C0201

SMD MLCC Capacitors | C0201 Series

Product Introduction

C0201 Series (0201 imperial / 0603 metric) is YQM ELECTRONICS' ultra-miniature SMD multilayer ceramic capacitor (MLCC) lineup — the smallest standard MLCC form factor in mass production at just 0.6×0.3 mm. Purpose-built for high-density PCB designs where every square millimeter counts, this series is the capacitor of choice for smartphones, true wireless earbuds, smartwatches, and wearable medical devices.

The series spans 0.1 pF to 1 μF with rated voltages from 6.3 V to 50 V, supporting all three mainstream temperature characteristics — COG (NP0) for Class I ultra-stable applications, X7R for industrial-temperature decoupling, and X5R for cost-sensitive consumer designs. Manufactured with advanced thin-layer nickel-electrode technology under stringent quality control, C0201 capacitors deliver excellent capacitance stability, low ESR/ESL, and reliable high-frequency performance. Fully compatible with standard 260 °C lead-free reflow soldering and supplied in 7-inch tape-and-reel for high-speed SMT assembly.

Core Advantages

• Industry's Smallest MLCC: 0.6×0.3 mm footprint — the smallest standard MLCC size available, enabling ultra-compact designs that are impossible with larger capacitors.
• Triple Dielectric Flexibility: COG (NP0) for ±30 ppm/°C stability in timing circuits; X7R for ±15% across -55~+125 °C industrial range; X5R for cost-effective consumer decoupling — all in one footprint.
• Full Cross-Compatibility: Direct pin-to-pin replacement for Murata GRM02, TDK C0603, Samsung CL03, and Yageo CC0201 — identical 0201 pad layout, zero PCB redesign.
• Precision Tolerances: ±0.1 pF, ±0.25 pF, ±0.5 pF for COG; ±5%, ±10%, ±20% for X7R/X5R — meeting RF matching accuracy through bulk decoupling needs.
• High-Speed SMT Ready: 7" tape-and-reel packaging compatible with 260 °C lead-free reflow and automated pick-and-place — optimized for high-volume production lines.

FAQ

Q: Is C0201 Series a direct drop-in replacement for Murata GRM02 or TDK C0603?

A: Yes. C0201 shares identical 0201 (0.6×0.3 mm) package dimensions, pad layout, and tape-and-reel format with Murata GRM02, TDK C0603, Samsung CL03, and Yageo CC0201. Matching capacitance, voltage, and dielectric options — no PCB or BOM changes required.

Q: What is the difference between COG, X7R, and X5R dielectrics?

A: COG (NP0) offers ±30 ppm/°C ultra-stable characteristics — ideal for timing, filtering, and resonant circuits. X7R provides ±15% stability across -55~+125 °C for industrial decoupling. X5R offers ±15% across -55~+85 °C, optimized for cost-sensitive consumer applications where wide temperature range is not critical.

Q: Can C0201 be used in automotive applications?

A: Standard C0201 is rated for consumer and industrial temperature ranges. For automotive-grade applications requiring AEC-Q200 qualification, please contact YQM for availability of automotive-compliant variants with extended reliability testing.
