Product Overview

GJM0335C1E4R0WB01D is a core model of the GJM Series high-Q chip multilayer ceramic capacitors (MLCCs) from Murata, designed for general electronic applications with a rated voltage of ≤100Vdc, focusing on high-frequency application requirements. Adopting advanced "High Precision Lamination Technology" and "Fine Particle Ceramic Material", this product achieves high Q-value and low high-frequency dissipation. It complies with the EU RoHS Directive 2011/65/EU for environmental protection and is manufactured in Murata's ISO 9001-certified factories (e.g., Wuxi Murata Electronics Co., Ltd.), ensuring high reliability. With a precisely controlled capacitance of 4.0pF and C0G (EIA) temperature characteristics, it maintains capacitance stability over a wide temperature range of -55°C to 125°C, making it suitable for circuits requiring strict signal accuracy and high-frequency performance, such as RF modules, oscillation circuits, and high-frequency filter circuits.

Key Features

• Ultra-High Q-Value & Low High-Frequency Dissipation：By optimizing ceramic and electrode designs, low dissipation is achieved in VHF, UHF, and microwave frequency bands, reducing signal attenuation and improving high-frequency circuit efficiency—this is the core advantage of GJM0335C1E4R0WB01D for high-frequency scenarios.
• Excellent Temperature Stability (C0G Characteristic)：Following the EIA C0G temperature standard, the capacitance change rate is only ±30ppm/°C within the operating temperature range of -55°C to 125°C, ensuring stable circuit performance in extreme environments and avoiding functional deviations caused by temperature fluctuations.
• Precise Capacitance Control & Minimal Tolerance：The fixed capacitance of 4.0pF with a strict tolerance of ±0.05pF (corresponding to tolerance code "W") meets the strict capacitance accuracy requirements of high-frequency tuning and oscillation circuits, reducing circuit debugging complexity.
• Environmental Compliance & Global Adaptability：Fully compliant with the EU RoHS Directive 2011/65/EU, restricting hazardous substances such as lead, mercury, and cadmium. It is also compatible with major global electronic equipment environmental standards, suitable for export-oriented product designs.
• Miniaturized Size for High-Density Layout：With physical dimensions of 0.6x0.3mm (EIA 0201) and a height of only 0.3mm, the compact size fits high-density PCB layouts in smartphones, industrial sensors, etc., saving space costs.

Typical Applications

• Consumer Electronics (Smartphones/Tablets)：In smartphone RF modules and Wi-Fi 6/Bluetooth high-frequency circuits, the high Q-value and low dissipation of GJM0335C1E4R0WB01D reduce signal interference, ensuring communication speed and stability. Its miniaturized size fits the high-density PCB layout inside smartphones, meeting thin and light design requirements.
• Communication Equipment (Routers/Switches)：Used in high-frequency filter circuits of routers and signal tuning modules of switches, its C0G temperature characteristic ensures stable capacitance during long-term device operation (-55°C~125°C), avoiding communication packet loss or speed degradation caused by temperature rise, suitable for home and industrial communication scenarios.
• Industrial Control (Sensors/PLCs)：In oscillation circuits of industrial pressure sensors and flow sensors, the 4.0pF±0.05pF precise capacitance tolerance ensures the accuracy of sensor output signals. Combined with ISO 9001-certified high reliability, it meets the strict requirements for device stability (MTBF) in the industrial control field.
• Automotive Electronics (Infotainment Systems)：Adapted to high-frequency signal processing circuits of in-vehicle navigation and car audio, it meets the wide-temperature operating requirements of automotive electronics. The environmentally compliant material prevents the release of hazardous substances in the automotive environment, and its long-term stability adapts to the 5+ year service life design of automobiles.
• Medical Electronics (Non-Implantable Monitoring Devices)：Used in signal processing circuits of small heart rate monitors and blood glucose monitors, the RoHS-compliant feature and low-power design (low ESR) adapt to the environmental protection and battery life requirements of medical devices, while the precise capacitance ensures the accuracy of monitoring data.

Why Choose GJM0335C1E4R0WB01D ?

• Outstanding High-Frequency Performance for Complex Signal Scenarios：Compared with ordinary MLCCs, the high Q-value (Q≥1000 in high-frequency bands) of GJM0335C1E4R0WB01D significantly reduces signal attenuation, making it especially suitable for high-frequency applications such as 5G RF and microwave oscillation, improving circuit signal-to-noise ratio.
• Industry-Leading Temperature Stability：The C0G temperature characteristic results in a capacitance change rate of only ±30ppm/°C over -55°C~125°C, far superior to materials like X7R (±15%), avoiding circuit failures in extreme temperatures (e.g., industrial high-temperature environments, automotive low-temperature startup).
• Precise Tolerance Reduces Debugging Costs：The minimal tolerance of ±0.05pF reduces capacitance dispersion, eliminating the need for additional screening during mass production. It directly adapts to high-precision circuits (e.g., high-frequency oscillators), shortening product R&D and production cycles.
• Full-Link Compliance for Worry-Free Global Markets：It meets EU RoHS, China RoHS 2.0, and US EPA environmental standards simultaneously. The manufacturing factories are certified to ISO 9001/14001, allowing the product to be directly used in electronic equipment exported to major global markets such as Europe, America, Japan, and South Korea.
• Murata Quality Endorsement & Stable Supply Chain：As an original Murata model, GJM0335C1E4R0WB01D relies on Murata's global production network (factories in Japan, Singapore, Wuxi China, etc.) to ensure stable mass supply, avoiding stock-out risks of niche brands.
