C0603

SMD MLCC Capacitors | C0603 Series

Product Introduction

C0603 Series (0603 imperial / 1608 metric) is the most universally adopted MLCC size in the electronics industry — a 1.6×0.8 mm SMD multilayer ceramic capacitor from YQM ELECTRONICS. As the de facto standard for general-purpose capacitor needs across all electronic product categories, the 0603 footprint delivers an unmatched combination of capacitance density, voltage range, assembly robustness, and global supply stability — making it the go-to choice for virtually every electronic device from consumer gadgets to industrial controls.

Spanning 0.2 pF to 22 μF with rated voltages from 4 V to 500 V DC, C0603 covers everything from precision RF matching to high-voltage power supply filtering in a single footprint. Three dielectric families — COG (NP0), X7R, X5R — with tolerances from ±0.1 pF to ±20%. Fully RoHS/REACH compliant, 260 °C reflow compatible, and supplied in 7"/13" tape-and-reel.

Core Advantages

• Industry-Standard 0603 Footprint: 1.6×0.8 mm — the most universally sourced MLCC size with decades of established multi-vendor supply chains, ensuring availability and competitive pricing across all capacitance/voltage combinations.
• Maximum Capacitance Coverage: 0.2 pF to 22 μF — the widest capacitance span of any standard MLCC series, from precision COG RF matching to high-capacitance X5R bulk decoupling, all in one footprint.
• Widest Voltage Range: Rated from 4 V to 500 V DC — covering 1.8 V logic rails, battery-powered devices, 48 V industrial buses, and high-voltage power supply filtering and snubber circuits.
• Universal Cross-Compatibility: Direct replacement for Murata GRM18, TDK C1608, Samsung CL10, and Yageo CC0603 — the most cross-referenced MLCC footprint globally. Identical pad geometry, zero PCB rework.
• AEC-Q200 Automotive Options: Automotive-grade variants available for infotainment, body electronics, LED lighting, BMS, and under-hood applications requiring extended reliability testing and PPAP documentation.

FAQ

Q: Why is 0603 the most popular MLCC size?

A: 0603 (1.6×0.8 mm) offers the best balance of capacitance density, voltage range, assembly yield, and multi-source availability. It is large enough to support up to 22 μF and 500 V, yet small enough for high-density PCB layouts. Almost every MLCC manufacturer offers a full 0603 portfolio, ensuring supply chain resilience.

Q: Is C0603 a direct replacement for Murata GRM18 or Samsung CL10?

A: Yes. C0603 shares identical 0603 package dimensions, pad footprint, and tape-and-reel format. Matching capacitance (0.2 pF–22 μF), voltage (4–500 V), and dielectric (COG/X7R/X5R) ranges — direct drop-in replacement with zero design changes.

Q: Can C0603 be used at 500 V?

A: Yes. C0603 offers rated voltages up to 500 V DC in X7R dielectric with appropriate capacitance values. For high-voltage applications, consult the derating guidelines — typically operate at ≤50–70% of rated voltage for maximum reliability. Contact YQM for detailed voltage/capacitance matrices.
