. It produces and sells four main families of capacitors: ceramic capacitors, tantalum capacitors, aluminium electrolytic capacitors, and film capacitors.

Ceramic Capacitors

UF Capacitors’ ceramic capacitors come in two main types: through-hole and surface-mount (SMD). Their high-voltage, high-capacitance ceramic capacitors are particularly cost-effective and widely used in home appliances, telecommunications, and safety products.

Available series include:

• CT4 — Radial multilayer ceramic capacitors (25 V to 4 kV), equivalents to Vishay K Series, TDK/EPCOS FK Series, Murata RPE Series
• CT41 — Chip MLCC SMD, equivalents to Murata GRM Series, Vishay VJ Series, TDK C1005 Series
• CT81 — High-voltage disc ceramic capacitors
• Y1 / Y2 Series — X1Y1 / X1Y2 safety ceramic capacitors (250 to 500 VAC), approved UL/CUL, CQC, VDE, ENEC, KC — pin-to-pin replacements for Vishay, Kemet, Panasonic, TDK/EPCOS and Murata

Tantalum Capacitors

Tantalum capacitors are available in both through-hole and SMD versions, primarily used in electric meters, IoT products and other embedded applications. Key series include:

• CA45 — Tantalum chip SMD (equivalents: Kemet T491, AVX TAJ, Vishay 293D)
• CA45U — Low ESR tantalum chip (equivalents: Kemet T494, AVX TPS)
• CA55 — Polymer tantalum (equivalents: Kemet T520, AVX TCJ, Vishay T55)
• CA42 — Radial epoxy dipped tantalum through-hole

Aluminium Electrolytic Capacitors

UF Capacitors’ aluminium electrolytic capacitors are primarily SMD V-Chip type, compact and high-performance, with series designed to replace Rubycon, Samwha, Nichicon and Panasonic:

• TCS — 85°C, V-Chip
• TCK — 105°C, V-Chip
• TFZ — 105°C, long life (2000–5000 h), ultra-low impedance
• TMA / TMB — Conductive polymer aluminium solid, 105°C, 2000 h
• Coin-type supercapacitors for electric meters, GPS, water meters

Film Capacitors

Film capacitors are valued for their excellent voltage tolerance. The range includes:

• CL21 — Metallised polyester (equivalents: Vishay MKT368, TDK/EPCOS B32520)
• CBB21 — Metallised polypropylene
• CBB81 — High-voltage metallised polypropylene
• X2 — Metallised polypropylene for mains interference suppression (equivalents: Kemet R46, TDK/EPCOS B32921)
