MLCC Complete Series for Global Sourcing｜General, High Voltage, RF & Non-Magnetic
Multilayer Ceramic Chip Capacitors (MLCCs) are one of the most critical passive components in modern electronics. From smartphones and EV power inverters to RF front-ends and medical imaging equipment, engineers rely on stable and flexible SMD Multilayer Ceramic Capacitors to keep their designs running safely and efficiently.
jb Capacitors Company offers a complete SMD Multilayer Ceramic Capacitors portfolio covering general-purpose, high-voltage, RF high-Q, and non-magnetic solutions. This article introduces four key SMD series – JYS, JYT, JYU, and JYV – and how they support global sourcing requirements for different application segments.
1. JYS – General-Purpose SMD MLCC Series
The JYS series is the workhorse of the jb SMD Multilayer Ceramic Capacitors family, designed for high-volume, general-purpose use in consumer, industrial, and telecom electronics.
- Capacitance range: 0.1 pF to 100 µF for signal coupling, decoupling, and bulk capacitance
- Rated voltage: 4 V to 50 V DC to match low-voltage logic and power rails
- Dielectrics: NP0, X7R, X5R, X6S, X7S, Y5V for different stability and capacitance density needs
- Package sizes: 0201, 0402, 0603, 0805, 1206, 1210 and larger sizes on request
- Applications: decoupling, bypass, filtering, timing, coupling, general signal conditioning
With a broad selection of capacitance values, voltage ratings, and dielectric options, JYS is ideal for global sourcing teams that need a single, consistent SMD MLCC platform to cover most positions on the PCB.
2. JYT – High-Voltage SMD Ceramic Chip Capacitors
The JYT series is engineered for high-voltage and high-reliability environments, such as lighting ballast circuits, DC–DC converters, analog front-ends, and industrial power systems that still demand compact SMD Multilayer Ceramic Capacitors instead of bulkier through-hole parts.
- Rated voltage options: 100 V, 200 V, 250 V, 500 V, 630 V, 1 kV, 2 kV and above (model-dependent)
- Dielectrics: NP0 / NPO and X7R for stable capacitance over temperature
- Low dissipation factor: supports efficient operation under high electric field stress
- Suitable soldering methods: reflow, wave, and hand soldering for flexible assembly
- Typical uses: high-voltage sensing, snubber networks, power factor correction, inverters
For designers who need extra safety margin on surge and steady-state voltage, JYT provides a compact and robust high-voltage SMD Multilayer Ceramic Capacitors option compared with bulky film or leaded components.
3. JYU – SMD High-Q RF Capacitors
The JYU series targets RF, microwave, and high-frequency analog circuits where low loss and high Q are mandatory. It is well suited for 5G infrastructure, RF modules, and precision analog designs that rely on carefully selected SMD Multilayer Ceramic Capacitors for tuning and matching.
- Dielectric system: C0G / NP0 with ultra-stable temperature coefficient
- High Q and low ESR: minimizes insertion loss in resonant and matching networks
- Capacitance stability: low drift over temperature, voltage, and time
- Typical applications: VCOs, LNAs, power amplifiers, filters, impedance-matching networks
JYU is optimized for RF designers who need predictable, repeatable capacitance values up to the GHz range, allowing precise tuning and consistent production performance with high-quality SMD MLCC components.
4. JYV – RF High-Q Non-Magnetic Multilayer Chip Capacitors
The JYV series extends jb’s RF portfolio with a non-magnetic MLCC platform for highly sensitive RF and medical applications where conventional SMD Multilayer Ceramic Capacitors can introduce unwanted magnetic effects.
- Non-magnetic construction: avoids magnetic interference in MRI and precision RF systems
- High-Q, low ESR: supports clean signal paths with minimal loss
- Stable NP0 dielectric: excellent temperature and frequency stability
- Target markets: MRI coils, NMR equipment, medical imaging, high-end RF instruments
By combining non-magnetic materials with high-Q performance, JYV helps engineers eliminate distortion and artefacts that can be introduced by conventional magnetic MLCC constructions, while still benefiting from the footprint and assembly efficiency of compact SMD capacitors.
